PALLA: a Spherical Wireless Input Device for Leisure Activities
PALLA is a spherical wireless input device that we developed for experimenting with motion sensing and physical interaction in leisure activities.
It is capable of sensing its own complete orientation with respect to the external world, it can measure its altitude with a precision of about 10 centimeters, when rolled on a planar surface like a table or the floor, its rolling path can be tracked precisely, it can detect taps and double taps as well as their magnitudes, moreover it can also detect hand proximity and provide simple visual and vibration feedback.
In order to assess the acceptability of PALLA, we developed a simple video game, called PandaGolf. The video game uses the device as part of a tangible user interface to engage players at the physical level by exploiting their perceptual-motor skills.
The game has been tested with various senior players. The results have been positive and encourage us to continue our research with the device.
