“…For the display of UI, a tactile windowing system was designed, taking into consideration the requirements for twodimensional tactile representations [16]. The windowing system divides the display into braille regions for different sorts of information [14,16]. These regions are, amongst others, the header region for holding window title information or a menu path, the body region displaying the content of the application and detail region for screen reader output or information about the focused element (see Fig.…”

The use of virtual classrooms by blind users is hindered e.g. by inaccessible user interfaces, graphical and dynamical content, as well as synchronous communication. Based on a requirements catalogue for accessible virtual classrooms and existing concepts to eliminate barriers for blind learners, alternative concepts are presented for a two-dimensional Braille display. An evaluation using tactile paper prototyping indicates an improvement towards accessibility and equal usage for all participants.

“…However, the system requires a multiple stimulator pads attached to the user's fingers for generating force feedback, and is limited to the speed of the stimulation pads. Others techniques such as matrix interface [11], [12] are based on the generation of a 3 D surface, allowing the use of one or more fingers, which may vary in both space and time. So the resolution is related to the number of used actuators.…”

International audience— This paper presents a method to control ultrasonic waves on a beam, allowing to obtain a Multi-touch ultrasonic tactile stimulation in two points, to give the sensation to two fingers, from two piezoelectric transducers. The multi-modal approach and the vector control method are used to regulate the vibration amplitude, in order to modulate the friction coefficient with the fingers. An analytical modelling is presented, with experimental validation. Finally a psychophysical experiment shows that a multi-touch ultrasonic tactile stimulation is possible

“…Nowadays the trend in this field is gearing toward dynamic graphical tactile displays: the purpose could be either to provide a kind of tactile graphical user interface (Schiewe et al, 2009 ) (since actually almost all the ICT systems used in daily life have a graphical user interface) or to go beyond standard text by introducing tactile icons (Pietrzak et al, 2009 ). For these reasons new tactile interfaces have to be devised, able to overcome the main limitation of commonly available braille bars strictly focused on representing text encoded in standard braille.…”

Different tactile interfaces have been proposed to represent either text (braille) or, in a few cases, tactile large-area screens as replacements for visual displays. None of the implementations so far can be customized to match users' preferences, perceptual differences and skills. Optimal choices in these respects are still debated; we approach a solution by designing a flexible device allowing the user to choose key parameters of tactile transduction. We present here a new dynamic tactile display, a 8 × 8 matrix of plastic pins based on well-established and reliable piezoelectric technology to offer high resolution (pin gap 0.7mm) as well as tunable strength of the pins displacement, and refresh rate up to 50s−1. It can reproduce arbitrary patterns, allowing it to serve the dual purpose of providing, depending on contingent user needs, tactile rendering of non-character information, and reconfigurable braille rendering. Given the relevance of the latter functionality for the expected average user, we considered testing braille encoding by volunteers a benchmark of primary importance. Tests were performed to assess the acceptance and usability with minimal training, and to check whether the offered flexibility was indeed perceived by the subject as an added value compared to conventional braille devices. Different mappings between braille dots and actual tactile pins were implemented to match user needs. Performances of eight experienced braille readers were defined as the fraction of correct identifications of rendered content. Different information contents were tested (median performance on random strings, words, sentences identification was about 75%, 85%, 98%, respectively, with a significant increase, p < 0.01), obtaining statistically significant improvements in performance during the tests (p < 0.05). Experimental results, together with qualitative ratings provided by the subjects, show a good acceptance and the effectiveness of the proposed solution.
