Usability of Thermal Sensation Voting Device

Indoor climate has a key role on the performance of office workers. To assess the thermal comfort of a room, some models have been proposed. However, even with those models, manage and control all variables related to thermal comfort is a complex task. To simplify this process, a simple device that allows workers to vote if the indoor climate is "hot", "nice" or "cold", was developed, and a usability survey was conducted to evaluate how good the proposed user interface was. A poor feedback when voting and the lack of information about how the gathered votes were used to manage the indoor thermal comfort are some of the major findings from this survey.
