Abracadabra employed magnetically driven input techniques to small mobile devices.
Abracadabra employed magnetically driven input techniques to small mobile devices where the user, with a magnet mounted on the finger, perform interactions around the device. A magnetometer sensed the changes in the magnetic field and interpreted such changes as interaction inputs.
* Most previous sensing techniques have required either direct manipulation (e.g., buttons, touch screens), or at least line of sight (e.g., ultrasonic range finding, infrared proximity , vision systems ).
* Writing tips:
** Their ability to be wireless and unpowered gives Abracadabra a unique edge over other a number of other spatial input methods.
** The success of Apple’s iPod, … In response, we built….
* Overall it’s a blueprint for UIST notes;
* Dan Olsen: “If I can fit my entire PC in a cubic inch, how will I interact with it?”. A question in contrast: “If I inflate my one PC to a room-sized space, how will I interact with it then?”
