New Technology Enables Many-Fold Reduction in the Cost of Refreshable Braille Displays
This paper from the National Institute of Standards and Technology (NIST) describes a novel rotating-wheel design for refreshable Braille displays that could reduce costs by up to a factor of ten compared to existing displays. The dominant cost facto…

Haptic Virtual Reality for Blind Computer Users
This paper presents three experiments investigating how blind and sighted people perceive virtual textures and 3D objects through the Impulse Engine 3000, a force-feedback haptic device with a probe that users manipulate in three degrees of freedom. …

Combining Haptic and Braille Technologies: Design Issues and Pilot Study
This paper presents the Pantobraille, a novel device that combines a single braille cell with a pantograph-based force feedback device to allow blind users to navigate and read content on graphical user interfaces. Developed as part of the CITI PC-Ac…

Tactile Accessibility: Does Anyone Need a Haptic Glove?
This paper presents FeelX, a low-cost haptic glove system designed to enable blind users to tactilely explore graphical user interfaces (GUIs) by moving their hands on any flat surface such as a desk or table. The fundamental problem addressed is tha…

Participatory Design Using Sensory Substitution Devices with Tactile and Audio Feedback
This student research paper describes a participatory design study with a single blind participant (TC, blind from birth) to develop a sensory substitution device that provides a physical experience of spatial awareness through tactile or auditory fe…

Evaluating Wrist-Based Haptic Feedback for Non-Visual Target Finding and Path Tracing on a 2D Surface
This paper investigates wrist-worn haptic wristbands as a means to provide directional hand guidance for blind and visually impaired users on a 2D surface. Precisely guiding a blind person's hand has applications ranging from tracing printed text to …

A Demo of Talkit++: Interacting with 3D Printed Models Using an iOS Device
This Cornell Tech demo presents Talkit++, an iOS application that adds interactive multimedia labels to 3D printed tactile models for visually impaired students. Teachers of the visually impaired (TVIs) increasingly use 3D printers to create tactile …

Enabling Collaboration in Learning Computer Programing Inclusive of Children with Vision Impairments
This paper from Microsoft Research explores how Torino, a physical programming language, enables collaborative learning of computer programming by children aged 7-12 with mixed visual abilities — from full blindness to full sight. Torino uses tangibl…

Developing a Wearable Tactile Prototype to Support Situational Awareness
This doctoral consortium paper from UMBC describes dissertation research into head-mounted tactile displays for spatial and situational awareness, with applications for people who are blind and those experiencing situational impairments. The research…

"I can't name it, but I can perceive it" Conceptual and Operational Design of "Tactile Accuracy" Assisting Tactile Image Cognition
This paper introduces "tactile accuracy," a new evaluation criterion for measuring how well blind people recognize objects in raised-line tactile images, replacing the conventional "naming accuracy" borrowed from visual image recognition research. Th…
