Researchers in Rensselaer’s Social Behavioral Research Laboratory (SBRL) are examining the usability of a miniature model of a large-scale science exhibit in the New York Hall of Science. The interactive, tactile model aims to make museum exhibits more accessible for blind and low-vision visitors by allowing them to learn about exhibits through a combination of touching and listening.

The model is a prototype for a complete museum installation of audio/tactile model interfaces for many of the New York Hall of Science’s exhibits and displays.

Developed by Touch Graphics — a company specializing in developing learning tools for the visually impaired — a person can touch any one of its 54 metal parts to hear audio information identifying the part and how it works.

Led by James Watt, professor of communication and director of the SBRL, researchers are observing multiple people as they use the model, and interviewing them about their experiences and their suggestions for improvement. 

The Rensselaer researchers are working with five visually impaired people who are testing the model, and their experiences will be compared to that of five sighted people who will use the model. When testing concludes, SBRL researchers will analyze the data they’ve collected to evaluate the prototype’s usability, and provide Touch Graphics with suggestions to improve the system.

Development of the model was funded by National Science Foundation Small Business Innovation Research funding. Rensselaer is the designated research partner on the grant.
