Haptic technology aims at the artificial creation of the sensation of touching objects. By way of analogy, computer graphics aims at artificially creating the sensation of seeing objects. For example in the medical field, there are numerous instances where haptic technologies can contribute greatly. It can be used to teach and train, or to perform medicine remotely, and be applied to rehabilitation and therapy.  In manufacturing, haptic technologies are now applied to enable the assessment of products before physical mockups are made. One application which we will be pursuing is develop technology that will enable the blind and visually impaired access graphical information.The research to be carried out is aimed at the development of techniques that make it possible to build systems that can create haptic simulations having a great deal of realism. We will aim at expanding the techniques of haptic synthesis to create haptic signals that result from the dynamics of solid interaction (viscosity, plasticity, creep) since, to date, our techniques apply to quasi-static cases only. Another aim of the research will be the development of techniques that can provide cutaneous sensations which are similar to those arising when scanning surfaces, a specific example being reading Braille characters.In parallel, we will seek progress toward the development of a computational theory of haptic perception. We will consider the information that is available to recover the properties of the touched object and deduce the problems that must be solved by the brain to recover the relevant information. It will then be possible to pose the corresponding computational problems. From this,  predictions will be made and behavioral experiments will be designed to test them by systematic manipulation of the cues that participate in the solution of the original problem.

触觉技术旨在人工创造触摸物体的感觉。打个比方，计算机图形学的目的是人为地创造看到物体的感觉。例如，在医疗领域，触觉技术可以发挥巨大作用的例子有很多。它可以用于教学和培训，或远程进行医疗，并应用于康复和治疗。  在制造业中，触觉技术现在被应用于在制作物理模型之前对产品进行评估。我们将追求的一个应用是开发一种技术，使盲人和视障人士能够访问图形信息。要进行的研究旨在开发技术，使构建能够创建高度真实的触觉模拟的系统成为可能。我们的目标是扩展触觉合成技术，以创建由固体相互作用动力学（粘度、塑性、蠕变）产生的触觉信号，因为迄今为止，我们的技术仅适用于准静态情况。该研究的另一个目标是开发能够提供类似于扫描表面时产生的皮肤感觉的技术，一个具体的例子是阅读盲文字符。同时，我们将寻求触觉感知计算理论发展的进展。我们将考虑可用于恢复触摸物体的属性的信息，并推断出大脑必须解决的问题以恢复相关信息。然后就可以提出相应的计算问题。由此，将做出预测，并设计行为实验，通过系统地操纵参与解决原始问题的线索来测试预测。
