ABSTRACT
Physical buttons provide rich force characteristics during the travel range, which are commonly described in the form of force-displacement curves. These force characteristics play an important role in the users' experiences while pressing a button. However, due to lack of proper tools to dynamically render various force-displacement curves, little literature has tried iterative button design improvement. This paper presents Button Simulator, a low-cost 3D printed physical button capable of displaying any force-displacement curves, with limited average error offset around .034 N. By reading the force-displacement curves of existing push-buttons, we can easily replicate the force characteristics from any buttons onto our Button Simulator. One can even go beyond existing buttons and design non-existent ones as the form of arbitrary force-displacement curves; then use Button Simulator to render the sensation. This project will be open-sourced and the implementation details will be released. Our system can be a useful tool for future researchers, designers, and makers to investigate rich and dynamic button"s force design.

Button Simulation and Design via FDVV Models
CHI '20: Proceedings of the 2020 CHI Conference on Human Factors in Computing SystemsDesigning a push-button with desired sensation and performance is challenging because the mechanical construction must have the right response characteristics. Physical simulation of a button's force-displacement (FD) response has been studied to ...
Press'Em: Simulating Varying Button Tactility via FDVV Models
CHI EA '20: Extended Abstracts of the 2020 CHI Conference on Human Factors in Computing SystemsPush-buttons provide rich haptic feedback during a press via mechanical structures. While different buttons have varying haptic qualities, few works have attempted to dynamically render such tactility, which limits designers from freely exploring buttons'...
Neuromechanics of a Button Press
CHI '18: Proceedings of the 2018 CHI Conference on Human Factors in Computing SystemsTo press a button, a finger must push down and pull up with the right force and timing. How the motor system succeeds in button-pressing, in spite of neural noise and lacking direct access to the mechanism of the button, is poorly understood. This paper ...
