Analysis of Tactile Map Reading

This project presents a comprehensive analysis of a prototype tool designed for visually-impaired users to read tactile maps effectively. Led by analyst Amy Lobben, the tool tracks finger movements over tactile map overlays, allowing for data visualization of interactions. The prototype established the feasibility of tracking multiple fingers using video and a finger with a tablet. Various analysis and display methods were discussed, leading to the creation of an initial heat map display. This project aims to provide insights for future teams to build upon in improving tactile map navigation.

Presentation Transcript

  1. Analysis of Tactile Map Reading Tablet, Visual and Signal Teams for CIS 423/510

  2. For analysts like Amy Lobben who research how visually-impaired users navigate tactile maps. Provide a tool capable of: tracking finger movements over a tactile map overlay visualizing the data received during tracking Who is this Tool for and Why?

  3. Overview First Prototype:   A foundation for new requirements, design and implementation details Accomplishments: • Established feasibility of tracking multiple fingers with video • Established feasibility of tracking a finger with tablet • Combined video and finger tracking data • Created one example data display (heat map) • began discussion of what kinds of analysis and display methods are useful • Built a "baseline" implementation of all components • allows future teams to pick individual components to enhance or replace 

  4. Teams Tablet Team: Tracks a single finger using a tablet and pen device Visual Team: Tracks multiple fingers from a video source Signal Team: Visualizes data received from Visual and Tablet Team into graphs representing finger movements

  5. Presentation Overview Tablet Team Presentation Visual Team Presentation Signal Team Presentation Live Demonstration Questions and Feedback (will follow each presentation) Setup during combined Visual and Tablet Team testing
