Poster: Force feedback and visual constraint for drawing on a terrain: Path type, view complexity, and pseudohaptic effect

We evaluated stylus-based force feedback and a visual constraint alternative for marking paths on a terrain dataset. We further considered effect interactions with factors affecting task difficulty, including path difficulty related to contact geometry and indirect viewing. For example, the performance benefit of force feedback (relative to visual constraint) was minimal when the path lacked laterally-reinforcing geometry. We also show the visual constraint may generate a pseudohaptic effect: subjects report significantly more touch sense than for a no-force condition.
