| 摘要 |
The invention relates to an apparatus for guiding a marker over a computer screen. The apparatus includes a housing (102) that has two mutually opposing main surfaces (3, 4), two mutually opposite side surfaces that bridge the main surfaces, and two mutually opposite end parts (6, 7). The housing (102) is dimensioned and shaped to be accommodated in one hand of a user, wherewith the housing (102) is provided with two switches (106, 108) in positions in which the respective forefinger and middle finger of the hand will overlap a respective switch when the thumb on said hand lies closely to the one, first, side surface (1) and the little finger, or pinkie, and ring finger of the hand lie closely to the second side surface (2). The apparatus includes a first guide device (104) which, in response to two-dimensional actuation, generates a control (guide) signal which can cause the marker to move correspondingly on the screen. |
