Evaluation of Appropriate Body Placement and Notification Modality of a Wearable Clip-on Notifier Using an Experimental Platform

We have designed and developed an experimental infrastructure capable of interacting with different wearable information terminals for delivery of timely push information based on the user profile. Focusing on the evaluation of the body placement, we have developed a wearable clip-on notifier which can be placed on different parts of the human body. It is a small accessory device capable of producing visual, buzzer-audio and tactile-vibrator effects with a natural and relatively small form-factor in a shape of a paper clip that can be attached or be worn as a pendant. In order to evaluate the best placement and modality for the clip-on notifier, we have selected a number of position candidates and have performed in-situ notification experiments while the subjects performed different activities. We have presented a good hierarchical system for subjective evaluation of the notifier placements, and our device was shown as potential solution for personalized information notification.
