Metamodels Infrastructure and Heuristics for Metamodel-Driven Multi-touch Interaction

Part 5: Gesture and Tactile User InterfacesInternational audienceNovice users usually find it hard to manipulate models by using traditional Model-Driven Development techniques, because of the gap between the modeling tools and these users’ mental models. In this context, multi-touch interfaces emerge as an alternative to make it easier for novice users to interact with the models by using natural gestures and taking advantage from the popularity that touch-based devices have achieved. In this paper, a metamodel infrastructure and a set of heuristics are presented to automatically generate multi-touch visual editors for manipulating models. The editor generated is driven by a metamodel that also prevents the user from creating not valid models. These heuristics have been validated while developing an environment for novice users, such as psychologists or physiotherapists, for the treatment of people with Acquired Brain Injury

Validity of the comprehensive assessment of prospective memory (CAPM) for use with adults with traumatic brain injury

Objective: To expand upon the existing psychometric properties of the Comprehensive Assessment of Prospective Memory (CAPM) for use with adults with traumatic brain injury by examining concurrent and criterion validity. Method: Participants were 45 adults with a traumatic brain injury. Participants and their relatives completed Section A of the CAPM and a measure of psychosocial integration. Participants were also administered two neuropsychological tests of prospective memory, the Cambridge Prospective Memory Test (CAM-PROMPT) and the Memory Intentions Screening Test (MIST). Concurrent validity was measured by comparing scores on the CAPM with scores on the CAM-PROMPT and MIST. Criterion validity was examined by correlating CAPM scores with level of psychosocial integration. Results: Participant self-reports on the CAPM were not significantly correlated with the CAM-PROMPT or MIST, but were significantly correlated with level of psychosocial integration. Relative reports on the CAPM were correlated significantly with total score on the MIST and CAM-PROMPT and level of psychological integration. Conclusions: The findings indicate that the concurrent validity of the self-report version of CAPM is low suggesting that selfreports alone do not provide an objective measure for assessing prospective memory function. The relative report version however, demonstrated reasonable concurrent and criterion validity, suggesting that the relative report version of the Section A of the CAPM is a useful means of evaluating frequency of prospective memory failure in adults with traumatic brain injury

An experimental study of dynamic dominators

Motivated by recent applications of dominator computations we consider the problem of dynamically maintaining the dominators of a flowgraph through a sequence of insertions and deletions of edges. We present new algorithms and efficient implementations of existing algorithms and exhibit their efficiency in practice

Unawareness and/or denial of disability: Implications for occupational therapy intervention

Occupational therapy focus on client-centred, occupational performance intervention may become complicated by the phenomena of self-awareness. The problem of awareness deficits in clients with neurological disorders may be attributed to neurological impairment of self-awareness and/or psychological denial of disability. These phenomena present themselves more commonly in combination than dichotomously and have implications for treatment outcomes. Individuals with impaired self-awareness or denial face difficulties with motivation and participation in therapy, and the adoption of compensatory strategies, which ultimately impacts on rehabilitation outcome. The extent of unawareness versus denial can be assessed by observation of a client's behavior and this information can be very useful in directing the treatment approach. The purpose of this paper is, therefore, to discuss the phenomenon of unawareness and/or denial of disability and its importance to successful rehabilitation outcomes, current thinking and research conducted in different countries. Also, detailed case examples of three clients representing three major populations of traumatic brain injury, stroke and schizophrenia who may exhibit unawareness and/or denial of disability will be presented, including intervention strategies for both phenomena
