  1. Design Of A New PumaPaint Interface And Its Use in One Year of Operation Roger Williams University Bristol, RI ICRA2004 April 28, 2004

  2. What is PumaPaint? • Online robot that does one thing • Java interface to let users do it • Demonstration of remote telerobotic control • Not a plotter • WWW site for creating and receiving a physical artifact

  3. Origins • Wilkes University • 1998-2000 • Roger Williams University • 2002-Present • Roughly 40,000 users to date

  4. The Java Interface • Original Interface • English text predominant • Somewhat flat, gray • Not entirely intuitive

  5. This project • Develop a new interface using Java2/Swing • Move from English text to icons • Provide a warmer feel • Undergraduate independent study for two semesters

  6. The New Java2 Interface • OK, it’s still kind of flat and gray

  7. Some key improvements • Camera windows • A. Ryan Tiebout • WinTV card • CGI interface and controls • Near live video

  8. Some key improvements • Context sensitive mouse Brush Colors

  9. Some key improvements • Animated buttons • Grayed out when invalid • Shows current color

  10. Some key improvements • Slider animations

  11. Unintended consequences • Slider animations can be confused with actions • Return “Dip” button • Do you move the slider to paint? • May be misleading indication of contact

  12. One year usage Source: httpd log August ’02-August ‘03 Roughly 2500 people connected up About 40% of potential users did not have Java2 Of those, 14% apparently bothered to obtain the plug-in and return to download the interface

  13. What did they do with it? • Typical canvas • Lots of text • Lots of scribble

  14. What did they do with it? • Some nice pieces • Some mailed to users • Not all

  15. Recent Phenomenon • Dedicated vandal

  16. Recent Phenomenon • Metronome like strokes • Automated issuance of commands? • Hundreds of hours connected

  17. Recent Phenomenon • Likes to tear down the paper • Metronome strokes on easel AOL user from New Jersey Asked for canvases but ignored repeated requests to explain techniques or motivation

  18. Summary • Site continues as a vehicle for undergraduate projects • Online 5 years and counting* • Still interested in paintings • Dedicated vandal something new • Currently developing 3D manipulation using anthropomorphic hands to model clay
