The researcher's new study showed that by using ultrasound imaging in future wearable devices such as smart watches senses hand movements. The research team presented their work in worlds most important on human-computer interfaces, ACM CHI 2017 held in Denver, USA.

The research team from the Bristol Interaction Group (BIG) at the University of Bristol led by Professor Mike Fraser, Asier March and Jess McIntosh in collaboration with University Hospitals Bristol NHS Foundation Trust (UH Bristol).

Now a day's, computers are growing in number and wearable computers, such as smart watches, are gaining popularity. Beyond from smart watches, devices around the home are also on the increase as WiFi light bulbs and smart thermostats. However, current technology restricts the capability to interact with these devices current technology.

As an intuitive and easy way of interacting with and controlling smart devices in different surroundings, hand movements could suggest. For example, to dim the lights in the living room or to open or close to window a gesture could use. Even though the hand gesture is recognized in many ways, the major restriction is the placement of a sensor and often rules out certain techniques.

Smartwatches are becoming a leading wearable device. However, this device allows putting sensors in it to sense the hand gestures. The researchers saw the potential use of ultrasound imaging in pregnancy. So that the researchers suggest an ultrasonic imaging of forearm used to recognize hand gestures.

The research team categorized muscle movements as gestures by using image processing algorithms and machine learning. To find the best sensor placement for this technique, also carried user studies. Significantly, the results showed this sensing method worked well at the wrist and showed very high accuracy. An ideal sensing method allows future wearable devices to combine the ultrasonic technique to sense gestures.

A small, portable ultrasonic imaging sensor integrated into a smartwatch prevented due to many practical issues with current technologies. However, this smartwatch study is the most accurate method for detecting hand gestures.
