Designers and system analysts have long struggled to extract and repurpose data from user research by laboriously presenting content in the form of storyboards, behavioral-type personas, or journey maps. An alternative is to convey insights from user research through scenario-based personas that represent user research data through storytelling. This provides a more streamlined way to convey data rather than character-based personas; however, scenarios are effortful for developers to articulate and envision. In this work, we empower assistive technology development teams to access authentic user experiences with scenario-based personas through tangible and digital artifacts. Scenario-based personas were used for conveying the results of a user analysis study for color identification mobile applications for people with visual impairments. We developed scenario-based personas for persons with impaired color vision based on the main contexts identified in user research studies. The method combines personas depicted in silhouettes of people with impaired color vision and scenario contexts that capture the place and activities. Silhouettes were used in the artifacts to reduce the bias that a face often generates in persona-based scenarios. Preliminary findings suggest that scenario-based persona tools were effective in describing the stories and context behind why a person with a visual disability would consider a color identification application. Through this method, scenario-based personas were able to foster understanding of the application's target user population by showing their main contexts of using these mobile applications and create playful and tangible artifacts to capture and convey such user information to designers and developers in the Humanistic Co-Design community. Methodological considerations for using scenario-based personas in user research will be discussed.

Low contrast between text and background and its effect with low vision is relatively well-understood. Many tools exist for helping web designers check contrast limits. Most of these tools identify contrast problems but give limited advice on how to rectify the problems. Moreover, website accessibility audits reveal that insufficient color contrast still is a recurring issue in practice. A framework was therefore developed that automatically proposes color adjustments to problematic text-background color pairs on web pages. These suggestions adhere to contrast requirements and are aligned with the visual design profile. The framework allows the developers to visually inspect the suggestions and amend color definitions in projects.
