    • 1. Non-visual Presentation of Graphs Using the Novint Falcon Reham Alabbadi, Peter Blanchfield, and Maria Petridou University of Nottingham, School of Computer Science11 July 2012 & IT
    • 2. Objectives Introduction Motivation The Falcon Graph (Implementation, testing, and results) ConclusionThe University of Nottingham Reham Alabbadi, 2012 2
    • 3. Introduction The Falcon Graph Interface - Haptic interface - Enable visually impaired individuals to access computer-based visualisation techniques - Novint Falcon display (www.novint.com) - Connected to spreadsheet systemThe University of Nottingham Reham Alabbadi, 2012 3
    • 4. Motivation The importance of graphs and diagrams Blind individuals are still deprived from accessing some certain types of information Alternative formats available - Textual descriptions (Approximately 10-20% know how to read Braille (Yu, Ramloll, and Brewster, 2000) - Tactile drawings (e.g. Swell paper) - Audio sounds - Haptic displays (e.g. The PHANToM, CyberGrasp, haptic mouse)The University of Nottingham Reham Alabbadi, 2012 4
    • 5. The Falcon GraphThe University of Nottingham Reham Alabbadi, 2012 5
    • 6. The Falcon Graph (Implimintation)The University of Nottingham Reham Alabbadi, 2012 6
    • 7. The Falcon Graph (Testing) Subject Visual impairment Residual Vision Experience with the Novint A Congenitally blind No Yes B Congenitally blind No Yes C Congenitally blind No Yes D Low vision Used No E Blind No NoThe University of Nottingham Reham Alabbadi, 2012 7
    • 8. The Falcon Graph (Results) Identifying and locating the graphs was less accurate than perception of basic models Pie Chart - Vibration was helpful to distinguish different pieces of the pie chart Bar Chart - Identifying the chart was the most difficult task - The size of the bars was small - The gap between the bars made it difficult to navigate - Vibration effectThe University of Nottingham Reham Alabbadi, 2012 8
    • 9. The Falcon Graph (Results) Line Graph - The lines were identifiable (increasing or decreasing) - Small graphical features of the lines made it difficult to navigate - Very difficult to find understand intersecting line graphs Surface effect - magnetic and vibrationThe University of Nottingham Reham Alabbadi, 2012 9
    • 10. Conclusion The Falcon Graph is a convenient interface in which a virtual environment presentation is connected to a well known commercially available spreadsheet system such as Microsoft Excel It takes into consideration two crucial factors - the availability and affordability of the current displaysThe University of Nottingham Reham Alabbadi, 2012 10
