There are many ways to input text and sense movement in wearable devices, such as reference 1, which is using the movement detection to give feedback to

wearable device. It is not easy to sense the minor movement of fingers, especially during the night. Temperature sensing based on Phosphor thermometry doesn't depend on the visible light.

The problem is how to identify the input or operation gesture with temperature sensing in any environment with any kind of light, visible or invisible.

Disclosed is a input method and system to sense the temperature changes among finger nail and keyboard which are polished with nail enamel containing Phosphor(see reference 3). Phosphor materials, such as powder or nail enamel, are attached to finger or button in keyboard. With basic setting and keyboard sensing initialization in a wearable device, such as electronic glass, the layout of the fingers and keyboard can be confirmed by detecting the temperature distribution and identifying 2 or more exact location of buttons and fingers. What's is assumed here is only the finger which is hitting the button is deviated most within the normal range. Thus the temperature change in that area is most obvious, which can be used to decide which button are pressed. Further more, with only hands and fingers' action, the temperature changes can also be used as the operation gesture to wearable devices.

Advantages:
1. With the application of Phosphor thermometry on the finger nail, keyboard, or both, the electronic glass can identify the keyboard and fingers better by analyzing the range of temperature changes.

2. Temperature sensing can be used at night, which is better than visible light sensing.

3. Any keyboard with phosphor material affixed can be used by the electronic glass.

4. With fingers affixed phosphor material, users still can use fingers' temperature movement to input.

5. If the keyboard's button's labels are removed, the keyboard's layout still can be seen by wearing the electronic glass because they can still detect the temperature changes in the keyboard.

By detecting the range of temperature changes on the surface of fingernails, keyboard's button, or both,
