An interactive data visualization built with p5.js that explores the relationship between assistive technology access, economic development, and quality of life across countries. The project demonstrates how access to assistive technologies—including future technologies such as voiceless speech interfaces—can influence societal, economic, and health outcomes.
Voiceless speech interfaces (also called silent speech interfaces) are emerging assistive technologies that enable communication without producing audible speech. They have the potential to improve accessibility for individuals with speech impairments while also offering privacy benefits for everyday communication.
This visualization combines multiple international datasets to investigate how differences in assistive technology coverage relate to:
- GDP per capita
- Quality of Life Index
- Population requiring Augmentative and Alternative Communication (AAC)
- Government support for assistive technologies
The goal is to highlight global disparities in accessibility and illustrate the broader societal and economic impacts of assistive technology.
- Interactive world data visualization
- Country-by-country comparison
- Multiple datasets combined into a single visualization
- Hover and click interactions
- Visual representation of accessibility disparities
- Built entirely with p5.js
This project combines the following publicly available datasets:
| Dataset | Purpose |
|---|---|
| WHO Assistive Technology Data | Government support and assistive technology coverage |
| GDP per Capita | Economic indicator for each country |
| Quality of Life Index | Overall quality of life measurement |
| World Population Data | Country population statistics |
| NIH AAC Statistics | Estimate of the population requiring augmentative and alternative communication |
These datasets are merged to estimate the number of people affected by access—or lack of access—to assistive technologies around the world.
- p5.js
- JavaScript
- HTML5
- CSS3
Access to assistive technology varies dramatically across countries. By visualizing these differences alongside economic and quality-of-life indicators, this project aims to encourage discussion about accessibility, healthcare equity, and the future potential of emerging technologies such as voiceless speech interfaces.
