The fast economy and technology development as well as the competitive markets nowadays results in high expectation on performance of employees in companies. Therefore, a working environment which can take care of the wellbeing of employees is important for an employee to stay healthy, enjoy his / her work and be able to develop himself / herself. In this paper we propose and demonstrate a design of a feedback system for body worn wireless sensors to be used in wireless emotion monitoring. Wireless sensors developed by Holst Centre IMEC NL has are applied to monitor physiological signals related to emotions. A prototype, the Smart Photo Frame has been made as the feedback device. This device provides employees feedback on the emotional arousal status in real-time, in an effort towards reducing work-related stressful states through positive calming. The feedback system is designed to be subtle in an office related environment. The prototype demonstrates the design concept and enables users to interact.
