HAIL gmail: Email with hierarchical adaptive interface layout

Document Type

Conference Paper


For users with disabilities using mouse-replacement devices, we propose an email interface that adapts to the abilities of the user. The application implements HAIL (Hierarchical Adaptive Interface Layout) and provides an interface using Google’s Gmail API. The interface was intended to be simplistic and user-friendly, with large, color-coded buttons, an uncluttered screen, and functional access to the user’s inbox. Through the two main windows, the user is able to read and compose emails. We tested the application with the mousereplacement interface “Camera Mouse”, which uses a web camera on a computer to track the user’s face to control the mouse pointer. The characteristics of HAIL Gmail were implemented with the strengths and weaknesses of Camera Mouse in mind. Initial testing of the HAIL Gmail included several subjects without disabilities. Participants were able to complete the tasks and stated that the interface was relatively easy to use. These subjects also offered some constructive feedback in the form of possible improvements such as modifying how to compose emails. After the initial stages of HAIL Gmail, we plan to extend the capabilities of the interfaces to the point where we can deploy it for public use.
