“…Cognitive variances, which include distinct preferences in frames of reference and navigation routes, exist in the mental maps of both blind and sighted individuals [22]. Furthermore, effective verbal communication of spatial information between individuals with visual impairments and sighted individuals poses challenges due to the potential ambiguity and lack of clarity in verbal expressions, stemming from disparities in perceptual concepts [23][24][25]. Consequently, there is a demand for accessible CAD tools for the visually impaired, facilitating communication about spatial concepts to establish mutual understanding with sighted individuals through a shared spatial language.…”

Tactile maps are crucial for orientation and mobility (O&M) training for visually impaired people (VIP) to gain spatial knowledge of their surroundings. However, existing tactile maps are limited in their ability to facilitate actively generating information, modifying, and sharing by VIP individuals, making it challenging for them and O&M specialists to create and customize maps independently. To address this issue, we propose Archi-TangiBlock (ATB), an accessible computer-aided design (CAD) tool for VIP. ATB comprises a modular block-based tangible user interface that modularizes architectural landmarks, a panel for plugging in block modules, and a computer interface. Visually impaired users can use ATB to create a 3D CAD model by constructing a space with the blocks, enabling active learning. We evaluated ATB with visually impaired participants, and our results demonstrate that ATB enables visually impaired users to easily build maps, achieving a remarkably low error rate of 1.2%, and to gain an understanding of the overall spatial layout at a rate twice as fast as compared to conventional tactile maps.

: In this paper we propose a walking aid system for blind people by exploiting a haptic feedback equipment. The proposed system is a form of haptic feedback cane which is composed of MCU, communication module, sensing module and actuator. The proposed system recognizes obstacles around the blind by using ultrasonic sensors in the sensing module. Moreover, the system generates feedback information about the detected obstacle and then notifies the information to the blind through the actuator. The blind can notice the direction of the detected obstacle with the haptic feedback equipment and vibration motor. Futhermore, the proposed system controls a nearby IoT(Internet of Things) system by utilizing push buttons through the ZigBee communication. Finally, the blind can easily decide the direction of the obstacle without interference of terrain feature by using the proposed system.
