BlackBelt is a wearable gadget that augments martial actions with cinematic sound effects.
Inspired by Kung Fu costumes, the gadget takes the form of hand wraps, with electronics embedded inside fabric. Out of a total of five, four are wrapped around wrists and ankles, each embedded with a sensor that detects wearer’s strike. One has a speaker, and is worn around waist. The waist belt communicates wirelessly with the four limbs, and plays striking sound effects when action is taken. All sounds effects are pre-recorded and saved on a SD card. Just wrap on BlackBelt and play!

The dramatic sound effect creates an instant reward to movements, leaving an augmented yet compelling experience. Players can easily extend the fun by changing the sound files to drum beats, musical notes, and other sound effects. BlackBelt can potentially be used in motor skill rehabilitation.

Premiere at Superhero Custome Show at the 5th ACM SIGCHI Conference on Tangible, Embedded, and Embodied Interaction, Maderia, Portugal.

Collaborated with Ying-Jung Chen, Huaishu Peng, Kuanju Wu.

it’s all about display

This particular display caught my eyes in Ivan’s report from CES2010 :


“Experia phone from Sony Ericsson that had half transparent screen, which looked very nice, designy and conceptual.”

Now you can type from the back of your cell! I had always want to make a phone with keyboard on the back, since a lot of us don’t need to look at keyboard anyway (more true in China where we’re crazy about texting). Now with this translucent screen, you even get visual feedback where your finger is.
