Activities/hMouse
Introduction
hMouse allows to move the mouse pointer of the XO with the head or another body part. This is accomplished following a LED pointer with the camera. The LED pointer is attached to the head of the user using a very easy to made extra hardware. The h of hMouse comes from the English word 'head', but should be pronounced in Spanish, and 'Mouse' in English.
Usage
The LED must aim directly the camera and could, for example, be mounted in the user's right temple using a headband. To get optimal results the LED light must be high power (eg. 4.5 V), the user must be in a dark environment, with a uniform and opaque background, or by defect, use a translucid filter for the camera. The click must be done using other method, due the activity doesn't support this action yet. The program has a little help that explains quickly the steps to follow and then, each of it has its own instructions to guide the user trought the proccess. Also it has the option "Watch Camera", to allow watch what the camera is seeing, useful to test if the LED is correctly pointed and the user is in a favorable position.
First of all the user must calibrate the software. This must done because the distance and position of the user in face of the camera will change in each use, hence is necessary reconfigurate the image are in wich the program will search the LED.
