Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Many powered wheelchair users find that collision free driving presents a significant challenge to confident and safe driving. In some cases so much so that the user will not drive their chair in some environments.

Interviews with users in the EDUCAT project confirmed that users had problems driving safely and confidently in a confined space, passing through doorways or down narrow corridors and when reversing.

Therefore the goal of this stage of the project is to improve the quality of life of the powered chair user by developing an obstacle alerting system which will help improve their confidence and safety in driving.

This was to be achieved by asking expert users to provide feedback on the impact and usefulness of providing information about the presence and location of obstacles in the vicinity of their powered wheelchair.

There are two aspects to this.

1. User assessment of the usefulness of the obstacle alerting feedback. This will include user evaluation of the value of the different modes of feedback - audio, visual and haptic - and how best to adapt these to the range of driving environments and driving speeds. And what level of control the user requires to select and deselect these options.
2. Monitoring the user's driving patterns with and without obstacle alerting -using the Stage 1 recording device.

The analysis of this data, and feedback from the Users and carers will inform the development and design of the obstacle alerting system.

Because of the COVID-19 pandemic the trial could not be carried out with powered wheel-chair users participating as they represented a clinically vulnerable part of the population. The trial was, therefore, adapted and carried out with adult non-wheelchair users.
