1. A computing device, comprising:
- a display;
a touch screen for detecting on-surface user input;
a sensor subsystem for detecting off-surface objects; and
memory having instructions stored on it which when run on a processor, causes the processor to perform the steps of;
setting the sensor subsystem to a powered-on state, from a powered-off state, when a predetermined on-surface gesture is detected via the touch screen;
determining a compound gesture using a combination of the detected on-surface gesture and an off-surface gesture determined using the sensor subsystem by;
detecting an off-surface object using the sensor subsystem;
determining a position and a shape of said detected off-surface object;
matching the determined position with a set of reference zones and the determined shape with a set of reference poses to thereby determine an off-surface gesture state;
detecting changes in the determined position and shape of said detected off-surface object using the sensor subsystem;
matching said changes in the determined position with transitions between said reference zones and matching said changes in determined shapes with transitions between said reference poses to thereby determine a transition between off-surface gesture states; and
,instructing a user interface to provide feedback based on the compound gesture including the determined transition between off-surface gesture states.

Abstract
A computer device with a sensor subsystem for detecting off-surface objects, that carries out continued processing of the position and shape of objects detected in the vicinity of the device, associates these positions and shapes with predetermined gesture states, determines if the object is transitioning between gesture states and provides feedback based on the determined transition between the gesture states.
