Creating Virtual Prototypes for Adaptive Media Devices: Usability and Accessibility Considerations

This document explores the development of virtual prototypes for various media devices, including PDAs, wearables, desktops, phones, and even innovative inputs like toasters. It discusses key issues such as media convergence, accessibility of information, user interface adaptation, and the importance of device independence according to W3C standards. By addressing context awareness, augmented reality, and clean interfaces that separate UI from browser logic, the paper emphasizes how to adapt presentations and stylesheets for different devices while supporting XML adaptation for a seamless user experience.

  1. .:Virtual prototypes:. Juha Vierinen <jvierine@tml.hut.fi>

  2. -=:Issues:=- • Media Convergence • Devices with different constraints and context of use • Accessibility of information • Sanity of information • User Interface Adaptation

  3. -[ Devices ]- • PDA, Wearable, Desktop, Phone, TV ... Toaster? • New innovative Input / Output methods • Context Awareness, Augmented Reality.

  4. -:> In XSmiles <:- • Clean interfaces, which separate UI from browser logic • Possibility to add new devices • Support for XML adaptation (CC/PP & XSL)

  5. oO Virtual Devices Oo • Different configuration for each. • Ability to switch betwean windows • Stylesheet selection logic • Physical buttons on screen

  6. öÖ Accessibility Öö • W3C Device Independence specifications • Separate presentation from content. (XML + XSL stylesheet for each device) • CC/PP to relay capability information to the server. • Prototype server which understands CC/PP

  7. O.o Examples o.O • Three different virtual devices: PDA, DigiTV, and Phone. • Work still (always) in progress. E.g. XForms UI widgets for different devices.
