Eating Study
​
We performed an in-lab experiment where participants were requested to wear two wrist-worn sensors (Microsoft band 2), one on each hand, while following an eating and activity protocol. We recruited 15 participants, 7 male and 8 female. The mean age of the participants was 31.5 years (ranging from 21 - 63 years). Two participants were left-handed. The par- ticipants were scheduled to come into the lab on two separate occasions, once for breakfast and another for lunch.
We asked the participants to perform activities that involved eating using different methods, both using utensils (fork and knife, fork alone, and spoon alone) and eating with their hands. Intermittently they were asked to perform other activities such as: have a conversation, make a phone call, put on and off a pair of sun glasses, walk around the room, and type on the keyboard. The participants were requested to focus on eating, unless they felt discomfort, and in the event that a participant was full, they were given the opportunity to take a break and continue after the break. If they could not eat more food, we made sure to weigh the remaining food to estimate the amount of food consumed during the meal.
