L O G L I N E L O G L I N E TAXY is a reachability feature to facilitate one-handed interaction with smartphones. Once activated by a fl ick gesture, TAXY generates a new virtual cursor, determined by the user’s thumb position and the current values of the accelerometer. Distant elements can easily be reached - even on a large screen.
