Abstract
As examples for exploring the effects of the motion of artifacts in residential spaces on people's feelings, I created installations in the form of plants. I investigated whether the plant-like movement affected people's mood by evaluating the difference between participants' impressions of artifacts and the effect of the artifact's bio-likeness. I divided 42 participants into 'active mode' and 'still mode' groups. Participants would fill out the temporary mood scale before and 5 minutes after they enter the room. An impression evaluation questionnaire about the lighting fixtures should also be completed afterwards. An analysis of whether or not the presence of movement in a lighting fixture affected people's mood yielded the following results: (1) There was no interaction between the presence of movement and the pre- and postexperience mood states. (2) Participants in both groups increased their average mood score by over 7.5, but only those in the 'active mode' group reported an alleviation of anxiety and fatigue. An analysis between the impression evaluation of the lighting fixtures (with and without movement) and the impact of bio-likeness shows that (3) movement affects the impression evaluation of the three lighting fixtures and that bio-likeness is related to feeling and emotion.
