Persons with disabilities in our communities often find it difficult to achieve and maintain an independent and high quality of life. A significant cause of this issue is the challenge in independently navigating locations. Some prior studies investigated indoor navigation apps for one group of disabled users but few have addressed wayfinding needs of people with various disabilities simultaneously. The objective of this research was to design a friendly indoor navigation app for people with disabilities (FIND). The interface was evaluated and enhanced using a heuristic evaluation and focus group meeting with usability experts. The results were analyzed based on Molich and Nielsen’s usability principles and using a content analysis approach. The provided recommendations can be beneficial to improve the design of navigation apps for people with disabilities.
