According to Canon, there are gyro sensors which detect unnecessary vibrations. This triggers the corresponding movement of correcting lens group which is perpendicular to the optical axis. This, then, alters the light path, which returns the image to its proper place on the film plane or sensor.

In using the 1/ focal length rule, Canon EF 70 300mm USM could be handheld at 300mm with 1/45 of a second shutter speed. There could be sharp handheld images that are consistently at 1/5 or 1/4 second shutter speeds at 70 mm, and at 1/25 second at 300 mm on a whole frame body.

The automatic tripod sensing will prevent feedback loops that usually occur between the image stabilizer sensors as well as stabilizer motor vibrations. This application if image stabilizer comprises of Modes 1 and 2 stabilizations. Use the mode 1 which is dual axis stabilization in shooting stationary subjects, while use the mode 2 for a single axis stabilization in panning on a moving subject. The image stabilization switches are recessed to avoid accidental changes, which is a nice improvement. People have said over and over again that image stabilization is the most wonderful feature of this camera lens. It is a great help especially when shooting stationary subjects without the use of tripod.

Generally, image stabilization is very helpful especially for a slow and lens with narrow aperture. But of course, slow is relative. The Canon EF 70-300mm apertures are typical for the consumer telephoto zoom lens. more info
