what is it:
Soundbrace turns our arm and fingers into an guitar. Wearing it enables you to play music whenever you want even without an instrument.
technology:
it uses sensors as follows: detector to sense the activity of electricity of are muscle; motion capture camera (IR);
Whenever you turn your arm, the muscle produce electricity. By classifying those signals, Soundbrace can know what is the direction of your turn. Also motion capture cameras produce IR so it can tell if a finger blocks IR and the distance between camera and the finger. Thus it can sense the gesture of hand.
interaction:
Play it like playing a guitar but without a real one.
value:
It is a physical-digital devices which augment our daily life. The principle of it is gesture detecting which is hot area of research. Sound brace is just a interesting application of that research. If I'm rich (just a poor student..) I want to buy one to see the instantaneity and accuracy of the brace. However, wether it is good or not, I think, with the development of sensors, I think the physical-digital devices will replace instruments sooner or later and be put into many other applications freeing people from heavy and cumbersome equipments.
Project #2: Digits: Freehand 3D Interactions Anywhere Using a Wrist-Worn Gloveless Sensor
what is it:
Digits is a wrist-worn sensor that recovers the full 3D pose
of the user’s hand.
technology:
IMU, IR Laser Line Projector, IR Camera
IMU, IR Laser Line Projector, IR Camera
interaction:
This technology is used to detect gestures. It can make many applications such as shooting games or virtual reality. Programmers can do a lot of things if they acquire the data of gestures in realtime.

value:
I have seen their demo before so I know its instantaneity is quite well. Without calculating all the depth data of hands, it uses laser lines to get the distance of some points of fingers, which simplifies the computation and raises the speed. At the same time this device is comparatively smaller than some devices (such as Kinect).
