In this paper we investigate how people emotionally respond to the emotional expression of a plant when external stimuli were given to the plant. For this purpose we built a simple LED emoticon-based device as an emotional proxy for delivering inner states of a plant, assuming the inner states of a plant can be changed depending on either positive or negative external stimuli. Our pilot study suggests that people's attitude on plants can be influenced by observing the emotional expressions of a plant.
The purpose of this study is to identify the degree of direct human communication that is replaced by smartphone-based Social Networking Services (SNSs). To this end, we designed a device for intuitively playing a Phone Stack Game, and performed comparative analysis by examining the conditions before and after installation of the device through videos. Through the analytic results, we confirmed that direct emotional exchange is reduced by more than half when smartphones are used. This study is significant because it confirms that smartphones are replacing an existing emotional exchange method and that their effects are considerable.
