To me, the mouse just translates much better to the onscreen actions. A touchpad never feels quite right. Unfortunately it’s an inescapable necessity as the whole point of a laptop is to remain portable and fluid – tough then to always have the use of an external mouse.
Users of a similar situation are able to relate to the most annoying aspect when switching between a mouse or touchpad based interface – the precision or sensitivity are not transferable. That is, the movement of the cursor on screen in relation to the physical movement of the device, mouse or touchpad, aren’t related. As the freedom of movement with a mouse is greater, the sensitivity is usually lesser than that of a touchpad – which must incorporate an entire screen of movement in a 3″x1″ area. As you switch from device to device you likely need to then adjust the sensitivity with each switch as Windows has no built-in functionality like this.
AutoSensitivity is a free application that can adjust the sensitivity of your cursor based on whether a mouse is present on the system or not. Sitting in the tray, the utility will transparently make the adjustments for you once they’ve been set for each device. That’s effectively it for configurability, but what more does it really need?
Users who frequently encounter the above problem can set AutoSensitivity to start on boot, as well as minimized; meaning you won’t ever have to think about it again.
AutoSensitivity was tested under Windows 7 and requires the .NET framework, likely already available on your PC.
