What does the 'Light Sensor' on the RF Keyboard/Mouse Receiver do?

First take a looky here if you're not familiar with the VGP-WKB1:
Manual: http://www.mgmi.fr/docs/pdfprod/MUVGP-WKB1.pdf
Product: http://tinyurl.com/5lmmp

On page 47 of the manual you will see it refers to the "light sensing portion" of the receiver (the round USB device) but doesn't think to explain what this does! Like a customer wouldn't wanna know. Pfft!

The Receiver itself communicates with the keyboard/mouse using radio waves, so why does it need to 'sense light'?

I posed this question to Sony support. I genuinely believe they have chimps operating the response computers. Here are some of the ludicrous 'guesses':

"The light sensor in the mouse you are referring to is responsible for the movement of the mouse. It is used instead of the Mouse ball." It's easy to mistake the mouse for the RF receiver, isn't it. Especially when the customer types "RF RECEIVER". God help us.

"We are glad to assist you with the information regarding the light sensor of the keyboard. A light sensor is a sensor that measures the amount of light that it sees. The light sensor uses its own light source, a red Light Emitting Diode (LED), to illuminate a small area in front of its receiver. This makes it possible to allow a communication distance of upto 32.8 feet. We suggest that you refer to the user manual for further information." Um, no, the RF receiver has no LED on it. It is a flat smooth grey slab. And they use radio to communicate. Not infra-red. Oh for the love of all that is holy.

So, can anyone tell Sony what they made a Sony product with a light sensing portion for?

Hi CJSnet,

This reply may be just as daft as the ones offered by support, but do you notice any change in screen brightness under different light conditions.

Some Vaio notebooks have an inbuilt light sensor that adjusts screen brightness to suit ambient light conditions – maybe your desktop model has a similar feature :thinking:

Great answer! Doesn't seem to have any effect though. You'd think they'd actually tell you what it's for in the product description or manual! Geez.
