To determine whether tactile receptive communication is possible in both sighted and blind persons through the use of a mechanical device that creates the perception of continuous contact through sequential points of vibration on the skin and whether the ability of these two groups differs.
The cohort consisted of 20 sighted and 20 blind subjects who had no prior exposure to a tactile communication device that produces a tactile illusion. Each subject was presented number sequences created by the tactile illusion in the form of single-digit, three-digit, and four-digit sequences, and the number of trials needed for correct identification was recorded.
On average, the sighted subjects tended to identify the digit sequences sooner than did the blind subjects by almost one trial; however, this difference was not statistically significant. Younger subjects and female subjects also tended to identify the digit sequences sooner. Nevertheless, the overall correlation between age and number of trials across all replications was relatively minor.
Tactile receptive communication is possible through the use of a mechanical device used to create tactile illusions. The tactile illusion of numbers is equally perceived by blind and sighted persons.
通过使用一种机械装置来确定有视力者和盲人是否都能进行触觉感受性交流，该装置通过皮肤上连续的振动点产生持续接触的感觉，以及这两组人的能力是否存在差异。
该队列由20名有视力者和20名盲人组成，他们之前均未接触过产生触觉错觉的触觉交流设备。以一位数、三位数和四位数序列的形式向每位受试者呈现由触觉错觉产生的数字序列，并记录正确识别所需的试验次数。
平均而言，有视力的受试者比盲人受试者识别数字序列的速度快近一次试验；然而，这种差异没有统计学意义。年轻受试者和女性受试者也倾向于更快地识别数字序列。尽管如此，所有重复试验中年龄与试验次数之间的总体相关性相对较小。
通过使用用于产生触觉错觉的机械装置进行触觉感受性交流是可行的。盲人和有视力的人对数字的触觉错觉感知相同。
