The Problem - NeedsNE1: Lack of designer/developer plug-ins, tools to support accessibility testingNE2: Minimisation of the need for real user testing during the planning/development phaseNE3: Accessibility assessment tools exist only for some application areas and only at the final stages of developmentNE4: The clear lack of accessibility support tools for non-ICT productsNE5: There is a clear lack of a realistic and immersive simulation experience during design/development of assistive technologiesNE6: There is a clear lack of simulation interface for multimodal interfaces targeting various disabilities
VERITAS Approach User Centered Design Iterative development and testing Virtual user models: Iterative development using feedback from the multisensorial platform Simulation models: Iterative development with feedback from real developers from the five VERITAS application sectors Iterative pilots: Feedback from real users Comprehensive risk analysis and mitigation strategy. Involvement of key industrial partners in all stages so as to6 ensure the applicability of the developed algorithms and systems

PERSONAS A persona is an archetypal user that is derived from specific profile data to create a representative user. A persona is more tangible, less ambiguous, easier to envision, easier to empathize with. A Virtual User Model10 describes an instance of a virtual user.
VERITAS PERSONAS11 E.g. PERSONA covering 90% of the disabled population w.r.t a specific disability
Multi-layered simulation platform VERITAS will support three levels of simulation Level 1: Low-level constraints satisfaction In this level the platform will examine whether the simulation models can be properly executed using the task models of the target user group Level 2: Semi-automated simulation also include several environmental variables. Execution of the simulation model of the virtual prototype with the target user group task models, including simulation of several environmental variables. Any inaccessible parts of the execution of the simulation model will be reported. Level 3: Physically-based simulation Is a grand research target on its own! VERITAS will focus on identifying parameters and specific degrees of freedom in the simulation that can be physically simulated and potentially result in evaluations that are not possible using Levels 1 and 2
