Haptic 3D Surface Representation of Table-Based Data for People With Visual Impairments
This paper introduces "relief charts"—3D surface representations of standard data visualizations (bar graphs, pie charts, scatter plots, radar charts) designed to make complex tabular data accessible to people with visual impairments. The approach is…

Principles for Designing Large-Format Refreshable Haptic Graphics Using Touchscreen Devices: An Evaluation of Nonvisual Panning Methods
This paper addresses a fundamental challenge in touchscreen-based accessibility: how to provide non-visual access to large-format graphical materials like maps that exceed the device's screen size. While touchscreens represent the fastest-growing com…

Consistency of a Tactile Pattern Set
This paper addresses a fundamental challenge in tactile graphics production: how to create fill patterns that remain recognizable and distinguishable across different production media with varying resolutions. The three media studied were microcapsul…

How Can Haptic Feedback Assist People with Blind and Low Vision (BLV): A Systematic Literature Review
This comprehensive systematic literature review examines 20 years (2004–2024) of research on haptic assistive tools for people who are blind or have low vision (BLV), analyzing 132 papers from 11 major HCI venues including CHI, ASSETS, UIST, and IEEE…

Autonomous Selection and Printing of 3D Models for People Who Are Blind
This paper addresses a significant autonomy gap: while 3D printed models are increasingly used in schools for blind students to understand spatial concepts through touch, the process of finding and printing these models has required sighted assistanc…
