Gateway P-172 Synaptics Touchpad Driver
You will find the build quality to be above average with durable plastics that are used throughout their chassis. The chassis of the notebook is also very rigid with very little flex on the palm rest.
Screen cover offers good protection and will show no ripples when you press your finger on the back of its LCD. It has an excellent contrast and color saturation features available from its glossy surface.
The direction of movement of the cursor is the same, with respect to X and Gateway P-172 Synaptics Touchpad axes, Gateway P-172 Synaptics Touchpad the direction of finger displacement. The program is arranged to operate in a continuous loop which, as can be seen in the Algorithm of FIG. It is noted that prior to initial depression of the touchscreen device the cursor is stationary on the display screen 16, and that it remains stationary at the moment that the touchscreen device 24 is first depressed.
Movement of the cursor does not commence until the user drags his finger along the touchscreen device Also, it is to be emphasized that with the arrangement of the present invention, it is of no significance as to what point on the touchscreen device 24 is chosen to be the point of first depression. The program accommodates any point on the screen with the exception of three special zones to be described below as a reference pointunlike many other touchscreen device applications, where the cursor usually jumps to the area directly underneath the user's finger when the touchscreen device is depressed.
Along with the establishment of the reference pointthere is automatically defined the "absolute mode zone" surrounding this reference point, as noted above, and movement of the user's finger within this zone results in movement of the cursor in the "absolute mode", i. On the other hand, movement of the user's finger across any of the four boundaries of the zone results in an automatic conversion of cursor movement to the "velocity Gateway P-172 Synaptics Touchpad, i.
Further in accordance with Gateway P-172 Synaptics Touchpad invention, there are provided at one, two or three locations on the touchscreen device, what are termed "mouse switch zones". The three zones are illustrated in FIGS. The Algorithm and program are arranged to recognize depression of the touchscreen device in any of these three zones, as the equivalent of a mouse "switch" function.
Typically mouse devices incorporate two manually activated switches as at 20 in FIG. In the Algorithm, these zones are collectively referred to as a "switch area". As an example, if the user depresses a point on the touchscreen device which is outside of this "switch area", then cursor control proceeds Gateway P-172 Synaptics Touchpad outlined above, namely, cursor movement within the "absolute mode zone" being proportional to finger displacement, and cursor movement outside this "absolute mode Gateway P-172 Synaptics Touchpad, being in a "velocity mode".
Further Normalization of the Data Base Relational Model.
After the cursor has arrived at the desired location, a mouse switch closure can be simulated Gateway P-172 Synaptics Touchpad the user merely Gateway P-172 Synaptics Touchpad his finger off the screen and momentarily depressing the desired area of the screen corresponding to mouse switch zoneor The program automatically converts this depression into a signal that is fed to the dedicated mouse port connector receptacleand which is read by the mouse port and computer as a mouse switch closure, not the screen depression which actually initiated it.
As an illustration of the various possible activities which can occur at the touchscreen device, several examples of operation will be reviewed, and with reference to the Algorithm of FIG. The boxes in the Algorithm of FIG.
Diamonds represent inquiries, whereas boxes indicate actions taken by Gateway P-172 Synaptics Touchpad program in response to a "YES" or "NO" answer to the inquiry set forth in the respective diamond. From the oval legend "START", referring to the boxwhen the touchscreen device 24 is first depressed at any random point Gateway P-172 Synaptics Touchpad the mouse switch zones,a reading of the location of the depression by X-axis and Y-axis coordinates is taken, and stored in the microprocessor 32 for use as the initial reference point If the user lifts his finger immediately, or Gateway P-172 Synaptics Touchpad after a short movement, then the answer to the inquiry in the subsequent diamond is "NO"; box indicates the result, namely that the program then halts the cursor, and readies it for subsequent movement in solely an "absolute mode".
Then the program reverts to the starting point, in readiness for the next depression. On the other hand, if the user depresses the screen and holds it, then the response to the inquiry of diamond is YES, and as a result the subsequent diamond queries whether this depression is within the mouse switch areaoror not.
Windows XP on the Gateway P-6831FX
If the response to this inquiry is YES, as a result of the depression being in Gateway P-172 Synaptics Touchpad switch area, then according to boxthe cursor is halted, the appropriate signal indicating activation of a mouse switch sent to the mouse port of the computer, and the program set in an "absolute mode" in readiness for the next depression, after the depression of the switch area is released. Alternately, if the continued depression is not Gateway P-172 Synaptics Touchpad the switch area, then the answer to the inquiry in diamond is Gateway P-172 Synaptics Touchpad the program then inquires Gateway P-172 Synaptics Touchpad the depression is the first time the touchscreen device is depressed.
In response to a YES answer, box indicates that the program then sets the initial point of depression as the reference point, establishes the boundaries of the "absolute mode zone"and directs the cursor to move in the absolute mode. In response to a NO answer, the program queries whether the point of depression has moved outside of the "absolute mode zone"as by the user dragging his finger. In response to a NO answer, the cursor would continue to move with finger displacement in an "absolute mode", as indicated by box In response to a YES answer, box indicates that the program would switch the cursor movement to a "velocity mode", wherein the cursor would move with a velocity that was proportional to finger displacement measured from the boundary crossing, as opposed to moving a distance that was proportional to finger displacement.
Naturally the user Gateway P-172 Synaptics Touchpad watch the cursor as it is being moved, and adjust his finger displacement as needed, to produce the desired response. It is to be noted that in an "absolute" mode, the cursor can be made to move a distance which differs from a strict 1: Other ratios can be chosen and incorporated in the program, to achieve different degrees of control, and depending on the requirements of resolution of movement of the cursor.
Gateway P-172 Synaptics Touchpad If a high degree of precision in the positioning of the cursor were desired, the program could be set for a high ratio of finger displacement to cursor movement, to permit precise positioning of the cursor on the display screen. The invention also embodies a novel and improved method of controlling the movement of a cursor Gateway P-172 Synaptics Touchpad means of a touchscreen device, as set forth below, and with reference to FIGS.
In the method of the invention, the cursor remains motionless when the pointing means 23 is first introduced to the screen 24, and prior to any displacement of the pointing means Also, according to the method of the invention, any point on the screen 24 can be selected as the initial reference pointsuch point being identified by a particular X-axis coordinate and a particular Y-axis coordinate.
