MARS Bag
The MARS
Bag is a prototype for wearable mobile interaction and
communication. Carried like handbags, MARS bags recognise
both the movements of the wearer and those of people
nearby. They translate the movements into sound.
The principle
of the motion sensing system used is that of the Theremin,
an electronic instrument built in the 1920s. The Electronic
Field Sensor (EFS), on which the MARS Bag's interface
is based, is a modern digital version of the Theremin.
The EFS permits navigation in virtual space with simple
and immediately understandable hand gestures.
The advantage
of electronic field sensing is its independence of object
surface texture, light conditions and other factors
that limit video tracking. Moreover, electric field
sensors are cheap. These factors make electric field
sensing a promising solution for navigation and interaction
in virtual environments.
