Summon and Select: Rapid Interaction with Interface Controls in Mid-air

Abstract : Current freehand interactions with large displays rely on point & select as the dominant paradigm. However, constant hand movement in air for pointer navigation leads to hand fatigue quickly. We introduce summon & select, a new model for freehand interaction where, instead of navigating to the control , the user summons it into focus and then manipulates it. Summon & select solves the problems of constant pointer navigation, need for precise selection, and out-of-bounds gestures that plague point & select. We describe the design and conduct two studies to evaluate the design and compare it against point & select in a multi-button selection study. The results show that summon & select is significantly faster and has less physical and mental demand than point & select.
