Abstract
Techniques are provided for a gesture device to detect a series of gestures performed by a user and execute corresponding electronic commands associated with the gestures. The gesture device detects a gesture constituting movements from a user in three-dimensional space and generates a confidence score value for the gesture. The gesture device selects an electronic command associated with the gesture and compares the electronic command with a prior electronic command associated with a prior gesture previously detected by the gesture device in order to determine a compatibility metric between the electronic command and the prior electronic command. The gesture device then adjusts the confidence score value based on the compatibility metric to obtain a modified confidence score value. The electronic command is executed by the gesture device when the modified confidence score value is greater than a predetermined threshold confidence score value.
