 | U-Note is a system that allows to capture and access the context of a classroom. In class the pupil takes his notes on a notebook. The teacher gives oral explanations, writes on the blackboard, and displays digital documents. The system captures the pupils' notes using an ANOTO digital pen. The explanations, the writings on the blackboard and the actions on the digital documents are captured by the teacher's application. In addition to his notebook, the pupil is given two applications to study his lessons: a mobile application to consult the teacher's documents, and a computer application that completes the notebook for homeworks. This application creates high granularity links between physical and digital documents in order to link pieces of information they contain.

 | Translating graphic objects into tactile objects by mapping dark pixels into raised pins and light pixels into lowered pins is not efficient. The technique we designed allows to explore geometric shapes by guiding the user along the shape with directional Tactons. Thanks to direction and distance information, the user manages to explore an recognize the shape.

 | Designing applications intended for visually impaired children is a difficult task. Their impairment restricts display possibilities, so deseigners have to use other modalities like auditory or haptic modalities. The heterogeneity of haptic devices complicates interactions that use multiple devices. the goal of this architecture is to provide components that allows to combine easily heterogeneous devices, and so ease the development of applications. The architecture also allows to include directly interaction techniques that use these devices.

 | Representating schematics for visually impaired people is a difficult problem. Schematics essentially rely on visual properties, and the direct translation of a visual schematic into an haptic representation is not understandable. This work focused of electric circuits schematics, which the main pieces of information are the electric components and the circuit's topology. They have been represented both with PICOB and Tactons, using icons and guidance systems.

 | There is a great diversity of Tactile sensations. Among them, pressure can be stimulated with pins that translate perpendicularly to the surface of the skin. Several devices are based on pin arrays, and they generally allow to represent letters using the Braille alphabet. Our Tactons are patterns or animations made with raised or lowered pins. The parameters of the signal we identified allow to structure the information displayed on this kind of device.

 | Force feedback devices as the PHANToM have many applications. They allow to explore virtual objects thanks to the sense of touch. Haptic feedback can not only be used to increase realism, but also give information when vision is not available. The PICOB project consisted in finding new force feedback interaction techniques allowing to represent structured information. To realize this we use bumps made by a macroscopic deformation of the surface being explored.
