A deep learning based wearable system for food and drink intake recognition

Abstract: Eating difficulties and the subsequent need for eating assistance are a prevalent issue within the elderly population. Besides, a poor diet is considered a confounding factor for developing chronic diseases and functional limitations. Driven by the above issues, this paper proposes a wrist-worn tri-axial accelerometer based food and drink intake recognition system. First, an adaptive segmentation technique is employed to identify potential eating and drinking gestures from the continuous accelerometer readings… Show more

“…Fifty-three unique devices and four combinations of devices ( 77 80 ) identified from 54 studies were included in the data extraction table ( Supplementary Table 1 ). Of the 53 unique devices, 18 devices were placed on the wrist ( 27 44 ); nine were worn around the neck ( 45 – 52 ); nine were placed in or around the ears ( 53 – 61 ); seven were glasses-like devices ( 62 68 ); and ten were categorized as “Other Devices” ( 30 , 36 , 69 76 ) where devices were worn in less common locations of the body or were non-wearable ( 69 , 72 ).…”

“…Therefore, a major advantage of wrist devices is the potential for it to detect both eating and drinking as it does not rely on chewing or swallowing activity. Both food and beverage intake were able to be identified in 5/18 wrist devices ( 27 , 33 , 37 , 40 , 44 ) and three of these could also distinguish between eating and drinking movements ( 27 , 33 , 40 ). The algorithms used by the wrist devices to detect HTM movements could be adapted to different handedness depending on the individual.…”

“…In wrist-worn-based approaches, individuals wear sensors on their right or left wrists to collect activity data. Detection algorithms are then applied to recognize drinking activities from the collected data [2,15,16]. In smart-container-based approaches, sensors are either attached to or embedded within a container to record data.…”
