ABSTRACT
Tactile or haptic presentations of computer graphics visualizations can offer more inclusive experiences for persons who are blind or have low vision. However, teaching accessibility with haptics is challenging due to a lack of ready-to-use instructional resources. This Engaging Education Technique and Assignment (EETA) introduces accessibility with haptics and Turtle Graphics after only a few weeks into CS1. The sample assignments feature open-ended exploration to meaningfully map graphical attributes to haptic feedback that could benefit blind or low vision users. Supplementary materials include lesson guides and Python samples.

Toward accessible 3D virtual environments for the blind and visually impaired
DIMEA '08: Proceedings of the 3rd international conference on Digital Interactive Media in Entertainment and Arts3D virtual environments are increasingly used for education, business and recreation but are often inaccessible to users who are visually impaired, effectively creating a digital divide. Interviews with 8 visually impaired expert users were conducted to ...
Chart Reader: Accessible Visualization Experiences Designed with Screen Reader Users
CHI '23: Proceedings of the 2023 CHI Conference on Human Factors in Computing SystemsEven though screen readers are a core accessibility tool for blind and low vision individuals (BLVIs), most visualizations are incompatible with screen readers. To improve accessible visualization experiences, we partnered with 10 BLV screen reader users ...
Universal life: the use of virtual worlds among people with disabilities
With their emphasis on 3D graphics and complex interface controls, it would appear that virtual worlds have little to offer to people with disabilities. On the contrary, multi-user virtual environments, such as Linden Lab's Second Life platform, serve ...
