pTHINC Better web browsing on your mobile device Joeng Kim Ricardo Baratto Jason Nieh Columbia University, USA

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

Mobile Web Browser

VIDEO FLASH IMAGE

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

Alternative: Thin Clients

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

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

Thin Clients

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

virtual device driver pTHINC applications window system display updates input events

pTHINC Fast and Lightweight Leverage and Virtualize display Video support

pTHINC protocol copy solid fill pixmap fill bitmap RAW

Usability Enhancements

pTHINC Usage

Visual Comparison

Measurements

Test run on basic Web benchmarks Variable conditions –PDA: Dell Axim x5, x51v

Web Latency Latency measurement based on average page load time

Video Results Quality based on amount of data transferred

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