Thats a unique idea.You should consider the following idea to enhance your idea so that it would impact uniquely: Previous designs of variable friction touchscreens (VFTs) have utilized a single, banded mode shape for generating tactile sensations on the screen. This is done because the width of the bands in the mode can be tuned to be smaller than the typical human's fingertip, keeping users from perceiving the sticky sensations caused from nodal lines. While this has enabled the generation of a sticky or slippery effect at any single, instantaneous location, it does not leverage the most optimal mode shape at all locations and it does not enable localized tactile effects for multi-touch purposes. Ideally,  would like to be able to control the sensations locally on a VFT, meaning that  could create a desired effect at any desired location. Even longer term,  would like to be able to do this at multiple locations, simultaneously, enabling multi-touch haptically. ,  propose using superposition of multiple resonant modes to create richer tactile sensations and profiles for single touch and potentially enable some degree of controllability locally for future multi-touch use.  present our modeling and methods for implementing superposition, experimental validation of our efforts, and a user study demonstrating that this new approach does not suffer haptically from mode switching effects observed in prior work when switching from one single mode to another. The findings from this work establish a pathway forward for multi-touch VFT surfaces.
