Does a Multi-Layer Display Reduce the Effect of Non-Target Flankers?

Abstract

Pointing movements to targets may be influenced by non-target flankers. A Multi Layered Display^TM (MLD) was used in an attempt to reduce any distracting effects of flanking targets. A ‘response vector model’ predicts movements away from highly salient flankers, while a ‘response activation model’ can predict movements towards. Participants were 14 skilled computer users who moved a computer cursor using a mouse to virtual targets. Kinematic analysis revealed significant effects consistent with the response vector model. Separating target and flanker separation using the MLD reduced the distracting effects of flankers upon the early “planned” part of cursor trajectories but not the latter part of cursor trajectories.
