Prototype mobile devices that can change shape on-demand will be unveiled and could lay down the foundation for creating high shape resolution devices of the future.
The research paper, to be presented at one of the world's most important conferences on human-computer interfaces, will introduce the term 'shape resolution' and its ten features, to describe the resolution of an interactive device: in addition to display and touch resolution.
The research, led by Dr Anne Roudaut and Professor Sriram Subramanian, from the University of Bristol's Department of Computer Science, have used 'shape resolution' to compare the resolution of six prototypes the team have built using the latest technologies in shape changing material, such as shape memory alloy and electro active polymer.
One example of a device is the team's concept of Morphees, self-actuated flexible mobile devices that can change shape on-demand to better fit the many services they are likely to support.
The team believe Morphees will be the next generation of mobile devices, where users can download applications that embed a dedicated form factor, for instance the "stress ball app" that collapses the device in on itself or the "game app" that makes it adopt a console-like shape.
Dr Anne Roudaut, Research Assistant in the Department of Computer Science's Bristol Interaction and Graphics group, said: "The interesting thing about our work is that we are a step towards enabling our mobile devices to change shape on-demand.
Imagine downloading a game application on the app-store and that the mobile phone would shape-shift into a console-like shape in order to help the device to be grasped properly. The device could also transform into a sphere to serve as a stress ball, or bend itself to hide the screen when a password is being typed so passers-by can't see private information."
By comparing the shape resolution of their prototypes, the researchers have created insights to help designers towards creating high shape resolution Morphees.
In the future the team hope to build higher shape resolution Morphees by investigating the flexibility of materials. They are also interested in exploring other kinds of deformations that the prototypes did not explore, such as porosity and stretchability.
