Requirements of Transport Information Service and Route Guidance Service for Older Adults
This study aims to acquire the requirements of older adults for transport information service and route guidance service. The objectives include: 1) to understand the difficulties of older adults when they take a trip and find a route; 2) to find out necessary and unnecessary functions; 3) to recommend what functions should be added. Previous studies showed older adults had poorer navigation performance in terms of longer task completion time, more errors and more disorientation. Multimodal presentation could help them construct landmark knowledge. 9 older adults aged between 68 and 75 participated in two focus group discussions. The discussion procedure included five major sections: the warm-up and introduction, use case description, individual assessment, group discussion and feedback. After detailed description of each function of the two services, they individually rated its necessity. Then they discussed with others about whether they need certain function and what functions should be added. Results show that, first, pre-trip information and real-time positioning function are perceived very necessary. Second, older adults tend to rely on landmark. Multimodal presentation of landmark was desired. Third, additional functions suggested by older adults were collected, such as information about possible risk. Finally, older adults were more likely to use navigation aids in a short-range trip instead of a long-range trip.
