Presentation Transcript

  1. Indycar TelemetryData Acquisition Interface University of Waterloo Systems Design SD 542 Danny Ho 97 140232 March 25, 2002

  2. Presentation Summary • Introduction to Telemetry • Functional Decomposition • Initial Design • 1st Prototype • User Feedback & Limitations • 2nd Prototype • Industry Comparison • Conclusions

  3. Objective of Telemetry • Ensure driver safety • Monitor vehicle performance • Use data history to adapt car to track 1st place finish !

  4. The Flow of Data Onboard sensors Radio transmitters Pit lane

  5. Functional Decomposition

  6. Initial Design

  7. Focus of 1st Interface • Functional Visual Basic for Application implementation • Simulate alarm conditions • Provide real-time monitoring scenario

  8. 1st Prototype

  9. User Feedback & Limitations • Alarm salience was adequate • Visual representation did not conform well to mental model • Graphical forms lacked frame of reference (scale) • Certain graphical elements were hard to notice

  10. Final Prototype

  11. Final Prototype

  12. Final Prototype

  13. Industry Comparison

  14. EFI Technologies

  15. PI Research

  16. Conclusions • Proposed system: • offers richer, more iconic representation of data • Provides better cognitive association • Improves upon salience and mental model • Industry systems: • more data intense • data display in the strictest sense • targeted towards expert engineers (experienced!)

  17. Q & A • How critical is alarming? • Shouldn’t experts know what to look at? • Analogical or Iconic? • Is industry software too bland?
