Evaluation of swallowing motion is necessary for preventing aspiration pneumonia. MRI and sound analyses are recent deglutition diagnoses, however, these are inherently susceptible to noise. We focused on the detection of skin motion around pharyngeal portion, and examined the feasibility of information measured by a depth camera. Firstly, we measured the pharyngeal portion in healthy subjects during the process of drinking water or saline. Secondly, we measured the pharyngeal skin during eating process of a piece of bread pasted with oil or with high viscosity gelatin. Results were as follows: a) we obtained the prospective self-gating of swallowing using depth information, b) the measurement is available for frequency analysis of the gating, and c) the deglutition was associated with the taste with respect to the sensory inspection. Consequently, periodical measurements by the 3-D depth camera might be useful for the selection of profiles corresponding to food intake including individual preferences.
