Dots is an inclusive interface for future spatial computing, which empowers the disabled people to design their way to interact with MR and IoT based on their body conditions.
Disabilities are often highly individual, which leads to a lack of generality in inclusive design. For better adoption, a large number of inclusive design projects are aiming at smaller groups of people, which makes a high amount of different systems had to be designed for users with diverse conditions.
Dots, instead of making different users adapt to one system, is a flexible and customizable interface that adapts to different users.
To explore the possibility of an inclusive natural user interface for people who have physical disabilities, several experiments were conducted.
The goal of these experiments is to extract a full body movement-based interaction pattern for the spatial interaction.
We gave participants four 3D object manipulation tasks and set different limitations of using their bodies.
From the observed behaviour in the experiment, we found that all the interactions could be described as the relative motion of two points in 3D space!
Depending on users body conditions, they can attach two dots to any of their body parts, as long as these two parts can accomplish at least one interaction patterns. It is also possible to utilise the environment like attaching one dot on the table. And the exact attaching points depend on the specific task that users wish to do.
