Hearing Aid Glasses

The aim of this study was to design a hearing aid smart glasses for hearing impairments. The product aimed to help hearing-impaired people identify the direction of sound in daily scenarios. In this project, I practiced how to evaluate a design product during and after prototyping. Since the time limitation, our prototype is more focused on the function of lights and the multi-touch control components instead of the sound detection function. In other words, the prototype was not fully functional. Thus, I chose an evaluation method that does not necessarily

evaluate the technical capability, which was heuristic evaluation. During the heuristic evaluation, we reflected on the prototype based on existing frameworks or checklists. I made a video including the poster made by another teammate to demonstrate the capabilities of the product by showing the wizard-of-oz scenarios. I also adapted a checklist based on existing validated ones (e.g., Blackwell and Green’s Cognitive Dimensions of Notation) to make it more suitable for our situation. I also scripted the user test plan which includes an overview of the design, an interaction section with the wizard of oz prototype, and an evaluation questionnaire.

In this project I...

• Defined the functions of the hearing aid smart glasses

• Edited the video demonstration of the prototype

• Planned and conducted heuristic evaluation

• Organized user test and scripted the questionnaire

• Wrote the evaluation section in the report

• Tools: Adobe Premiere
