FunctionalityBearbeiten
Using Enable Viacam with a standard WebCam that should be able to produce 30 frames a second it is possible to translate head movements into movement of the mouse pointer. The movements don't need to be big, in fact tiny movements work very well, too.
It is possible to define an area in which the program looks for movement.
Additionally Enable Viacam offers click-support. It shows the so-called click-window at the other edge of the screen and shows several buttons to activate or deactivate automated clicking as well as buttons to choose what kind of click the user requires, be it right, left, double clicking or click-and-drag. to fundamentally activate the click-window, it has to be activated inside the program options.
Enable Viacam utilizes the so-called dwell-click. To perform a click the user just has to stop moving the mouse pointer and wait for a short period of time (the amount can be defined within the program's options). Since it can be a little difficult to stop movement the options menu contains a function that helps performing this task by simply defining a dead zone.
Enable Viacam can be used within computer games, even in shooters though it might be a bit problematic to use the click-window as well.
For beginners it might seem impossible to move the mouse pointer accurately but I can assure you that it is just a matter of training and a finding the correct settings. Just don't give up right away. Small movement can be achieved by nodding up, down, left or right.

some adviceBearbeiten
- some games have problems with eViacam's clickbar when it comes to fullscreen mode. In such cases it is advisable to switch off the clickbar.
- to grant good performance it is necessary that the WebCam can see the user properly. Make sure the room is bright enough.
- Frame rate will increase significantly when unneeded driver functions of the WebCam are disabled. Don't use picture optimization, color or brightness boost. Automatic exposure can kill frame rate.
