Abstract

Mobile devices are widely used through out the world. And now people spend lots of time on watching the mobile devices's screen like smartphones. Currently all the brightness adjusting of mobile devcies are only based on the Light sensor on the mobile devices. This solution does not consider the envirment near the people's eyes. This idea will consider both wearable device and mobile device's input and had provided a method to achieve a more accurate and suitable brightness for users when working on mobile devices. It takes not only the light intensity around environment into consideration, but also put emphasis on the real luminance felt by eyes. Brightness value from the two light sensor input sides will be adjusted according to policy to return user an already revised, thus more comfortable brightness. In order to adjust the Brightness of cell phone or pad in different conditions, it will consider using glasses to work with cell phone to determine the Brightness of cell phone. The Light Sensor in a phone can detect the light intensity around the cell phone, but usually there is a distance between the screen and human’s eyes, and they faced different direction so the light brightness will be possibly different.

A optimized method of brightness adjustment for mobile devices through wearable device

Mobile devices are widely used through out the world. And now people spend lots of time on watching the mobile device's screen like smart phones. Currently all the brightness adjusting of mobile devices are only based on the Light sensor on the mobile devices. This solution does not consider the environment near the people's eyes. In the past , it is hard to get the environment information near the eyes. And all the brightness adjusting is just based on the environment near the screen. This may make the brightness adjustment too dark or too light for the eye. Now more and more people use the wearable device like google glass, we can get both environment near the eye and near the screen and make the adjusting more accurate.

This idea will consider both wearable device and mobile device's input and had provided a method to achieve a more accurate and suitable brightness for users when working on mobile devices. It takes not only the light intensity around environment into consideration, but also put emphasis on the real luminance felt by eyes. Brightness value from the two light sensor input sides will be adjusted according to policy to return user an already revised, thus more comfortable brightness.

In order to adjust the Brightness of cell phone or pad in different conditions, we consider using glasses to work with cell phone to determine the Brightness of cell phone. The Light Sensor in a phone can detect the light intensity around the cell phone, but usually there is a distance between the screen and human's eyes, and they faced different direction so the light brightness will be possibly different.

In some circumstance, there many have different light source around a phone user and Light Sensor just aware part of the light. For example, as indicate in following picture, Light Sensor just aware the light source2, while light from source1 may go directly into a people's eyes and influence the feeling of brightness.

Here we introduce glasses with Light Sensor in it. As describe in following picture, the glass has a Light Sensor 2 and a communication module 3. The communication module can be a wireless module or Bluetooth. Light Sensor detect the light intensity that goes into people's eyes and send this information to cell phone via communication module.

Once the cell phone got light intensity information from the glasses, it will combine local light information with Light Sensor 1 to determine and adjust the brightness of the screen.

When a mobile device activate the screen, the Brightness Adjustment Module will try get light intensity value V1 & V2. If there is no input from Communication Module, that is the V2 is n...
