The Pointing Magnifier is a two-stage pointing technique. During the first stage the user controls an area cursor of arbitrary size depending on the pointing accuracy of the user. To interact with a target, the user places the area cursor over that target and activates it by clicking any mouse button. This causes everything under the circular cursor to be magnified, and the cursor is pinned in place. While magnified, the user controls a standard mouse pointer inside the magnified area. Upon performing an action (e.g., clicking, dragging) in magnified space, the pointer’s location is transposed so that the interaction occurs at the correct position in unmagnified space. After the user performs an action, the Pointing Magnifier returns to its original size and the user resumes control of the area cursor.
There are currently a few known issues which we have documented in deploying the Pointing Magnifier to Windows, however most functions are fully supported.
