Researchers at the Ulsan National Institute of Science and Technology (UNIST) in South Korea have developed a table clock that receives information from other devices to alert users of their schedule. The concrete-and-wood "Cuito" clock links itself to other smartphones or computers to acquire information via Wi-Fi at the push of a button. When the concrete element is pressed, the clock hands start moving and a light is illuminated to indicate the user's next scheduled activity. Cuito also has a feature to keep users up to date with their plans, sometimes announcing how much time is left between the current plan and the next one. The UNIST team predicts Cuito will help users "spend the day more effectively while allowing people to understand the concept of time and plan their schedule better." The project won a thesis award at last month's ACM SIGCHI Conference on Human Factors in Computing Systems (CHI 2017) in Denver, CO.

An all-female student team at the Massachusetts Institute of Technology (MIT) is developing a real-time text-to-braille converter that enables people with vision impairments to transcribe an image of printed text into braille on a refreshable display. "If someone opens up a page in a textbook and they would like to understand what that page is saying, they would place our device on the page and hit a button, and the device would capture that printed text through text recognition and convert that into the corresponding braille letters," says MIT's Jessica Shi. A initial proof-of-concept prototype of the device in February 2016 encouraged further development, which thus far has yielded six follow-up prototypes. The team is exploring alternatives to piezoelectric technology used by most refreshable displays, including microfluidics and refined electromagnetic actuation. The team envisions a smartphone-sized, portable device whose braille cells are much less expensive than cells currently on the market.

Efforts are underway to make virtual assistants multilingual and their conversational mode more human-like by applying machine learning and real-time big data analytics. For example, Microsoft researchers in India have begun Project Melange, studying code-mixing by bilingual Indians online to determine how virtual assistants might be trained to respond to a user switching between different languages in a conversation. "To have a digital assistant, something like Cortana, you have to be able to understand [the user base]," says Microsoft's Kalika Bali. Picking up multiple languages in a single dialogue is beyond current systems' abilities, and Microsoft's Sundar Srinivasan says Cortana "needs to really understand human beings, and the bar for that is very high because that means we have to train the assistant with lots of human speech data." Bali says the project team studies every facet of code-mixing, and the biggest challenge it currently faces is obtaining access to sufficient datasets.

Electronic Tattoos: Using Distinctive Body Locations to Control Mobile Devices Intuitively Electronic Tattoos: Using Distinctive Body Locations to Control Mobile Devices Intuitively
Saarland University
May 17, 2017


Researchers at Google and Saarland University in Germany have developed temporary electronic skin tattoos for intuitive control of mobile devices. The researchers spent time experimenting to find the ideal mix of conductive inks and printing processes so they could print the conductive traces and the electrodes as compactly and thinly as possible on tattoo paper. The conductive plastic EDOT:PSS enabled the team to print the tattoo thinner than a hair's breadth, thus ensuring it would fit onto knuckles and wrinkles, while also having the flexibility to withstand compression and stretching. The water-applied "SkinMarks" can be printed in 30 to 60 minutes under laboratory conditions. In addition, each SkinMark is linked to a nearby minicomputer via conductive copper tape. "We are convinced that in the future, everyone will be able to make their own e-tattoo in less than a minute on a standard, commercially available printer," says Saarland professor Jurgen Steimle.

Google officials used the company's annual developer conference to highlight technologies designed to outmode the keyboard and enable more natural and emotive interaction. One example is Google Lens, a computer-vision system that transforms smartphone cameras into input devices. With Lens, users can point the camera at objects and locations and summon relevant information, and in some cases perform commands, such as booking reservations at restaurants the camera faces or logging into online networks by scanning a router's SKU and password. Image-based search also is a capability of Amazon's 2014 Fire Phone, while the beta version of Google Lens was launched earlier this year by Pinterest. "We're getting to the point where using your camera to discover new ideas is as fast and easy as typing," says Pinterest's Albert Pereta. Experts note the method relies on the accuracy of the image-recognition system, and Google is working to refine the technology.

Researchers at the Massachusetts Institute of Technology's (MIT) Tangible Media Group have engineered flat sheets of gelatin and starch that configure themselves into three-dimensional (3D) structures when immersed in water. "This project is the one of the latest to materialize our vision of 'radical atoms'--combining human interactions with dynamic physical materials, which are transformable, conformable, and informable," says MIT professor Hiroshi Ishii. The researchers generated a flat, dual-layer gelatin film with a denser top layer that can absorb more water and curl over the bottom layer, forming a slowly rising arch. The team 3D-printed strips of edible cellulose over the top gelatin layer, which function as a water barrier. Printing cellulose in various patterns onto gelatin enabled predictable control over the structure's reaction to water and the shapes it takes. The research was presented last month at the ACM SIGCHI Conference on Human Factors in Computing Systems (CHI 2017) in Denver, CO.

Researchers at the University of Waterloo in Canada have integrated motion sensors and software so people recovering from hip and knee replacements can see the real-time performance of their rehabilitative physiotherapy exercises. Sensors affixed to limbs transmit data to a computer as patients go through their exercises, and the software applies human body modeling and machine learning to analyze the data and instantly synthesize a stick-figure visual representation of the motion on a screen. The stick figure is displayed side by side with the ideal exercise movement to give patients a basis for comparison. The researchers note the Automated Rehabilitation System's initial outcomes demonstrate that immediate visual feedback improves patient performance. "The system we have developed is quite flexible," says Waterloo professor Dana Kulic. "It can be used for any type of human movement."

Family TV Viewing and SMS Texting Could Help Cut Internet Energy Use Family TV Viewing and SMS Texting Could Help Cut Internet Energy Use
Lancaster University
May 18, 2017


Researchers at Lancaster University and the University of Cambridge in the U.K. recently performed a detailed study on Android device users, comparing their observations with a dataset of nearly 400 mobile devices in the U.K. and Ireland. The team identified four categories of data-hungry service--watching video, social networking, communications, and listening. The researchers note the four categories cumulatively comprise approximately 50 percent of mobile data demand. The team recommends developers create features for devices and apps that encourage users to communally enjoy streamed media, cutting the overall number of data streams and downloads. They also note other ways to conserve energy include reducing previews or encouraging click-throughs to content. In addition, the study found energy expenditure via instant messaging apps' data demand exceeds that of short messaging services by about a factor of 10.

Scientists are using computer-animation methods popular in the movie industry to generate lifelike digital avatars to help hearing and hearing-impaired persons seamlessly communicate via sign language. The Rochester Institute of Technology's Matthew Huenerfauth leads a team using motion-capture technology in which humans use sensor-dotted apparel as they move, with their movement data rendered into open source mathematical models so other researchers can use them to develop avatars. Meanwhile, researchers working on DePaul University's Paula avatar are programming it to mimic the action of "role shifting" by developing mathematical models of how bodies naturally make specific motions, and using them to automate critical parts of Paula's signing through keyframe animation. Georgia Institute of Technology researcher Harley Hamilton's team is developing "CopyCat," a game for improving children's signing skills by having participants interact with a sign-language cat avatar. The cat's responses indicate whether or not players are making the right signing movements, via a motion-sensing camera.

Researchers at Purdue University's C Design Lab are investigating arm and muscle fatigue associated with advancements in the use of hand gestures for mid-air computer interaction. "Arm fatigue--the so-called 'gorilla arm syndrome'--is known to negatively impact user experience and hamper prolonged use of mid-air interfaces," says Purdue professor Karthik Ramani. Ramani led an investigation focusing on determining an individual's arm strength and calculating cumulative subjective fatigue levels. "With a simple depth camera and a dumbbell, we are able to do as good measurements as the other methods," Ramani says. The study estimated the cumulative subjective fatigue at an improved 15-percent error rate over conventional methods. The researchers believe their work will help expedite and encourage the development of improved user interface solutions for virtual and augmented reality systems. The study's results were presented last month at the ACM SIGCHI Conference on Human Factors in Computing Systems (CHI 2017) in Denver, CO.

Researchers at Carnegie Mellon University (CMU) have developed a system enabling smartphone users to tap their phone against Internet of Things appliances and automatically load a contextual menu onscreen. Their Deus EM-Machina system harnesses electromagnetic noise discharged from everyday electrical objects to power a device classifier, facilitating contextual functionality directly to the smartphone screen so it can serve as a dynamic control device. The project is part of the CMU Future Interfaces Group's work with wearable devices, extended to a more accurate form factor, says CMU professor Chris Harrison. "Unlike a smartwatch, you perform distinct activities on a smartphone," Harrison notes. "It's more of a tool than an accessory." The 12 example applications the team built for the technology include thermostat control, router configuration, document printing, and mobile-to-desktop text transmission.

May 25, 2017


In an interview, Dartmouth College's Jun Gong discusses Cito, an actuated movable smartwatch he designed with scientists from Dartmouth and other universities. Gong says the idea came from issues with current smartwatches, and he sought to provide actuation and movement to alert wearers of important messages. Gong proposed five specific movements--linear translation, rotating, orbiting around the wristband, lifting, and tilting--and over five months he generated ideas and interaction scenarios that were then engineered in a prototype. Gong says the Cito prototype serves as a proof of concept for users and other companies in the smartwatch industry. "I'm interested in how to design these interactions and how these interactions can help people, can allow people, maybe with no knowledge of device technology, to easily use this kind of device," Gong says. He presented the technology last month at the ACM SIGCHI Conference on Human Factors in Computing Systems (CHI 2017) in Denver, CO.
