摘要

我們反覆測量了兩位十多歲小女孩的手指識字能力，證實她們可以只用手指觸摸內容有文字或有圖案折疊的紙捲，而在腦中“看到”這些圖案之顏色及形狀。其中一位經過145次的實驗，我們發現了成功的幾項要件：小女孩手掌的溫度必須低於34℃；手指必須直接接觸紙捲，若隔一塑膠盒成紙捲用膠帶封死，則成功機會大幅下降；若戴上眼罩或在暗室做實驗則顏色認錯的比例大增；主觀的知覺也會影響辨識的正確率。另外我們也歸納出小女孩腦中圖像顯示的顺序：當圖像在腦中出現後幾秒鐘，手掌也同時量到放電的現象，第一次放電會讓受試者在腦中看到一片單一顏色或成帶狀的多種顏色，然後顏色消失；待第二次放電時受試者會主述看到部份的字或彩色圖案出現，然後又消失。接下來每出現一次放電，圖案會重新出現並增加一部份內容又消失，直到不再增加爲止。我們推測受試者手指可能送出未知信號投射折疊紙張的表面，然後將反射之信號接收送回到視覺中樞而非觸覺中樞成像。
若能找這種信號發出及擷耳取之機制，仿製成新式的醫學儀器，則可以直接從體外掃描形成消化管道及內臟內外壁的影像。另外我們也可以訓練後天育的盲人，開發手指視覺，使其重新看到這個世界。

Repeated tests on two girls Just over 10 years old demonstrated that they could indeed ”see” the color and shape of the figures or characters in their brain by just touching a piece of folded paper containing these patterns with lingers. One of the girls was tested for one hundred and forty five times, and we discovered several requirements for the success of the experiments: first the palm temperature of the girl must he lower than 34 ℃. Second, the finger must contact the folded paper directly, if the folded paper is contained in a plastic box or stuck with tape, the accuracy rate drops significantly. Thirdly, the color recognition rate decreases appreciably when the test is performed in a dark room or the girl wears eyeshades. Fourthly, the girls' subjective cognition lends to affect the accuracy rate.
In addition, the figure emerging sequence in the girl's brain can he deduced: after the patterns emerge in the girl’s visual field for several seconds, we measure an electrical pulse generated between the girl's palms. The first pulse represents the emergence of a screen with single color or multicolor arranged in stripes in the girl's brain, then the color disappears. When the second pulse is detected, the girl describes that she sees part of the colorful character or figures appearing in her visual field, then the signals disappears again. Later on, the pattern will reappear with more content and then disappear until there is no more increase in content. We postulate that the girl's lingers may send some unknown radiation through the surface of the folded paper, then the reflected signals are detected and sent back not to the somatic sensory cortex hut to the visual cortex and the visual center reconstructs the image.
If the radiation and signal transmission mechanisms can he understood, a new type of medical diagnostic instrument can he designed to externally reconstruct the inner image of the inner organs of the human body. In addition, we can also train the blind people to develop this ”finger vision” and help them to ”see” this world again.
