“…Looking at the sensory substitution approaches, the practical usability of the acoustical feedback is often limited for mobility applications. This because it might interfere and reduce user's auditory abilitywhich is usually augmented in blind people, disturbing posture and equilibrium control and severely affecting social interactions [6], [7]. For the reasons above, tactile feedback seems to represent a more natural manner to convey navigational information.…”

Recently, in the attempt to increase blind people autonomy and improve their quality of life, a lot of effort has been devoted to develop technological travel aids. These systems can surrogate spatial information about the environment and deliver it to end-users through sensory substitution (auditory, haptic). However, despite the promising research outcomes, these solutions have met scarce acceptance in real-world. Often, this is also due to the limited involvement of real end users in the conceptual and design phases. In this manuscript, we propose a novel indoor navigation system based on wearable haptic technologies. All the developmental phases were driven by continuous feedback from visually impaired persons. The proposed travel aid system consists of a RGB-D camera, a processing unit to compute visual information for obstacle avoidance, and a wearable device, which can provide normal and tangential force cues for guidance in an unknown indoor environment. Experiments with blindfolded subjects and visually impaired participants show that our system could be an effective support during indoor navigation, and a viable tool for training blind people to the usage of travel aids.

“…Over the last decades, all kinds of electronic assistive devices have been proposed for safe and independent mobility of the visually impaired. The assistive systems scan the environment (using different technologies, such as sonar, 3D camera [2]) and display the information to other senses. The human-machineinterfaces nowadays not only routinely utilize the auditory stimuli modality, but also increase the use of tactile modality.…”

A tactile system to support severe visually-impaired or blind people in the world for their orientation and navigation had been developed. To optimize the design, some parameters of tactile display device were evaluated. In the present paper, we focused on the reaction time to tactile stimuli. In the test, the stimuli were produced through a vibration belt that was worn around the participants' waist. In the choice reaction time task, the participants had to click corresponding arrow keys according to the location of a tactile signal. The findings of this study provided a reference of the reaction time range, so as to design a more effective and safe tactile navigation system.
