Creating affordable, usable and wearable smart glasses to improve the lives of millions of people with impaired vision was the goal for Oxsight, a spin-out from Oxford University.

the challenge

Oxsight Prism captures live video of the real world which relays to two HD displays that are then projected in front of the user’s usable area of vision. Via augmented reality, Prism can display visual information in a variety of ways to help the user in various scenarios such as enhancing faces, make writing more legible, or highlight approaching objects and obstacles.

OPD incorporated this technology into a wearable device that would be both stylish and comfortable enough for the user to wear for extended periods.


A key part to the glasses working is the ‘occluder’ – a shroud that surrounds the glasses to prevent additional light from coming through. Anthropomorphic data and multiple prototypes helped ensure that the glasses fit as many face types as possible.

As well as the Prism, the Oxsight Crystal was created for those with less severe visual impairment. Removing the occluder means the glasses provide unrestricted peripheral awareness and the user can activate augmented reality on-demand.

the results

Applying these human factors and ergonomic evaluation meant the design ended up truly adaptable and intuitive, resulting in a positive user experience.
