Paper Summary:

This paper looks at the comparison of two devices for low-vision reading aids. The magnification devices include an existing technology, Close Circuit Television Video Magnifiers (CCTVs) and a new technology, myReader.

The technologies were evaluated with 42 participants from three audience groups, including:

• Participants with low-vision who currently use CCTVs (experts)
• Participants with low-vision who do not use CCTVs (novices)
• Participants with normal vision from an age-matched group (control group)

The study was conducted in two separate visits to participants' homes. Participants were asked to complete a demographic questionnaire, were instructed in the use of both machines until they reached a certain level of competency, completed a 10-minute reading test, and were interviewed at the end of the session about their experiences.

In addition to being video recorded, participants' actions were logged including: reading speed, comprehension, errors, perceptions about physical requirements, and system satisfaction. The results showed that myReader resulted in an 18% increase in reading speed (although experts were actually faster on the CCTVs) and had similar comprehension rates as the CCTVs. In addition, 74% of participants preferred the myReader.

In designing this product, the project team looked at the sociological, ideological, psychological and physiological requirements of these user groups. Based on the user evaluation, the authors believe that many of the needs identified have been met with the new technology.

The authors plan to launch a four-week trial with low vision users before releasing the product in 2004. During this evaluation, users will be asked to use the machine prior to the four-week trial and keep a diary of use. At the end of the trial, a summative evaluation will be held to compare improvements in performance after using the system for an extended period of time.
