New York, October 29, 2016: Google Glass can make learning Morse code much easier as researchers have developed a system that teaches the code within four hours using a series of vibrations felt near the ear. Morse code is a method of transmitting text information in which letters are represented by combinations of long and short light or sound signals. Participants wearing Google Glass learned it without paying attention to the signals, they played games, while feeling the taps and hearing the corresponding letters.

After those few hours, they were 94 per cent accurate keying a sentence that included every letter of the alphabet and 98 per cent accurate writing codes for every letter, the researchers said.

“Does this new study mean that people will rush out to learn Morse code? Probably not,” said lead researcher Thad Starner, Professor at Georgia Institute of Technology.

“It shows that PHL (passive haptic learning) lowers the barrier to learn text-entry methods, something we need for smartwatches and any text-entry that doesn’t require you to look at your device or keyboard,” Starner said in a Georgia Tech statement. This is the latest chapter of passive haptic learning studies at Georgia Tech.

The same method, using vibrations while participants aren’t paying attention, has taught people braille, how to play the piano and improved hand sensation for those with partial spinal cord injury. In the current study, the team decided to use Glass because it has both a built-in speaker and tapper (Glass’s bone-conduction transducer).

In the study, participants played a game while feeling vibration taps between their temple and ear. The taps represented the dots and dashes of Morse code and passively ‘taught’ users through their tactile senses, even while they were distracted by the game. The taps were created when researchers sent a very low-frequency signal to Glass’s speaker system. Because it was played very slowly, the sound was felt as a vibration.

Half of the participants in the study felt the vibration taps and a voice prompt for each corresponding letter. The other half, the control group, felt no taps to help them learn. Participants were tested throughout the study on their knowledge of Morse code and their ability to type it. After less than four hours of feeling every letter, everyone was challenged to type the alphabet in Morse code in a final test. The control group was accurate only half the time. Those who felt the passive cues were nearly perfect. (IANS)

Wearable Technology Google Glass Teaches Children with Autism Spectrum Disorder (ASD)

Google Glass listens to conversations and prompts the user with an appropriate reply

Toronto, Sep 16, 2017: An app to be used with wearable technology such as Google Glass — a head-mounted display in the shape of eyeglasses — can coach children with autism spectrum disorder (ASD) in everyday social interactions, new research has found.

A defining feature of ASD is difficulties with social communication — which can include initiating and maintaining conversations with others.

“We developed software for a wearable system that helps coach children with autism spectrum disorder in everyday social interactions,” said Azadeh Kushki, Assistant Professor at the University of Toronto in Canada.

“In this study, we show that children are able to use this new technology and they enjoy interacting with it,” Kushki added.

Children with autism spectrum disorder are often drawn to technological devices and find them highly motivating tools for delivering interventions designed to help them.

The problem with existing technology, however, is that using human-to-computer interaction to teach social skills can have the opposite effect to its goal, in that the user becomes socially isolated.

“The interesting thing about our new technology is that we are not trying to replace human-to-human interactions; instead, we use this app to coach children who are communicating with people in real-world situations,” Kushki explained.

“Children can practice their skills outside of their normal therapy sessions and it can provide them with increased independence in everyday interactions,” Kushki added.

Kushki and her colleagues developed the app, named Holli, to be used with wearable technology such as Google Glass. It listens to conversations and prompts the user with an appropriate reply.

For example, if the user is greeted by a person who says ‘Welcome’, Holli will provide various responses to choose from, such as ‘Hey’, ‘Hello’ or ‘Afternoon’.

When Holli recognises the user’s response, the prompts disappear and Holli waits for the next exchange in conversation.

To assess the usability of the prototype software, the researchers asked a small group of children with ASD to be guided by Holli when interacting socially.

They saw that Holli could complete most conversations without error, and that children could follow the prompts to carry on a social interaction.

In fact, Holli was often able to understand what the user was saying before/he she finished saying it, which helped the conversation to flow naturally, the study said.

“This study shows the potential of technology-based intervention to help children with ASD,” Kushki said.

“These systems can be used in everyday settings, such as home and school, to reinforce techniques learned in therapeutic settings,” she added. (IANS)
