This work, Stylus Assistant, proposed two designs of actuator array system, DynaFrame and DynaBase, to realize dynamic physical constraints on portable displays for facilitating stylus input.

DynaFrame: Around-display constraint

DynaBase: Back-of-device constraint

User interface with inverse kinematics and path recording

I designed and fabricated the case and support using a laser cutter and 3D printers. I also took part in controlling the servo motors using Processing.
