The aim of this study was to assess the stability of the Gross Motor Function Classification System (GMFCS) by examining whether children with cerebral palsy (CP) remain in the same level over time. Participants were 610 children with CP (342 males, 268 females; mean age 6y 9mo [SD 2y 10mo]), range 16mo-13y). Children were assessed 2 to 7 times (mean 4.3)(More)
This paper addresses knowledge-based authentication systems in self-service technology, presenting the design and evaluation of the Visual Identification Protocol (VIP). The basic idea behind it is to use pictures instead of numbers as a means for user authentication. Three different authentication systems based on images and visual memory were designed and(More)
Emotions, and emotional expression, have a broad influence on the interactions we have with others and are thus a key factor to consider in developing social robots.

Robots are gradually but steadily being introduced in our daily lives. A paramount application is that of education, where robots can assume the role of a tutor, a peer or simply a tool to help learners in a specific knowledge domain. Such endeavor posits specific challenges: affective social behavior, proper modelling of the learner's progress,(More)
Machinima is the appropriation of software-generated 3D virtual environments, typically video games, for filmmaking and dramatic productions. The creation and distribution technology of machinima tends to hide the nature of the performer, provoking consideration of a definition of 'liveness' that can accommodate the real-time rendering of screen content by(More)
The HapticWave is a haptic audio waveform display device that has been developed in collaboration with a group of audio engineers and producers with visual impairments for use in real world recording studio environments. This was not a project led by a designer or driven by a design brief: rather, the genesis of the HapticWave emerged from exchange and(More)
