NPointer is a free software to control your PC via gestures and voice. It uses a web camera attached to your PC or laptop and identify gestures that you make by your hands or head. It captures the movement and direction of your gestures and moves cursor accordingly. And when you want to click something at that point, just hold your hand and it will immediately show a menu to select various mouse operations you can do there, such as click, double-click, right-click scroll, etc.
You can also command this software via voice input. First you have to assign some voice notes to mouse events such as to click, double-click, drag-drop etc. Now when you speak that command, NPointer will identify it and will perform the action that is bound to it.
Control PC with Hand Gestures
NPointer lets you control your PC with hand gestures. As you move your hand in front of webcam, it will also move the cursor in the same direction. And when you want to click somewhere on the screen, just reach there and hold your hand. After sometime it will show you a group of options. You can click on the required option.
Instead of your hand, you can also use your head for making gestures. So, if you find it difficult to use your hand or you aren’t able to use your hand for some reason, then its a good alternative for making gestures.
Make sure that there is enough light in he room other wise the frame rate will start decreasing and then gesture will not be recognized accurately.
Control your PC with Voice Commands
Another noticeable feature of NPointer that is quite interesting is, it lets you control your PC via voice. To do this, you have to first feed a voice note sample in the software for all the mouse events like, click, double-click, scroll, drag-drop, selection.
Once you have specified all the voice commands, you can use them or change them later. To use voice commands instead of hand gestures, you have to un-check the Camera Control and check the Voice Control option. So, in this way you can control PC via voice commands.
This method didn’t work very precisely for me; probably it needs more training for voice recognition.
Customize Gestures Settings
In NPointer you can control many parameters of the gesture control. You can control the speed of movement, delay between opening action menu and idle gesture, etc. There are some custom preferences that NPointer gives you. If you don’t want to modify them, let them be as software defaults.
- Motion speed: To control the relative motion of gesture and mouse cursor.
- Acceleration: It is used to accelerate the pointer speed when hand gesture’s speed changes.
- Menu Timeout: It controls the time delay between appearance of action menu and hold
- Movement cut-off: It is used to specify how fast your hand should move in order to ignore the movement. This is useful in case where your hand needs to be removed from camera’s frame to keep the pointer idle.
