This paper presents a novel framework for partial matching and retrieval of 3-D models based on a query-by-range-image approach. Initially, salient features are extracted for both the query range image and the 3-D target model. The concept behind the proposed algorithm is that, for a 3-D object and a corresponding query range image, there should be a(More)
Existing information on the Web and especially maps are graphically-orientated and in most cases visually impaired users have very restricted access and find it difficult to recognize this kind of visual representation. For visually impaired people and especially for blind users alternative information presentation ways must be found, which would replace(More)
Among the key components of designing accessible products and services for disabled users is accessibility testing and support. The VERITAS FP7 project has developed a platform that consists of several tools that provide automatic simulation feedback and reporting for built-in accessibility support at all stages of ICT product development. In this(More)
This paper presents a framework for automatic simulated accessibility and ergonomy testing of virtual prototypes of products using virtual user models. The proposed virtual user modeling framework describes virtual humans focusing on the elderly and people with disabilities. Geometric, kinematic, physical, behavioral and cognitive aspects of the user(More)
The present paper introduces a set of ergonomic factors which are evaluated by a framework that performs automatic, simulated ergonomic analysis of virtual environments. The proposed framework uses virtual user models describing users with or without physical deficiencies and evaluates the ergonomy of virtual environments for the specific users. Two novel(More)
In this paper, we present a novel methodology to evaluate the accessibility of products using virtual prototypes. The novelty is that the product evaluation is based on simulating the interactions of users with physical deficiencies in virtual and immersive environments. Virtual users with special needs, e.g. elderly or impaired people, were modelled using(More)
Elderly and impaired persons constitute an important part of our societies. Existing practices to test accessibility features on forthcoming consumer products and services rely on tests with real impaired users on the industrial prototypes. Our approach comes to automate the evaluation process and introduce it in early phases of the product design. The(More)
