This paper discusses the possibilities of exploring new ways of expressing emotions with wearable technologies. In the paper, the terms 'wearable technologies' and 'wearables' are used to refer to garments and accessories that have embedded smart technologies with the ability to connect to an electronic network and the ability to create customisable, dynamic and interactive responses. People mostly communicate their emotions by observable bodily reactions such as facial expressions, gestures, and body movements. Visual expression of emotion can be augmented by adding artificial visual responses to the physiological visual responses of the body with garments and accessories. Wearable technologies define a new experience of clothing with the possibility to create interactively changing appearances. The dynamic visual compositions defined by the user, and provided by the computational processes, can enhance the abilities of the user for the expression of emotions.
