Mini Projector
15B illustrates an exemplary hardware structure implementing the security interlock of FIG. 15A. Computer system 1520 consists of contact display module 1522, which in flip accommodates the hardware and control circuitry illustrated in FIG. Touch display screen 1522 communicates to peripheral controller 1524. Controller 1524 also manages other peripherals 1526 such as keyboards, external pointing gadgets, and optional biometric authentication units. During portable projector of the pc, controller 1524 serves as a conduit between touch display 1522 and central processor 1528. Central processor 1528 in turn operates other gadgets 1530 such as the primary display and onerous drive.
The touch pad serves solely as an enter system for the pc. The contact pad functions primarily as a cursor pointing device, but some touch pads offer extra functions. Some software program functions already include detailed help textual content for many consumer interface elements. This assist text may be meant for show when the user invokes an specific context-sensitive assist command for the component. In the current invention, this pre-existing detailed help text can be tailored for show on the touch display screen as nicely, probably with little or no modification to the applying software itself. Some contact display screen applied sciences are sensitive to different objects, similar to a pen, pencil, or pointer, in addition to fingers.
8D illustrates one more potential software involving word processors, similar to Microsoft® Word, and document viewers, such as Adobe Acrobat®. These software program instruments often show auxiliary data similar to a desk of contents or a set of thumbnail page pictures to supply context along with the principle web page or pages on display. This auxiliary information provides clutter and takes up space that would in any other case be devoted to page viewing. 8D, auxiliary data 862 has been moved to touch display 860, leaving extra room on the primary show for web page viewing. Corner faucet areas 866 and 868 have been retained however their capabilities have changed to features higher suited to the doc viewing utility; area 866 selects the previous page and region 868 selects the following page. Scrolling area 870 has been retained from the default iconic display screen, as scrolling is an important operate of a doc viewer.
In an illustrative embodiment, a key on the main keyboard 104 of computer system a hundred of FIG. 1 is designated as the contact display screen activation key. 6A illustrates a portion 600 of the keyboard that includes several keys. power supply of the keyboard, similar to letter “Z” key 602, have preassigned features that do not overlap well with touch screen activation. All of the preceding examples have featured auxiliary screens tied to a specific application. It can additionally be possible for a particular window or dialog within an application to have an related auxiliary display screen.
1 replaces a conventional touch pad, touch screen 106 often serves as a standard pointing system for the computer. For this purpose, the contact screen must have the power to interface to the pc as a traditional mouse. This is an extra cause for interface 218 to be either a mouse interface similar to PS/2, or a general interface such as USB that features assist for standard mice.
The similar touch display screen can operate in each of those varied modes, or different modes, at totally different occasions. The different modes can also appear on the display on the identical time; for instance, icons can seem in an auxiliary or pop-up image, or an auxiliary or pop-up image could possibly be overlaid in a window on the iconic mode picture instead of absolutely replacing that image. The current invention discloses a graphical consumer interface in a computing system having a processor operating an operating system and a display. Driver 1620 might implement some icons, auxiliary screens, and pop-up screens entirely within the driver itself The driver might embody a mechanism for associating auxiliary screens with pre-existing applications that don't acknowledge API 1624. For instance, if a recognized pre-existing presentation software application has the input focus, the motive force might supply an auxiliary screen like that of FIG.
This icon would normally have no effect on the interpretation of finger faucets within its area. Instead, a finger tap inside its boundaries can be interpreted as a simulated mouse button click, simply as if the faucet occurred away from any icon. If each icon responded specially to finger faucets, the principle function of tapping to simulate a mouse click would turn out to be too inconvenient to use.
Because the number of candidate icons doubtless exceeds obtainable area, it might be desirable to offer a quantity of iconic display screen layouts selectable one way or the other similar to within the software program control panel or by tapping on an icon on the contact screen. Icon 424 represents the amount management for the sound system and speakers of the computer. Icon 424 features a visible slider and “thumb.” The position of the thumb on the slider displays the present volume setting.
