School of the Future

Just practicing as much as you can or thinking before you start practicing – which is more efficient?

Otoato
I believe most people aiming to become good at the piano practice by simply playing over and over again. However, our investigation showed that, even if it means cutting down on the time spent actual playing, what’s important is to think about how you should play in order to improve, while practicing. That’s why we created ‘otoato’, a system to support practice. Otoato sorts out the content of your practice to make it easy to understand, just like a teacher. For example, in the ‘heat map’ function, places where you made a lot of mistakes during practice are colored red, while places where there were few mistakes are colored blue. By looking at the heat map, you can tell at a glance which parts you have difficulty with and where you make a lot of mistakes. Furthermore, there is a function that enables you to add memos about things you have noticed or need to think about. Utilizing memos such as “Next I should practice this part more” allows you to think of personalized practice methods. Using otoato enables you to reflect on your practice while improving more efficiently at the same time. Why not have fun rethinking your piano practice with otoato?

Tablet Stone

Realizing a curling stone that maintains a stable information display no matter how much the stone is spinning
Tablet Stone is an application that was developed for players of curling. This application begins with the placing of a tablet on top of a curling stone. On the tablet, information such as the stone’s movement speed, rotation speed and number of rotations is displayed. This information is important for, for example, the sweepers (the players who sweep the ice with brushes). However, because a curling stone spins as it travels, it is difficult for the sweepers to read information displayed on top of the stone. By making the information display rotate in response to the rotation speed of the stone as it slides across the ice, we make it easy for players to read the data. But seeing is believing, so check out the demo video!

Keyboard Cover

Turns even the quietest person into a chatterbox
A computer keyboard is a multi-functional device that can be used not just for typing, but also for operations involved in gaming, music, design, and so on. However, most applications largely involve operations using specific keys or mouse buttons, which are different for each application, meaning that operation is counter-intuitive and takes time to get used to.
This is where Keyboard Cover comes in handy. Keyboard Cover comprises a plastic sheet with small extrusions, which is fitted over a computer keyboard. Attaching Keyboard Cover enables you to add new interfaces, such as dials or sliders, to the ordinary keys, transforming a single keyboard into various types of controllers. Keyboard Cover can reduce instances of accidentally pressing the wrong key and make operation more intuitive, thus improving operational efficiency. Also, as the layout of the cover can be customized to suit the purpose of an application, you can create the optimum operation environment for you. If you’re struggling with keyboard operation, why not let Keyboard Cover inhabit your keyboard?

Reflection Stamps

A more enjoyable way to reflect on your drawings. A simple and positive feedback tool.
Reflection Stamps is a tool that makes it easy to reflect on an illustration you have drawn. People who don’t like reflecting on their work often feel that ‘I only notice the bad parts’ or ‘I don’t want to look at my drawings.’ To enable such people to enjoy reflection, in Reflection Stamps you can place text stamps on the parts of an illustration that you like or want to improve. For example, by looking at your illustration and adding stamps such as “The hair looks soft; it looks good!” or “I want to adjust the balance of the eyes a little,” it’s easy to sort out the good parts and the parts you want to alter. As the result of an experiment, we found that using Reflection Stamps makes reflection take less time-consuming and encourages a positive feeling during reflection. In the future, we plan to increase the variety of stamps to enable even more diverse expression, and to improve the usability of the tool. Using Reflection Stamps allows anybody to reflect positively on their own illustrations.

Afterward Auxiliary Lines

Lines that follow your drawing

Achieving correct balance is one important aspect of drawing. Accordingly, many people draw guide lines in advance, as a means of drawing with correct balance. However, the problem with conventional auxiliary lines is that it becomes necessary to adjust the lines again and again as the drawing progresses. This is where ‘Afterward Auxiliary Lines’ comes in. In Afterward Auxiliary Lines, auxiliary lines are displayed automatically in response to the illustration that is being drawn, removing the need to alter the auxiliary lines manually. Furthermore, drawing that is completely dependent on auxiliary lines does not exercise the drawer’s powers of observation, but with Afterward Auxiliary Lines it is possible to draw and make alterations while looking at one’s own illustration, the object or motif that is being observed and the auxiliary lines, enabling the user to draw while learning observation skills. Why don’t you try this easy way of improving your drawing skills with the assistance of these clever auxiliary lines?

Painted Musical Instrument

Create any electronic musical instrument by drawing

Painted Musical Instrument is a device that enables you to create any kind of electronic instrument you like, simply by drawing on paper. Usually, we use instruments that already ordinarily exist in the world, but if we were able simply to create original instruments that do not yet exist anywhere in the world, our dreams would expand. For example, you could easily make an instrument suited to your own body size, which might allow you to play difficult parts of music with ease, or play with a greater range of expression. Besides this, when you apply the Painted Musical Instrument device, being able to turn a staircase, chair, doorknob, handrail, or any household item, into an instrument need not be a mere dream. 50 or 100 years in the future, the instruments most widely used may not be those designed by well-informed instrument experts, but those casually designed by children or people with no musical experience.

PerformMask

A versatile expression-changing mask for use in performance

Masks are often used in performances such as children’s plays. As a mask has a fixed appearance, the expressions it can convey are limited. Perform Mask can flexibly change its appearance, expressing for example changes of expression, age, gender, meaning that one mask can be used for multiple scenes or roles. First of all, ink that changes color by heat transmisison is applied to the part of the mask that one wants to change. Then, copper tape is simply adhered to the underside of the area to which ink was applied. Thus, anybody can create an original ‘mask of a hundred faces’.

Dance Instrument and Projection Dance

Dance Instrument and Projection Dance

Dance Instrument is a new expression tool for dancers. In breakdancing, dancers take part in dance battles in which opponents compete by demonstrating their dance skills. Dance Instrument plays impressive sound effects at appropriate moments during dance, in time with the BGM. Projection Dance produces slick visual effects. Producing sound effects and visual effects just at the right moment – there is actually an amazing technology behind that.

Baatarina

Support for finding your position in stage performance

A dancer or singer’s stage performance involves confirming his/her position on the stage in advance, during rehearsal. Performances will not necessarily always be given on the same stage. Stages come in all shapes and sizes and this greatly affects a performer’s position on the stage, especially in the case of dancers or singers. There are times when sufficient rehearsal time cannot be spent on confirming position. To enable a performer to check whether he/she is in the correct position, we attach an HMD (a glasses-type display). We support performance by displaying information on the HMD that allows the performer to confirm where he/she is on the stage and whether he/she is in the proper position.

Projection Mapping LED

The possibility to produce light displays on even bumpy surfaces

It is very difficult to project onto, for example, a Christmas tree, which is has an uneven surface and is not white. There are LED cables that can be wrapped around a Christmas tree, aren’t there? With these, it is easy to make all the lights shine or flash, but, when it comes to creating a pattern, things get a lot more complicated. Projection Mapping LEDs are hi-tech LEDs with sensors that detect the color of light from a projector. By lighting up only the LEDs that the light from a certain specialized projector has shone on, you can make a pattern appear.

Danmaranai

Turns even the quietest person into a chatterbox

In online video meetings, it has been observed that, when compared to face-to-face meetings, it is difficult to see the gaze, expressions, hand gestures and movements of the person or people to whom one is talking, which often prevents meetings from progressing smoothly. On top of this, for shy people who are passive when it comes to online communication, it is hard to speak in an online meeting environment, thus such people tend to turn off their cameras or mute themselves. Accordingly, we considered that by visualizing ‘gaze’, which is usually not conveyed online, we can enable discussions involving shy people to run more smoothly, and make it easier for shy people to speak. In this research, we had online participants conduct group work using Post-it notes, and measured the movement of their gaze when they looked at each of the Post-it notes, on which opinions had been written. As a result, we found that participants looked longer at notes on which opinions of agreement were written than at notes on which opposing opinions were written. Furthermore, by displaying the notes that were viewed for a long time with increased color saturation, we made non-speaking participants’ opinions of agreement easily noticeable, which reduced the length of silences between participants and enabled the meeting to proceed more smoothly and for a longer time. In online meetings, shy people worry too much about how others will react and hesitate to express their opinions, but we think that if we can turn shy people into chatterboxes by visualizing their gaze, we can surely have more enjoyable discussions in future!

Projection Piano

The shortcut to piano mastery

To become able to play the piano, there are many hurdles to overcome, such as learning to read music, practicing fingering and maintaining rhythm, and learning how to apply strength when pressing the keys. Furthermore, it is very hard to learn these skills alone, causing some players to become disheartened partway through. Projection Piano is the answer to such a problem. Projection Piano is designed to reduce the hurdles that tend to trip up people starting to learn the piano and make piano practice fun. By practicing with Projection Piano, a player should be able to enjoy mastering the piano without becoming disheartened along the way.

Score Gazing

The eyes don’t lie

You may not find it difficult, when sat next to someone who is playing the piano, to follow his place on the score with your eyes. However, when a computer system tries to do the same thing it is not so straightforward. Playing tempo changes constantly according to expression, and there are times when a note may not be played or a mistake made. In practise the player may also miss out difficult parts and repeatedly practice the same places. By using not only sound and input to the musical instrument, but also combining these with gaze information, the score gazing system follows the score as though it is right beside the player, to support performance.

Rendan

Joining the dots to connect piano lessons and practice

When taking piano lessons, it is essential to practice individually at home. However, there is a problem, in that it is difficult for the teacher accurately to grasp how the student has practiced at home. This is where Rendan comes in. Rendan is an application that visualizes the state of a student’s piano practice so that it can be understood at a glance. On the home screen, a calendar is displayed, and on each date there is a donut graph expressing amount of practice and number of keying errors. Detailed figures can be checked by selecting a date. In addition, it is possible to confirm not only the amount of practice on a single day, but also to compare that day with the amount of practice conducted to date, which makes it easy to understand how much a student has progressed. Furthermore, amount of practice can even be confirmed at the level of bars or notations, with places that have been practiced a lot displayed in a darker color, enabling the teacher to confirm amount of practice at a glance. While Rendan is aimed at piano teachers, it can also be used for a parent to check their child’s practice, or to help students themselves to get an accurate understanding of the state of their own practice.

Erasure-Oriented Illustration Method

Slow and steady wins the race when it comes to skill acquirement

There is a saying (slow and steady wins the race) which means that, if you want to hurry, you can sometimes get there more quickly in the end by taking the long way round. What happens if we apply the essence of this to skill acquisition (Illustration)? As an example, we considered an erasure-oriented illustration method, which incorporates the idea of ‘erasing’ as you draw. In actual practice this means, when drawing a shape like a UFO, for example, simply drawing two overlapping circles then erasing the unneeded parts. How does that sound? Don’t you think you could draw better that way than by trying to draw the shape of a UFO as it is? When you master this illustration method, you become able to draw more complex illustrations, skillfully. By taking the long way round, you are able to draw more easily and simply. Sounds like a pretty good method, don’t you think?

AnoPers

Imagining and drawing a motif seen from a different perspective

When beginners learn digital illustration, they tend to practice by copying or sketching flat images, whereas in reality the quickest way to improve is to practice drawing three dimensional motifs as much as possible. In the proposed system, the learner repeatedly performs the training task of imagining how a three-dimensional motif, displayed on a computer, looks from a specified viewpoint and drawing it. The learner can use the computer interface to change the viewpoint. However, to prevent the learner from seeing the correct answer, there is a fixed area, centered on the specified viewpoint, that cannot be viewed. This idea was partly informed by a type of spatial awareness training called mental rotation. The results of an experiment showed that the system improved users’ ability to draw angle, size and position both accurately and three-dimensionally. Having a grasp on three-dimensional drawing enables an illustrator to draw the kind of difficult compositions, involving low angles and overhead views, that are used in action-packed manga.

Table Cutting Board

With this, you too can handle a knife like a top chef

Tablet cutting-board is a system to improve the user’s technique of cutting ingredients with a knife. Before cutting ingredients, the thinness of slices is set in advance. When ingredients are cut on top of the tablet, the system displays whether or not they have been cut to the appropriate width, in real time on the tablet screen. Tablet cutting-board can judge the width of cut ingredients with an accuracy degree of within 0.5mm. It would not be exaggerating to say that this makes its judgement accuracy higher than that of a professional chef. Beginners often make the mistake of cutting to an appropriate width, but in a diagonal direction. Usually, it is difficult to notice when the knife is at a diagonal, but Tablet cutting-board uses sound to notify the user of whether or not the knife is horizontal. In this way, this system supports the first step towards mastering knife-handling technique. Incidentally, you may wonder whether it’s really okay to use a tablet as a cutting board, but relax; a tablet’s glass screen is a lot stronger than you’d think!

Tablet Handwriting

Transcription in which a learner practices using a brush on a tablet

Instances of writing by hand are decreasing, but people still enjoy receiving handwritten letters and greetings cards. To write characters neatly, it is essential to consider the correct order of penstrokes and the balance of each character. Practising writing with a brush is worthwhile, even if just to learn the history of the characters. However, in addition to the difficulty of using a brush, which is probably unfamiliar, one must consider balance and brush control while comparing with a sample image. This makes it very difficult to tell, just by looking, whether or not the character is drawn correctly. In tablet calligraphy, the user can learn character balance by placing a piece of Japanese calligraphy paper over a tablet displaying an example character, and tracing with a brush dipped in water. Characters written are automatically assigned a score, enabling users to understand their progress in terms of a numerical value.

Stone Recoder

Turning curling stones into science

Often called `chess on ice’, curling is known to be a competitive sport that is extremely tactical. However, how the stones used in the sport will move on the ice, and the physical mechanism involved, have yet to be made clear. StoneRecorder uses infrared LEDs and an infrared camera to record the movement of stones and displays their trajectories on the rink, using projection mapping. Making it possible to visualize or predict the trajectory of the stones could change both tactics and practise, and even the nature of spectation.

Smart Bowling Ball

Perceptive bowling ball

To become good at bowling, it is necessary to consider various factors, such as approach, form and the speed and number of rotations of the ball. However, it is impossible to grasp exactly what state the ball is in once it has been bowled. Smart Bowling Ball has several sensors embedded in it, endowing it with sensory information. By reading the information recorded by the ball, such as speed and rotation, it is possible to confirm the status of the ball after bowling, in more detail and in numerical values. Perhaps we will see a future in which the ball itself gives you advice on your bowling.

How much do I need to practice to improve?
Practise or study with no end in sight is hard and frustrating. Doubtless everyone has experienced a period during which their skills do not improve even though they practice, or of feeling uncertain during a slump in progress. Simply by being shown current practise outcomes, test results etc., `Teacher who is good at prediction’ estimates how a person will progress in future, from a vast amount of past records. The future prospect of improving if you practice this much, study this much, becomes an incentive to overcome the difficult periods.

Teacher with a Knack for Analogy

Teaching through comparison to daily movements

In sport or playing instruments, when using the body in a different way from in everyday life, it can be difficult to visualize what you need to do to master certain skills. `Teacher with a knack for analogy’, uses comparison to everyday actions to teach those ways of using the body that are difficult to visualize. By inputting all kinds of everyday action, this system can tell you the daily action in which the way you use your body is closest to the action of a professional. When you learn which of your everyday actions is similar to the action of a pro, you can more rapidly become competent at a sport or an instrument.

Teacher who Deliberately Overlooks, or even Covers up, Your Mistakes

To keep learners motivated

Acquirement of skills that use the body takes a long time. Noticing mistakes is the first step to achieving correct movement. A ‘computer teacher’ can unfailingly notice even slight mistakes made by learners. However, if all these mistakes are pointed out to learners, they will feel they are always being criticized and come to loathe practice. ‘Teacher who deliberately overlooks mistakes’ selects the mistakes that will be pointed out to learners, based on their proficiency levels. Furthermore, the system covers up certain mistakes, for example, by outputting the correct sound from a piano even when an incorrect key has been pressed. But you worry about whether you can actually improve by practicing in this way, don’t you? Don’t worry. You will improve.

Teacher who Doesn’t Overlook the Little Things

Advice from a viewpoint you cannot see with your own eyes

When you go to have piano lessons, the teacher has to consider not only score reading and practice methods, but also fingering, posture and even your musical way of thinking. However, there is a limit to the area that a single teacher can look at. In particular, paying attention to every minute movement and placement of the fingers is very difficult. `Teacher who doesn’t overlook the little things’ scrutinizes your piano practice from viewpoints from which the teacher cannot, and gives advice. Of course, this concept is not limited to learning the piano. The system could watch over practice of other instruments and sports from every angle, to support progression.

Multimodal Teacher

Teaching through a variety of methods

When learning skills that use the body, such as sport, playing a musical instrument, or cookery, in books there is no choice but to learn from visual expression such as text and diagrams. If you attend lectures or classes you can learn from a teacher, but with `Multimodal Teacher’ you can learn skills through experiences, more richly, thanks to a teaching presentation style produced by the combination of several components, such as sight, sound and touch.

Teacher who Lies, out of Love

For graduation from the support system (teacher)

There are many systems to aid with the acquisition of skills in sport, music and so on, but at some point you have to become independent of the system and able to perform skills by yourself. ‘Teacher who lies, out of love’ helps you to graduate from this kind of support system (the teacher). The majority of support systems (teachers) teach the correct way of doing something, but this system begins to tell lies once the user has learned to perform a skill as taught. Being lied to causes the user gradually to come to mistrust the system (teacher). Finally the user is no longer misled by the system’s (teacher’s) lies, and can become independent.

Teacher reminding you when you couldn’t do it

Enabling a teacher to provide singing instruction appropriate to their student’s lung capacity

To improve singing technique and performance, it is essential to manipulate your body appropriately, such as by controlling your breathing. However, in actual singing lessons, teachers often use abstract phrases to instruct. Breathing with the physical ability of a teacher (adult) and breathing with the physical ability of a student (child) are different, thus, a student requires instruction that is appropriate to their physical ability. Therefore, we developed a band-type device for singing teachers. By singing with the band fitted around the lower part of their chest, a teacher can experience the difference between their own physical ability and that of their student. The band senses chest movements and recognizes whether the wearer is breathing in or out. Then, the system displays a graph depicting residual respiratory volume (how much breath is left). The line on the graph goes up when the user breathes in, and down when the user breathes out. For example, if the residual respiratory volume gauge is set altered from 100% to 75%, in accordance with the student’s respiratory volume, by singing while keeping their breathing within the range of the residual respiratory volume gauge, the teacher can understand how it feels for the student. In this way, the teacher becomes able to instruct in a way that is suited to their student.
