Primer Streamer: a System to Attract Users to Interests via Images on HMD

Recently, environments in which users can always see information is becoming realistic due to the development of wearable computing. Researchers have proposed various information presentation methods for different situations. However, in wearable computing environments, since the user does not always need a particular piece of information, there should a specified duration for which the system can show information that does not have any specific importance for the user. In this research, we propose a system that prompts the user to become unconsciously attracted to certain information by presenting visual information related to their interest. Our system utilizes the concept of the priming effect, whereby individuals are affected by content that has been presented before. Evaluation results confirmed that presenting information prompts the user to obtain the intended information. We also implemented a prototype of the system, Primer Streamer, that presents information related to user interest.
