Accessible UI Design and Multimodal Interaction through Hybrid TV Platforms: Towards a Virtual-User Centered Design Framework
نویسندگان
چکیده
We report on work towards an architecture that incorporates accessible design methods, guidelines and support tools for building and testing adaptive and accessible user interfaces (UI) for users with mild impairments. We especially address interaction constraints for elderly people, both during application design time and at run time, targeting on hybrid TV platforms. The functional principle of our architecture is twofold: At runtime, it lets users interact with hybrid TV applications through an ensemble of accessible UIs that cover different input and output modalities and are jointly adapted via user profiles and real-time feedback. At design time, it allows developers to re-use UIs and representative user personas in simulating the effect of the UI modalities on different impairments.

Multimodal Software for Affective Education: UI Design
This paper focuses on interaction design for multimodal software in affective education. We suggest how multimodal systems can help us, and give a proposal for how to design the systems. These are demonstrations of how the MADE framework can be applied to well-known design techniques. Our goal is to come up with human-computer interaction (HCI) design guidelines for systems to support affective...
متن کاملAdapting Tv Based Applications’ User Interface
In this paper we describe the design and implementation of an adaptive multimodal fission component integrated in the multimodal GUIDE framework. This component is able to adapt any TV based application’s UI to a specific user’s characteristics making possible for elderly and impaired users to interact by offering several output modalities that tries to overcome his difficulties of interaction.
متن کاملEvaluating tangible objects for multimodal interaction design
The design of applications with multimodal interfaces currently implies complex handcrafting by interface experts, lack of compliance with industry standards of cost effectiveness, maintenance and user focus such as those achieved by the current User-Centered Design methods. This paper presents an initial step towards a design by-example approach, whereby the end-user’s multimodal preferences f...

متن کاملA Hybrid Tool For User Interface Modeling And Prototyping
Although many methods have been proposed, model-based development methods have only to some extent been adopted for UI design. In particular, they are not easy to combine with user-centered design methods. In this paper, we present a hybrid UI modelling and GUI prototyping tool, which is designed to fit better with IS development and UI design traditions. The tool includes a diagram editor for ...
