Condor user interfaces for mobile terminals Javier Vales Alonso (jvales@delta.ait.uvigo.es) Javier González Castaño (javier@ait.uvigo.es) Universidad de Vigo (Spain)
Outline • Goals • Mobile internet & wireless technologies • Portable devices and their hierarchy • Web system architecture • WAP system architecture • Examples • Conclusions & future work
Goals • Integrate Condor in the mobile internet world. • Allow different levels of user accessibility. Or: ¿what is missing in Condor to face the mobile Internet?
Mobile Internet • Internet technologies and services for mobile devices. • Mobile-Internet is driven by the convergence of: • Wireless technologies • Portable devices
Wireless technologies • They will enable easy interconnection of a wide range of portable computing devices. • Present: 2G systems (GSM, IS-95). • Incoming: Wireless LAN (IEEE 802.11), Bluetooth, HomeRF, LMDS, 3G systems (UMTS).
Mobile devices • (Wireless) laptops (first mobile solution) • PDAs (Palm pilot, pocketPC,...): user interface with limited capabilities. Handwriting recognition. • WAP-enabled mobile phones: user interface even more limited. • Next: Wearable computers (less comfortable, need goggles). Speech recognition.
Condor Condor • Program tuning: • Final-stage programming utility • Small modifications in source code • Program generation • Check queue status • Remove, hold & release jobs • Submit new jobs • Alarm on job finish Usability • Check queue status • Remove, hold & release jobs • Submit new jobs • Program tuning +
Layer implementation • PDA layer is implemented as a web service. This has many advantages: • Familiar interface. • WAP system implementation is a subset of PDA system implementation (compatibility & reutilization) • Almost all PDAs have web browsers (platform independence) • WAP layer uses WML browsers.
Web system architecture HTTP Server 1. Operation request 3. Non-Condor command mapping 2. Condor command mapping CGI CGI HTML HTML Condor-enabled system Non-Condor commands Condor commands
WAP system architecture HTTP Server WAP G A T E W A Y 1. Operation request 3. Non-Condor command mapping 2. Condor command mapping CGI CGI WML WML Condor-enabled system Non-Condor commands Condor commands A L A R M
Conclusions & future work • Definition of usability-hierarchy for mobile internet devices • Assumption: Cell phone/PDA units everywhere • Remote execution of most functions • Other paradigms: Interface servers (X-Windows, Citrix)?
