One hundred and eight students participated in the experiment as subjects. There were nine subject-groups. K1, K2, K3, K4 and K5 were presented 48 Japanese Katakana letters, KL was presented 26 Katakana letters (the same as Loomis, 1990). A1, A2 and A3 were presented 26 upper case alphabet letters. Katakana letters were divided into 2, 3, 4 or 8 equal sub-sets in K2, K3, K4 and K5 respectively; alphabet letters were divided into 2 or 4 sub-sets. Each letter was presented once at each size (3.0, 5.5, and 8.0mm in height) to the right index-finger tip haptically. The hit rates of katakana letter were less than those of alphabet (p<.01). As the set-size grew smaller, the hit rate increased in both kinds of the letter (p<.01). The effects of letter-size were significant (p<.01) in any group. But, no significant difference could be found between hit rates of KL and those of K2. These results suggest that stimulus-set size should be considered a determinant in haptic recognition of letters.
