HandWave is a wireless sensor that monitors relaxation level by measuring Galvanic Skin Response(GSR).

Existing GSR sensors require cabling for affective applications. The HandWave's
unobtrusive, wireless form factor provides for more natural readings. HandWave uses Bluetooth for wireless data transfer, making it possible to monitor the GSR data with a variety of devices for many different applications.

Currently, HandWave is used for biofeedback in games. On a larger scale, HandWave could be used to implement a dynamic sensor network involving dozens of devices, used to monitor the excitement of a crowd.
