Pointing without a pointer

We present a method for performing selection tasks based on
continuous control of multiple, competing agents who try to
determine the user’s intentions from their control behaviour
without requiring an explicit pointer. The entropy in the selection
process decreases in a continuous fashion – we provide
experimental evidence of selection from 500 initial targets.
The approach allows adaptation over time to best make
use of the multimodal communication channel between the
human and the system. This general approach is well suited
to mobile and wearable applications, shared displays and security
