在 2017 年全球消费电子会议上,我们在一篇题为“单点 BodyBraille 的方法”的论文中报告说,用户可以使用一个振动扬声器区分三种不同的振动模式。与两点体盲文 (BB) 一样,我们现在通过引入第四种振动模式(即短时振动(称为“无”))来扩展一点 BB,其正确答案率 (CAR) 为 67%。为了提高一点 BB 的 CAR,我们考虑四组振动模式。为“两种”振动引入 150 和 40 Hz 之间交替的振动,使我们的实验参与者能够更清楚地识别该模式,从而将 CAR 提高到 87%,与两点 BB 相同。根据实验结果,我们成功实现了单点BB。
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.
