<p>A method, apparatus, and signal-bearing medium that selects an object displayed on a display screen when a cursor controlled by a pointing device pauses at the object for a time period longer than a dwell-time threshold. The dwell-time threshold is adjusted based on the density of the objects displayed on the screen. Thus, when the density of displayed objects is higher, the dwell-time threshold is longer and the user must hold the cursor at the desired object for a longer time in order to select the object. Similarly, when the density of displayed objects is lower, the dwell-time threshold is lower, and the user must hold the cursor at the desired object for a shorter time in order to select the object.</p> |
