Magnetic Cursor: Improving Target Selection in Freehand Pointing Interfaces

摘要: We present the magnetic cursor, a technique that aims to make distant freehand interaction with targets easier in large-screen public display applications. The cursor automatically warps selectable object is close by, moves slower while on object, and shows relative location visually user. Two designs of were compared snap-to-target 19 participant user study. Results indicate design weaker magnetism effect outperforms other techniques terms target selection efficiency. Subjective feedback indicates meet participants' expectations for pointing are preferred unassisted stronger magnetism. Our findings suggest visual short, static activation threshold can help users maintain within active motor space target, especially when several situated proximity.
