The Apr. 28, 2013 news release on EurekAlert provides more detail,

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.

Here’s the video where the researchers demonstrate their morphees,


The work will be presented at ACM CHI 2013, sometime between Saturday 27 April to Thursday 2 May 2013, in Paris, France. For those who’d like to see the paper which will be presented, here’s a link to it,

Morphees: Toward High “Shape Resolution” in Self-Actuated Flexible Mobile Devices by
Anne Roudaut, Abhijit Karnik, Markus Löchtefeld, and Sriram Subramanian

After reading the news release and watching the video, I am reminded of the ‘morph’ concept, a shapeshifting, wearable device proposed by Cambridge University and Nokia. Last I wrote about that project, they had announced a stretchable skin, as per my Nov. 7, 2011 posting.

For those who are interested in what ACM CHI 2013 is all about, from the home page,

The ACM SIGCHI Conference on Human Factors in Computing Systems is the premier international conference on human-computer interaction. CHI 2013 is about changing perspectives: we draw from the constantly changing perspectives of the diverse CHI community and beyond, but we also change perspectives, offering new visions of people interacting with technology. The conference is multidisciplinary, drawing from science, engineering and design, with contributions from research and industry in 15 different venues. CHI brings together students and experts from over 60 countries, representing different cultures and different application areas, whose diverse perspectives influence each other.

CHI 2013 is located in vibrant Paris, France, the most visited city in the world. The conference will be held at the Palais de Congrès de Paris. First in Europe in research and development, with the highest concentration of higher education students in Europe, Paris is a world-class center for business and culture, with over 3800 historical monuments.The Louvre’s pyramid captures the spirit of CHI’13, offering diverse perspectives on design and technology, contrasting the old and new. The simple glass sides reveal inner complexity, sometimes transparent, sometimes reflecting the people and buildings that surround it, in the constantly
changing Paris light.

CHI 2013 welcomes works addressing research on all aspects of human-computer interaction (HCI), as well as case studies of interactive system designs, innovative proof-of-concept, and presentations by experts on the latest challenges and innovations in the field. In addition to a long-standing focus on professionals in design, engineering, management, and user experience; this year’s conference has made special efforts to serve communities in the areas of: design, management, engineering, user experience, arts, sustainability, children, games and health. We look forward to seeing you at CHI 2013 in Paris!

As I recall, ACM stands for Association of Computing Machinery, CHI stands for computer-human interface, and SIG stands for Special Interest Group.

ETA May 13, 2013: I meant to do this two weeks ago (Apr. 30,2013), ah well. Roel Vertegaal and his team at Canada’s Queen’s University introduced something called a MorePhone, which can curl up and change shape, at the CHI 2013. From the Apr. 30, 2013 news release on EurekAlert*,

Researchers at Queen’s University’s Human Media Lab have developed a new smartphone – called MorePhone – which can morph its shape to give users a silent yet visual cue of an incoming phone call, text message or email.

“This is another step in the direction of radically new interaction techniques afforded by smartphones based on thin film, flexible display technologies” says Roel Vertegaal (School of Computing), director of the Human Media Lab at Queen’s University who developed the flexible PaperPhone and PaperTab.

“Users are familiar with hearing their phone ring or feeling it vibrates in silent mode. One of the problems with current silent forms of notification is that users often miss notifications when not holding their phone. With MorePhone, they can leave their smartphone on the table and observe visual shape changes when someone is trying to contact them.”

MorePhone is not a traditional smartphone. It is made of a thin, flexible electrophoretic display manufactured by Plastic Logic – a British company and a world leader in plastic electronics. Sandwiched beneath the display are a number of shape memory alloy wires that contract when the phone notifies the user. This allows the phone to either curl either its entire body, or up to three individual corners. Each corner can be tailored to convey a particular message. For example, users can set the top right corner of the MorePhone to bend when receiving a text message, and the bottom right corner when receiving an email. Corners can also repeatedly bend up and down to convey messages of greater urgency.

I have written about Vertegaal and his team’s ‘paper’ devices previously. The most recent piece is this Jan. 9, 2013 posting, Canada’s Queen’s University strikes again with its ‘paper’ devices. You can find out more about Plastic Logic here.

SpiderSense and wearable computers

Nancy Owano in her Feb. 23, 2013 article for phys.org, Wearable display meets blindfold test for sensing danger, features a project (SpiderSense) from the University of Illinois at Chicago that will be presented at the Augmented Human ’13 conference to be held March 7 – 8, 2013 in Stuttgart, Germany,

The researchers behind SpiderSense define it as a wearable device that projects the wearer’s near environment on the skin. The suit gives the user a special directional awareness of surrounding objects. They have explored a scenario where multiple sites over the body, rather than just hands, are fitted with transducers. These transducers relay information about the wearer’s environment into tactile sensations.

Modules are distributed across the suit to give the wearer as near to 360-degree ultrasound coverage as possible. The system modules can scan the environment; they are controlled through a Controller Box. The box carries the power source, the electronics and the system logic. The modules and the Controller Box are connected by means of ten pin ribbon cables. The researchers said that, in the future, this could be replaced by a wireless Bluetooth connection.

You can find out more about SpiderSense from its presentation webpage on the University of Illinois at Chicago Electronic Visualization Laboratory (EVL) website,

Sensing the environment through SpiderSense

Augmented Human ’13, 4th International Conference in Cooperation with ACM SIGCHI, Stuttgart, Germany

Recent scientific advances allow the use of technology to expand the number of forms of energy that can be perceived by humans. Smart sensors can detect hazards that human sensors are unable to perceive, for example radiation. This fusing of technology to human’s forms of perception enables exciting new ways of perceiving the world around us. In this paper we describe the design of SpiderSense, a wearable device that projects the wearer’s near environment on the skin and allows for directional awareness of objects around him. The millions of sensory receptors that cover the skin presents opportunities for conveying alerts and messages. We discuss the challenges and considerations of designing similar wearable devices.

A Feb. 22, 2013 article by Hal Hodson for New Scientist inspired Owano who acknowledges that to be the case in her end notes,

Mateevitsi [Victor Mateevitsi] tested the suit out on students, getting them to stand outside on campus, blindfolded, and “feel” for approaching attackers. Each wearer had ninja cardboard throwing stars to use whenever they sensed someone approaching them. “Ninety five per cent of the time they were able to sense someone approaching and throw the star at them,” says Mateevitsi.

The SpiderSense presentation is scheduled for March 7, 2013 at the Augmented Human ’13 conference or as it’s also known, the 4th International Conference in Cooperation with ACM SIGCHI (Association for Computing Machinery, Special Interest Group on Computer-Human Interaction). The team, as per Hal Hodson’s article,  hopes to start human trials of SpiderSense with visually impaired individuals.
