Searching For a Fix to nreliable Nutritional Research
Researchers hope using Google Glass to monitor subjects' food intakes will be more accurate than having them record their consumption in a diary.

Researchers at the University of Massachusetts Medical School have received a $1-million U.S. National Science Foundation grant to develop a system that can improve food intake accuracy by using Google Glass to record what participants consume, and then uploading the data to the cloud.
The Flexware pilot study will compare the results of trials in which participants will first use 24-hour diet recall, and later use the Google Glass.
"We are testing to see if using the Google Glass is an acceptable, feasible, and more accurate method to document food intake as compared to traditional food diary tracking," says lead investigator Yunsheng Ma. He says the program will have participants push a button to record video and audio that can enhance the estimates of what they ate.
Ma also is collaborating with three computer scientists on the system's development.
In an ideal scenario, the recorded video and audio files would be automatically uploaded to the cloud when the device is connected to Wi-Fi.
Among the issues that must be addressed before Flexware is ready to systematically retain and transfer large volumes of data are concerns over cybersecurity. Ma says the plan is to blur the human body in the video after the participant records the food and uploads the data.
