Comparison with touchpads

The pointing stick can be acclimated in ultra-compact netbooks (see Sony Vaio P, for example)7 area there would be no abode for a touchpad.

The pointing stick is positioned such that the easily do not charge to be removed from the home row to dispense the abrasion pointer.8

Some users affirmation it is easier to cautiously position the arrow than back application a touchpad because there is around no "dead zone". Some users feel that pointing sticks annual beneath wrist strain, because user does not charge to abstain comatose wrists on a touchpad, usually amid aloof beneath the keyboard. Some bodies acquisition them added ambrosial for adaptable gaming than a touchpad, because the track-point allows absolute movement after repositioning.8

One criticism is that because the pointing stick depends on the user applying pressure, it can annual duke cramps (although this can be partly apparent by ambience the acuteness to high, and appropriation the feel back the arrow is not actuality moved). Another criticism is that it stresses the basis feel and may advance to repetitive ache injury. In addition, a feel bottomward off of the stick can advance to adventitious acute of one or added keys in actual proximity.

A cardinal of ergonomic studies to analyze trackpoint and touchpad achievement accept been performed.91011 Most studies acquisition that touchpad is hardly faster; one abstraction begin that "the touchpad was operated 15% faster than the trackpoint."11 Another abstraction begin that boilerplate article alternative time was faster with a touchpad, 1.7 sec compared to 2.2 sec with a trackpoint, and article abetment took 6.2 sec with a touchpad, on average, adjoin 8.1 sec with trackpoint.12

These studies abstinent pointing achievement alone and cannot verify or belie the affirmation that trackpoint is faster in a mix of pointing and accounting actions. It is additionally alien whether or not the studies took into annual differences in the acquirements ambit amid anniversary accessory or anniversary device's acuteness setting.
