At the Global Conference on Consumer Electronics 2017, in a paper entitled “An Approach to One-Point BodyBraille,” we reported that users can distinguish between three different vibration patterns using one vibration speaker. As with two-point Body-Braille (BB), we now extend one-point BB by introducing a fourth vibration pattern, i.e., a short-duration vibration (referred to as “none”), which yielded a correct answer rate (CAR) of 67%. To improve one-point BB’s CAR, we then consider four sets of vibration patterns. The introduction of vibrations that alternated between 150 and 40 Hz for the “both” vibration enabled our experiment’s participants to identify that pattern more clearly, thereby improving the CAR to 87%, which is equal to that of two-point BB. Based on the experimental findings, we successfully realized one-point BB.
