Most daily activities involve the manipulation of multiple objects, during which humans obtain information and regulate their movements over the course of these actions. For sighted individuals, the relationship between visual perception and bodily movements for manipulating objects is well-documented. In this study, we examined bodily movements and perceptions during the process of making instant coffee by individuals with visual impairments, using two tabletop designs. Experiment had a total of six participants. Participants with visual impairments tend to position objects in a way that reflects on their range of body movement, with those who are completely blind are particularly inclined to perform actions within the overlapping range of their arms movements. However, when tactile cues are incorporated into the environment, the range of object placement expands in some cases. In the analysis of a time series of body movements, “touching” and “movement changes” were observed in the switching between sub-goal units and trunk movements. These movement changes were inferred in the form of a fine-tuning of perception and movement without conscious awareness, as with microslips. Individuals with visual impairments orient themselves in the environment by trunk movements, locate objects by touching, and fine-tuning their perception and movement through movement changes. They perceive spatial configurations by coordinating their trunk, arms, and fingertips.
