A recent article in the International Journal of Medical Informatics that explored the perceptions, attitudes and concerns of elderly persons towards wireless sensor network (WSN) technologies for healthcare found that the participants' attitudes toward the idea of wireless sensor networks for health monitoring were generally positive.
While the study's abstract is scant on details, some general findings included: that independence is "highly valued" and so any system that can prolong it is highly regarded; that privacy of the health data collected and transmitted might not be as important as typically considered; that cost may be the most important determinant influencing the acceptance of the technology.
