The design of color detector device for visually impaired people

Abstract

This study was conducted to create a design of color detector device that can meet the needs of people with visual impairments. In the early stages of research, interviewswas held to determine the difficulties that were being faced by the visually impaired when identifying color difference. Further interviews were conducted in order to obtain their further needs to the design of a color detector device. The next thing to do was to determine the importance rating of each need that was identified. Based on the importance rating of the needs, some design concepts were generated by using some combination tables. Having made various design alternatives, concept selection was conducted by involving users and designers. Anthropometric data was used for determining the dimensions of the selected design. The device that was designed was a color detector device with a voice output. Final prototype was then made using a variety of electronic components, including a color sensor, microcontroller, and chip recorder. Based on the final prototype, a test was held to obtain the user’s response on its function and design.
