Click, click, click, click, click.
With a hand resting on a desk, it is easy to have the accuracy needed to click on items.
The results show that the accuracy of mouse clicks and aiming speed are related the size of targets.
Knewton, started four years ago in New York City by the 43-year-old Ferreira, builds its software into online classes that watch students' every move: scores, speed, accuracy, delays, keystrokes, click-streams and drop-offs.
Precision demands were induced by reducing target size, increasing mouse gain, or by demanding a high level of clicking accuracy.
In the third category, i.e. increased precision demands, stressors such as high clicking accuracy (provoked by a reduced target size) and increased mouse gain are included.
