A Functional Optimization Based Approach for Continuous 3D Retargeted Touch of Arbitrary, ...
summary
Presents a software method that computes a 3D spatial warp by solving a functional optimization (converted to a PDE) to continuously remap touch between arbitrary physical and virtual boundaries so fingertip contact stays coincident; demos include remapping a rectangle to a circle, a coffee cup to a tea cup, and a plane into a corner and run on an HMD with OptiTrack. A lab study (nine shape-pair trials per remapping type) shows max smoothness (lambda=0) yields the lowest perceived position and movement mismatch, works well for scale/size changes but less so for sharp edge/corner cues; method guarantees max displacement on the surface and keeps it below JND when configured.
