The Acer Aspire One laptop comes with a built-in webcam that is compatible with any webcam software. However, webcam software does not come pre-installed on the Aspire One. If you'd like to use your webcam for video chatting, you should download and install a program like Skype. But if you'd like to just test the webcam on your Aspire One, "WebcamMax" is the way to go.
Download and install the WebcamMax software. You are given a free 30-day trial, which will be more than enough to test out your webcam.
From the "Start" menu, launch WebcamMax. WebcamMax should automatically detect your webcam; when the program starts up, you should see yourself in the window in the upper-left corner of the program.
Click the Camera button located under the window to take a still photo, or the record button to record a video.
