Hyperspectral Imaging for Macronutrient Detection

Hyperspectral Imaging for Macronutrient Detection

We are using a smart tray with pressure sensors to measure portion and bite-size. The tray looks like a regular dining tray, but contains multiple built-in weighing scales and a video camera. The device is unique in the sense that it incorporates automated measures of food and drink intake and eating behavior over the course of a meal.

Ear Mounted Accelerometry and Photoplethysmography Sensor

Ear Mounted Accelerometry and Photoplethysmography Sensor

Traditional eating behavior detection relies on video and manual annotation. Our approach uses machine learning with an ear-mounted sensor measuring accelerometry and photoplethysmography, offering a less invasive, more natural experience for participants.

Extended Reality (XR) for Nutrition

Extended Reality (XR) for Nutrition

Using applications designed with detecting eating behaviour in mind, we are exploring the power of using Virtual and Augmented Reality (VR/AR) to measure eating behaviours in real time, with lower cost.
