Several enhanced pointing techniques aim to reduce the Fitts' law targeting distance by providing multiple target trajectories in the hope that a shorter path is available. However, these techniques introduce a search or decision component to pointing -users must examine the alternatives available and decide upon the trajectory to use. We analyse these difficulties, present a methodology for examining them as well as other behaviour issues, and report empirical results of performance withdoi:10.1145/1978942.1979067 dblp:conf/chi/QuinnCRD11 fatcat:fmtq24zg3fch3kw4gkmiadeu5y
