Langner, Martin, Sanders, David, Tewkesbury, Giles, Zhou, Shikun and Haddad, Malik (2023) Human Machine Interaction Using Zero Force Sensing Switches Incorporating Self-adaptation. In: International Symposium on Biomedical and Computational Biology.

Abstract

A novel human machine interface is presented that ‘self-adapts’ to accommodate for changes in position between an operator and a non-contact sensor. Zero force sensing has been especially suitable for people with small amounts of movement force, making switch operation difficult or impossible. A common issue with existing switches concerned maintaining a workable operating position for a user. Testing of new “auto adapting” sensors demonstrated the viability of the approach and optical sensors provided a workable solution, but problems were encountered in strong light. Further work addressed this problem.
