8A. Driver 1620 would interpret taps within the particular icons of FIG. 8A by sending corresponding alerts known to be recognized by the software application, such as simulated keystrokes or mouse clicks. Driver 1620 may implement a mechanism to allow users to associate particular icons or auxiliary screens with pre-existing purposes.
In such devices, a finger faucet could trigger an activated operate whereas a pen tap can be interpreted as a normal mouse click on, or vice versa. Or, a particular button could possibly be supplied on the body of the pen that triggers the activated function of an icon when pressed. Yet one other mechanism is for the person to click on a soft button or icon on the main display to activate the touch display. home theater projector are well-known that could serve for touch display activation, such as finger movement gestures, voice instructions, foot switches, retinal gaze tracking, and so forth. Software functions that make use of the contact display can offer further, application-specific activation mechanisms. Icon 412 is a steady show of the time and date.
Alert dialogs can confusingly obstruct the view of the very operation that caused the alert, and are another good candidate for shifting to the touch display screen. Applications often name on commonplace operating system services to display alert dialogs, so the duty of shifting alerts to the touch display screen could be completed within the working system with out the cooperation of individual software program functions. Similarly, many computer techniques can play audio from music CD's. Users sometimes take heed to CD's as background music whereas doing unrelated work on the computer. CD enjoying software program sometimes displays a management window very related to that of the DVD software.
A visual conference could also be used to indicate which icons characterize tap-sensitive areas; in the instance of FIG. 4, dashed lines 426 and 428 are used to indicate these areas. In example image four hundred, additional icons have been added to symbolize various system status indicators and functions. Icon 410 defines a second contact area or a nook tapping region to activate the “back” operate of internet browsers and other software program.
This window can impede the applying for which the enter is intended. According to the present invention, the input technique dialog may be applied as a pop-up image on the touch screen. One in style input methodology is handwriting recognition, by which case the touch display can even serve as the handwriting enter device for added benefit.
A further disadvantage of prior artwork touch pads is that they burn up a major fraction of the floor space of the computer for a single devoted input function. Computer keyboards historically embrace a numeric keypad, however portable laptop keyboards hardly ever have room for a standard keypad. Portable pc system designers are compelled to undertake awkward options such because the “Fn” key. A pop-up numeric keypad screen similar to the calculator of FIG. 12 might serve the position of the numeric keypad in a portable laptop.
8D illustrates yet one more potential application involving word processors, such as Microsoft® Word, and doc viewers, such as Adobe Acrobat®. These software tools typically display auxiliary data similar to a desk of contents or a set of thumbnail web page photographs to offer context along with the main page or pages on display. This auxiliary info adds litter and takes up house that could otherwise be dedicated to web page viewing. 8D, auxiliary data 862 has been moved to the touch display screen 860, leaving extra room on the main show for page viewing. Corner faucet regions 866 and 868 have been retained however their capabilities have modified to features better suited to the document viewing software; region 866 selects the previous web page and region 868 selects the next web page. Scrolling area 870 has been retained from the default iconic display screen, as scrolling is a vital function of a document viewer.
The software program creates an ordered record of potential matches, that are displayed in space 1404. The consumer can touch one of the match characters in space 1404 to “type” the chosen character into the appliance operating on the principle display. Area 1406 accommodates touch-sensitive buttons to manage the character recognition software in numerous ways. 12 illustrates a pop-up calculator utility that operates entirely within the contact screen. Image 1200 contains the familiar numeric display 1202 and a matrix of buttons 1204 of a calculator.
