This study explores on emotion and perception of teacups in subject teams of sighted people and blind people through the tactile sense. Two subject teams are arranged individually to touch the teacups one by one separated by curtains in a room. After observing and investigating, PAD emotion scale will be applied to evaluate emotion of participants. The researcher explores whether haptic sense effect is produced from participants' tactual behavior with one set teacup. The finding is shown that: (1). The emotional effects of the blind sub- jects are more extreme than the sighted subjects in pleasure and arousal dimen- sions; (2). A teacup with oblique relief texture can make the unsighted subjects more pleasure emotions; (3). A straight line makes the blind subjects more un- certainty feelings and result in a negative emotional state; (4). Compare to the unsighted subjects, there is only a little difference between positive and nega- tive emotion in the pleasure state of sighted subjects.

That is the reason why researchers have taken much more time and energy devoting to the study of picture perception in vision than in touch [15]. However, affective expression of people is naturally communicated by multiple body sense organs [6]. Differently, the blind must contact everything from tactile and hearing sense. Recent- ly, some researchers have represented that distinct emotions such as anger, fear, hap- piness, sympathy, love, and gratitude can be formed by touching communicating [9]. Moreover, the emotions communicated by haptic is commensurate to facial and vocal displays of emotion [10]. It is known that the blind will be more sensitive than sighted people caused by their impaired vision that resulting in penetrative tactile of hands. That is, to survey the tactile actions of blind people seems to infer their state of emo- tion and perception. In this paper, we engaged in participant-observation to observe and record beha- viors of subjects on touching with the teacups. Then we measure emotion and percep- tion of the tactile sense by using PAD model, validate PAD theory’s correctness and applicability in haptic area and verify its feasibility.
