“…As important as it is to help ''see'' and discriminate properly and comfortably stimulation, the calibration step is not an easy problem. Gradual adjustment by static stimulation, region by region, so that perception is uniform over the entire surface of the tongue, has been used so far (Vuillerme et al 2007(Vuillerme et al , 2008aVuillerme and Cuisinier 2008;Chenu et al 2009;Robineau et al 2007;Robineau 2009;Chenu 2009). However, we found that this protocol is not very effective for visual substitution.…”

“…In practice, camera pictures or movies encoded in gray levels are displayed via an electro-stimulation device on the surface of a body part such as the skin or the tongue. Medico-technical devices are developed based on this principle using a TDU (the tongue display unit is composed of a control box and a square matrix of about 10 9 10 electrodes or taxels for tactile pixels) to take care of sensory-motor disabilities like blindness or macula degeneracy due to aging (Bach-y-Rita et al 1969, 1998Sampaio et al 2001;Kupers and Ptito 2004;Ptito et al 2005;Danilov and Tyler 2005;Kercel 2005;Arnoldussen et al 2008), to allow equilibrium rehabilitation (Vuillerme et al 2007(Vuillerme et al , 2008aVuillerme and Cuisinier 2008), to prevent the formation of pressure sores (Vuillerme et al 2007;Chenu et al 2009;Chenu 2009), or even to guide specific actions like in surgery or other acts of trajectory tracking or of target localization requiring a guiding assistance (Robineau et al 2007;Robineau 2009;Bluteau 2010).…”

Influence of Sparkle and Saccades on Tongue Electro-Stimulation-Based Vision Substitution of 2D Vectors

Vision substitution by electro-stimulation has been studied since the 60s beginning with P. Bach-y-Rita. Camera pictures or movies encoded in gray levels are displayed using an electro-stimulation display device on the surface of a body part, such as the skin or the tongue. Medical-technical devices have been developed on this principle to compensate for sensory-motor disabilities such as blindness or loss of balance, or to guide specific actions, such as surgery. However, the electrical signals of stationary or moving slowly moving objects, displayed on a Tongue display unit (TDU), are quickly lost due to saturation of receptors undergoing electrostimulation. We propose to add random saccades or sparkle to the displayed visual scene to increase the quality of pattern recognition by the subjects. In the present experimental trimodal study (normal vision, TDU vision substitution, or both), we show that the presence of a moderate sparkle level enhances the perception of the direction of lines drawn on a TDU and reduces the response time.

“…The work of Bach-y-Rita on sensory substitution for the blind [2] as well as the more recent scientific works on the Tongue Display Unit (TDU) for pressure ulcer prevention [3], balance problems [4] and the guiding of surgical gesture [5] have inspired the conception of an innovative device enabling to rehabilitate or to palliate these sensory deficits. Following this approach, this paper describes an innovative home-based hand rehabilitation systemdevice that exploits sensory substitution of median sensory deficits in the traumatized hand.…”

International audiencePost-traumatic median nerve sensitive deficits are frequent. They are a source of permanent handicap that dramatically decreases the level of autonomy and the quality of life of persons suffering from these deficits. Surgical repair is possible, but the results are not always functionally useful. Therefore, prosthetic approaches do represent an alternative solution that needs to be explored. Along these lines, this paper describes an innovative home-based hand rehabilitation system device that exploits sensory substitution of median sensory deficits in the traumatized hand. It is composed of a glove bearing smart textile pressure sensors and a wristband providing vibratory biofeedback to the user. The goal of this sensory-substitution system is to provide for patients an effective method to compensate the lack of sensitivity of the finger pads and to recover a functional hand use. This innovative system is intended to be employed for assessment, training and rehabilitation exercises at home

Abstract-Most conventional computer-aided navigation systems assist the surgeon visually by tracking the position of an ancillary and by superposing this position into the 3D preoperative imaging exam. This paper aims at adding to such navigation systems a device that will guide the surgeon towards the target, following a complex preplanned ancillary trajectory. We propose to use tactile stimuli for such guidance, with the design of a vibrating belt. An experiment using a virtual surgery simulator in the case of skull base surgery is conducted with 9 naïve subjects, assessing the vibrotactile guidance effectiveness for complex trajectories. Comparisons between a visual guidance and a visual+tactile guidance are encouraging, supporting the relevance of such tactile guidance paradigm.
