Introduction: People with disabilities may need assistive devices (AD) to support in activity and participation and theories demonstrate that the environment can affect how such a device is applied by the end-user. Due to the design of the home environment, special challenges may arise in the application of mobility devices within the user’s home. Although the AD - activity chair supports the user in performing activities in the home environment, similar challenges in the usability are expected to arise. Currently, no documentation exists pertaining to how the user’s home environment can affect the usability of an activity chair.
Aim: To evaluate the usability of a VELA activity chair in the home environment.
Methods: A usability test for the activity chair was developed based on the HAAT-model and performed on a single real end-user, in addition to six healthy individuals. The test was performed in the user’s kitchens and the resulting data analyzed with thematic analysis.
Results: The activity chair supports performing activities in the kitchen however obstacles such as flooring and thresholds can affect its usability. The individuals also demonstrated challenges with operating certain functions.
Discussion: For the activity chair to ensure maximum usability for a given individual, both their specific needs and the existing home environment should be taken into consideration, with the ability to customize being beneficial. Thus, the process of the provision of such a device is also considered to have an impact on its usability by the end-user.
