TABLE 2.

Sense of control scale (SCS) including scale step descriptions.

SCS rating	Scale description
1	No control	Unintended direction
2	Almost no control	Cursor sometimes still	Heavy resistance
3	Little control	Cursor jittery
4	Some control	Can sometimes reach target
5	Almost full control	Right direction	Cursor imprecise
6	Full control

Note that the primary, most frequent descriptions (the first column of scale descriptions) appear to be somewhat general and directly related to the experience of control whereas the secondary, less common descriptions (the latter two column) appear to be more task specific and more often related to cursor accuracy.
