Making 3D Design Accessible: Haptic Feedback for Sight-Impaired Users
A 2022 Open University study led by Dr. Lisa Bowers explores how Haply’s Inverse3 enables blind and low-vision users to create in 3D using touch.
Dr. Lisa Bowers and the Open University are at the forefront of accessible education. In a 2022 study featured during British Science Week, it showcased MakeActive-UK, a VR touch studio for sight-impaired users, featuring Haply’s Inverse3, a highly portable, force-feedback haptic controller.
The underlying haptics software that was used in the study was the TOIA platform in Unreal Engine, known for its high-fidelity soft body physics capabilities.
For sight-impaired users, traditional computer-aided design (CAD) software like AutoCAD and SolidWorks present significant accessibility challenges. The Inverse3 bridges this gap by enabling users to interact with digital 3D modelling software through touch, allowing them to manipulate shapes and textures with precision.

Direct Quotes from Sight-Impaired Participants
"I was expecting a feedback device arm, but this felt much more responsive with a larger working area than other haptic devices I’ve tried."
"The feedback was very positive - it moved smoothly without resistance, unlike other devices that feel like a fight."
"Feeling an unreal object react to my touch was startling. It's a visceral, powerful experience."
This study is a powerful reminder that innovation doesn’t just mean new - it means more inclusive. As haptic technology continues to evolve, it has the potential to open new doors for those who’ve long been shut out of creative digital spaces. At Haply Robotics, we’re proud to be part of that movement.
