Making digital home assistants more accessible

Project Description

Digital home assistants are exlusively designed to be interacted with via a speech interface. This conceptual device allows digital home assistants to be completely operational without voice whilst maintaining the same level of convenience and experience of a speech interface.

By giving the user the ability to issue non-verbal commands from anywhere in a given room (or home, if the device is installed in each room) without having to carry a physcial control input device, the experience of a speech interface can be holistically replicated.

Sign language and/or hand signs offer a method for conveying complex non-verbal commands. Commands which will be interpreted by an integrated 360 degree camera, providing the device with a birds eye view of the entire room. This concept is implemented as part of a light fixture, requiring it to be mounted onto the ceiling. Acknowledgement of commands are conveyed to the user by changing the hue of the light.
