Abstract
The Cybathlon is a non-profit competition of ETH Zürich for assistive devices. The goal of this competition is to challenge existing technologies and develop assistive technologies suitable for everyday use with and for people with disabilities. Currently, arm prosthesis users have to look at their hand in order to adjust finger position and grip force. Amputees wish to reduce the visual attention necessary during grasping. Resulting in the research question: Is it possible by means of a proof of concept with commercial sensors to write an algorithm through which the shape and hardness of a three-dimensional object can be recognized to win the Cybathlon 2024? Two participants were asked to recognize 12 objects while wearing a glove with three force sensors, without seeing the objects. The non-zero mean, non-zero median, maximum values, and contact counts were calculated and plotted in box plots to visually assess the differences. However, based on this visual assessment it remains unclear whether these features contain sufficient information to identify the individual objects. Due to the fact that multiple sensors broke down during the tests, and because of time restrictions of this project it was not possible to repeat the tests, the results are not reliable. However, this pilot experiment gives important information for follow up experiments.
