Product Accessibility Evaluation using Virtual User Models

This demonstration includes several cases of simulating the behavior of avatars interacting with virtual product prototypes. These prototype scenarios include the ergonomic evaluation of car interior designs, motorcycle dynamics evaluation, wheelchair navigation, virtual home environments accessibility testing, as well as cognitive and vision impairment simulation of interaction with graphical user interfaces.

User Model Generator (VerGen)

This application tool is used by VERITAS developers and designers to create a new Virtual User Model (VUM) to be used by the simulation core.

3D Editor (VerSEd-3D)

The 3D editor is used to prepare a virtual scene for simulation. The simulation preparation takes as input a 3D cad file and adds Designers use the Interaction Adaptor tool in order to create simulation model and interaction adaptation of a 3D design based on the simulation and task models of an application area and finally export the adapted -for interaction- 3D scene to the simulation core.

3D Core Simulation Viewer (VerSim-3D)

The 3D core simulation viewer is the tool used to run immersive simulations in order to test 3D products (for example chairs, cars, office spaces). A virtual scene, a scenario and a Virtual User Model (VUM) are loaded first. The simulator reports failure/success rates and duration needed by the virtual persona to complete the set of tasks described in the scenario.

GUI Capturer and Editor (VerSEd-GUI)

This is an application designed A) to capture the user’s behaviour while using the GUI of an external application and B) to let UI designers prepare a simulation. The final outcome is a properly prepared scenario file, ready to be used by the GUI simulator.

GUI Core Simulation Viewer (VerSim-GUI)

The GUI core simulation viewer is the tool used to run desktop simulations in order to test application GUIs (for example websites, mobile device interfaces, dektop applications). After initialization of the testing application, a scenario and a Virtual User Model (VUM) are loaded before the simulation. During scenario execution, a virtual filter is applied to the screen to simulate the visual impairment, an audio filter is applied to the speakers to simulate acoustic impairments and the cursor motion on the screen is reproduced by the simulator according to the motor impairments carried by the VUM. Finally, the tool reports failure/success rates and duration needed by the VUM to complete the set of tasks described in the scenario.
