Abstract: The present disclosure provides for one-handed, touch-free interaction with smartwatches. An optical sensor in the smartwatch detects a user's hand and finger movements on the arm wearing the smartwatch. The gesture detection and recognition approaches in this design are lightweight and efficient to operate on small devices.
