Initial User Evaluation for a Neck Gaiter for Tracing Swallowing Movements

This paper presents a design process, of a non-invasive neck gaiter for detecting swallowing movements. Previous studies have presented different solutions to detect swallowing movements, but according to our knowledge, none have integrated sensors into textiles. Moreover, the sensitive neck, and the thyroid area in particular, cannot be pressured with any kind of device, as it interferes with swallowing. Thus, devices used in the neck area must be comfortable. The gaiter was designed with an exploratory prototype, tested with a technical validation study, and finally, a feedback questionnaire was offered to participants. 17 participants submitted the questionnaire. The questionnaire results indicate the neck gaiter was relatively comfortable and soft; although the used Velcros were uncomfortable, and the gaiter disturbed turning the head. With the questionnaire, we identified the factors influencing user comfort during short-term usage and thus gained extremely important information for further development.
