  2. Outline • Mobile Web Browsers • Problem • Alternative: Thin Clients • Usability • Visual Comparison • Measurements • Conclusion

  3. Mobile Web Browser

  4. QuickTime™ and a TIFF (LZW) decompressor are needed to see this picture.

  5. FLASH VIDEO IMAGE

  6. Issues with Mobile Browsers • High quality pages mean.. – More Data Download – More Client Processing – Compatibility Issues • Application, Platform, Browsers, Standards – Requirement Issues • Flash, Java Applets, Javascript, Plug-in – Resize Issues – Language support

  7. Alternative: Thin Clients

  8. Thin Client • Leverage Server – High speed connection – More resource – Persistence • Allows – Heterogeneous display – Stateless client

  9. Thin clients vs Web • preserve software • rewrite applications investments for the web • no client applications • client browser and helper applications

  10. Thin Clients

  11. pTHINC applications high-level requests window system device driver raw pixels framebuffer

  12. pTHINC applications window system display updates virtual device driver input events

  13. pTHINC • Fast and Lightweight • Leverage and Virtualize display • Video support

  14. pTHINC protocol • copy • solid fill • pixmap fill • bitmap • RAW

  15. Usability Enhancements

  16. pTHINC Usage

  17. Visual Comparison QuickTime™ and a QuickTime™ and a TIFF (LZW) decompressor TIFF (LZW) decompressor are needed to see this picture. are needed to see this picture.

  20. Measurements

  21. Measurements • Test run on basic Web benchmarks • Variable conditions – PDA: Dell Axim x5, x51v QuickTime™ and a TIFF (LZW) decompressor are needed to see this picture.

  22. Web Latency QuickTime™ and a TIFF (LZW) decompressor are needed to see this picture. Latency measurement based on average page load time

  23. Video Results QuickTime™ and a TIFF (LZW) decompressor are needed to see this picture. Quality based on amount of data transferred

  24. Conclusion • Mobile Web Browsers can be improved • pTHINC: potential alternative – Increased visual performance – Better usability – Helper functions such as video
