Study purpose and participants
The research examined how wheelchair users interact with urban environments while using mobile navigation technology. It involved nine manual wheelchair users in Quebec City, Canada: seven men and two women aged 21 to 61. The researchers sought to identify missing information in route instructions and determine which components could support adapted navigation.
Field-study approach
Participants followed a predefined route using Google Maps while wearing eye-tracking glasses. Researchers recorded their navigation, conducted semi-structured interviews during the journeys, and collected participants’ route descriptions afterward. Analysis considered hesitation, confusion, stops, navigation errors, visual behavior, and participants’ perceptions of the technology and surrounding environment.
Information gaps identified
The findings indicated that adapted instructions should include more explicit street-crossing and continue-straight actions. Researchers also emphasized alerts concerning accessibility and safety issues, along with recognizable environmental objects that can help users orient themselves and confirm their routes. The study concluded that richer instructions may help users anticipate accessibility conditions and attend more to their surroundings instead of repeatedly checking a phone.
