3D scans of a person's hand provide detailed measurements useful in design and medical treatments. They can also be used to personalise products, like a 3D-printed plastic cast that fits perfectly, is water-resistant and is reusable. However, most 3D scanners have trouble scanning hands.
Curatio is a 3D scanner designed specifically to produce high quality scans of the human hand. The project builds on an earlier proof of concept scanner design and user experience concept. Unlike most other scanners it can handle the hand's difficult shape and texture. That means it can obtain accurate measurements of virtually anyone's hand. Also of people with an impairment. And the intuitive interface means basically anyone can do it.
With its low-cost components, Curatio can commoditise the use of accurate 3D scanning. Enabling improved hand therapy and a new world of design opportunities for personalised products like braces.
Developing a robust 3D scanning system using 53 Raspberry Pi’s
24 major design iterations to achieve accurate scanning without calibration
On-screen UIs to support complex interactions involving two devices and two people
To enable anyone to get accurate results, Curatio's interface was designed to guide both operator and subject through the process. It's a matter of selecting the scanning protocol and following the instructions. The scanner shows the correct hand postures, ensuring reproducible results.
