Usability Testing of Repositionable and Customizable Locking Mounts with Rehabilitation Professionals

Emilie Sundberg, Dianne M. Goodwin


New mounting devices under development were tested to determine how easy it was to discover, with no instructions, how to operate the mount and set it up for a consumer with a disability.  The new mounting device includes a feature whereby the mount will lock in a specific position according to an individual’s needs.  Assistive technology specialists, those expected to set up assistive devices for their clients, were recruited for usability tests at a stage in which two different lock-setting interfaces and consumer controls had been developed and incorporated into working prototypes.  Three configurations were tested to compare the usability of the interfaces.  Statistical analyses found significant differences between the lock-setting interfaces in ease of operation and ease of setting the lock.  The findings influenced changes in the design to improve the usability for those setting up the mount.

Disney produced a television show in the mid 1990s called Gargoyles. It's a great show and I'm a big fan. A few years ago Disney started to release the show on DVD. The last release was of season 2, volume 1. That was two years ago. Volume 2 has not been released. Why? Poor sales. So if you should find yourself wanting to support my work, instead I ask you pick up a copy of season 2, volume 1. It's a great show and you might find yourself enjoying it.
