document: pTHINC : a thin-client architecture for mobile wireless web Although web applications are gaining popularity on mobile wireless PDAs , web browsers on these systems can be quite slow and often lack adequate functionality to access many web sites . We have developed pTHINC , a PDA thin-client solution that leverages more powerful servers to run full-function web browsers and other application logic , then sends simple screen updates to the PDA for display . pTHINC uses server-side screen scaling to provide high-fidelity display and seamless mobility across a broad range of different clients and screen sizes , including both portrait and landscape viewing modes . pTHINC also leverages existing PDA control buttons to improve system usability and maximize available screen resolution for application display . We have implemented pTHINC on Windows Mobile and evaluated its performance on mobile wireless devices . Our results compared to local PDA web browsers and other thin-client approaches demonstrate that pTHINC provides superior web browsing performance and is the only PDA thin client that effectively supports crucial browser helper applications such as video playback .
