Technical Evaluation of Earswitch Phase A

The goal of this study is to test the Earswitch device in both participants with and without assistive technology (AT) needs. The main aim is to determine how robust the Earswitch is in detecting voluntary eardrum movements (known as ear rumbling) and see how well the Earswitch fits with other assistive technology. To do this, participants will be asked to wear the Earswitch device and voluntarily contract their TT to complete a series of tasks shown on screen and/or explained audibly. Participants will be asked to complete questionnaires to understand their opinions about the effectiveness, usability, and comfort of both their current device (if applicable) and the Earswitch. This feedback will be invaluable in developing the Earswitch.
