We present the results of an empirical study investigating the effect of visual feedback and body postures on gesture interaction techniques in a dual task setup found, for example, in wearable computing. The conducted experiment uses a novel apparatus called "Hot Wire" that allows retaining the properties of wearable computing even in laboratory environments. Visual feedback was found to impair user performance and caused users to be caught in an attention demanding closed feedback loop once presented in a head-mounted display. Even though continuous feedback was not necessary for gesture interaction, users were unable to ignore it and remain focused on the primary task. The design of an alternative gesture recognition method using a body-centric frame of reference instead of a conventional static one to improve usability, is shown to have an opposed impact both on the performance and subjective perception of users. The presence of novel devices in gesture interaction, such as data gloves, is found to be a major source of erroneous gesture recognition due to unpredictable user behavior. Our detailed result discussion provides guidelines for designing better gesture interaction.
