NUS Computing researchers develop wearable device for gait analysis

05 October 2020 Department of Computer Science , Faculty , Research , News Media , Systems & Networking

 

Three NUS researchers have developed wearable devices that help perform gait analysis. The four sensors installed at the toe and heel of the shoes can detect the speed, rotation and step length of the user's movement. The data is reflected in the app in real time for analysis by the therapist.

Dr Boyd Anderson, a lecturer from NUS Computing's Department of Computer Science, said: “If you are an elderly person, you may be more frail when walking, and being able to quantify that is very important. If you’re a sprinter, seeing how every step hits the track is also very important for say, optimising your performance. Traditionally, you would use a clinical gait mat which is pressure sensitive."

Medical gait mats take up space and are expensive, costing upwards of $10,000. The cost of this device however, is expected to be under $500. In addition to relying on an inertial measurement instrument to measure acceleration and rotation during movement, the device also combines ultra-wideband radio technology to collect step lengths and step widths that are difficult to measure. Its accuracy rate is 97%.

The four sensors mounted on the shoes run on lithium batteries and has a battery life of 18 hours per charge. The research team has already applied for a technology patent. They are working to bring this technology to professional athletes who are looking to improve their skills.

The team is also looking at ways to incorporate the sensors for use in various running shoes.

Life has a funny way of leading people down paths they least expect. Just ask NUS Computing lecturer Boyd Anderson. Two years ago, Anderson, then a PhD student, found himself at Mustafa Centre, a 24-hour mall in the heart of Singapore’s Little India district. It was 3 a.m., and Anderson was throwing what seemed to be a random assortment of things into a shopping cart: a hot glue gun, Velcro tape, disposable socks, and 12 pairs of sneakers, each a different size.

Don't Waste Food: Their App Lets You 'Dabao' Buffet Food For S$10, Buy Cheap Surplus Grocery

14 September 2020 Alum , News Media , Media

 

In 2019, Singapore generated around 744 million kg of food waste — that’s equivalent to two bowls of rice per person a day, or around 51,000 double decker buses.

Food wastage is a real problem — it does not only cause environmental problems, but also affects our food security and puts pressure on our resources.

When Preston Wong, 31, saw his family members clearing out excess expiring food items from the refrigerator one day, he wondered if a platform could be built to facilitate a redistribution of surplus food. He pitched the idea to his National University of Singapore (NUS) schoolmate, Kenneth Ham, 30.

The duo didn’t even share the same classes — Preston majored in law and accountancy, while Kenneth majored in computer science — but they knew each other from church.

In their final year at NUS, they decided to take the leap to develop an app to tackle food wastage in Singapore by reducing the amount of buffet food that’s thrown away at the end of the day.

How hackers use sound to unlock the secrets of your front door key

25 August 2020 Department of Computer Science , Faculty , Research , News Media , Security

 

A group of security researchers from the department of computer science at the National University of Singapore has created an attack model they call SpiKey to determine the key shape that will open any tumbler lock.

Soundarya Ramesh, Harini Ramprasad and Jun Han are the talented hackers behind SpiKey, which they say "significantly lowers the bar for an attacker," when compared to a more traditional lock-picking attack. The theoretical methodology is deceptively simple, listening for the sound of the key as it moves past tumbler pins in turn when the key is inserted in the lock.

The Singapore hackers use a simple smartphone to record the sound of the key being inserted, and withdrawn, with a smartphone and then observe the time between each tumbler pin click using their custom key reverse-engineering application. This forms the secret of the key, the fine-grained bitting depths which, the researchers report, can differ by as little as 15 milli-inches, or 0.381 millimeters.

"As SpiKey infers the shape of the key, it is inherently robust against anti-picking features in modern locks," the research paper states, "and grants multiple entries without leaving any traces."
