User scenarios proposed during the workshop by the workshop participants to challenge device independence authoring techniques.
Rich multimedia content (e.g. SMIL) user, video conferencing user
PDA or limited device
Mobile, no wires, must consider low bandwidth, data loss, low connection reliability, etc. In this environment an intermediary proxy or content provider exists.
Interact with a multimedia presentation, react and interact with the presentation; e.g. switch between conferences.
Architecture calls for proxy or server-based adaptation.
Email user
PC; in car voice system; phone; PDA
Multiple environments: office; car; sidewalk; home
Read email, reply, etc. While maintaining email state as the user puts down one device and picks up another. Device capabilities may limit what can be done, e.g. only allow reading of email (not replying) when in car and using voice interface. Application must be device aware to omit irrelevant functions.
Consistency of application across multiple devices, application session migration from one device to another.
Average consumer
Interactive TV as view device; PDA or phone or intelligent remote control as control device.
Home, living room
Buy something they see on TV by entering from data on a PDA/phone/remote control
Doctor and radiologist
PDA and PC
Remote, mobile location (doctor) Hospital (radiologist)
Radiologist is sending X-ray photos to doctor, from PC to PDA. Radiologist needs to ensure that the doctor is viewing the same image. Color depth/temperature, resolution, etc. might differ between devices. The data is very critical.
Issue is consistency of inteface to a very fine-grated level. Adaptation cannot affect data representation.
Emergency response application
Doctors, nurses, trainees
PC, PDA's
Hospital, doctor's home.
Take care of patients. Doctors and nurses have different activities. Nurses can do a subset of what doctors can do. Requires authentication and work of trainees needs to be checked/validated by doctors. Diagnostic system can be accessed by doctors through a voice interface to improve productivity. Doctors need access to lab results and treatment activities and results. Nurses and doctors must coordinate their activities.
Role is part of the context. Is adaptation feasible in an emergency situation? Question of timeliness of information as well as interaction time requirements. Also, synchronization issues.
