Referring to FIG. 1, a handheld computer 100 is depicted, being optionally detachably coupled to an accessory device 110, according to an exemplary embodiment. Handheld computer 100 may include Palm style computers manufactured by Palm, Inc., of Santa Clara, Calif. Other exemplary embodiments of the invention may include Windows CE™ handheld computers, or other handheld computers and personal digital assistants, as well as cellular telephones, and other mobile computing devices. Further, handheld computer 100 may be configured with or without accessory device 110 or optionally with any of a variety of other accessory devices. As shown, accessory device 110 may be, but is not limited to, a desktop cradle used for synchronizing with a personal computer or other device.

Preferably, handheld computer 100 includes interactive hardware and software that performs functions such as maintaining calendars, phone lists, task lists, notepads, calculation applications, spreadsheets, games, and other applications capable of running on a computing device. Handheld computer 100, shown in FIG. 1 includes a plurality of input functions, keys 117 and a display 113 having graphical user interface features. Display 113 may be provided with an interface that allows a user to select and alter displayed content using a pointer, such as, but not limited to, a stylus 200, an example of which is depicted in FIG. 2.

Referring again to FIG. 1, in an exemplary embodiment, display 113 also includes a Graffiti™ (or other handwriting recognition software) writing section 118 for tracing alpha-numeric characters as input. A plurality of input buttons 119 for performing automated or preprogrammed functions may be provided on a portion of display 113. In a particular embodiment, display 113 is a touch screen display that is electronically responsive to movements of a stylus on the surface of display 113.

Accessory device 110 may be one of several types of accessories, such as, but not limited to, a desktop synchronization cradle device for serial and/or wireless data communications, a Universal Serial Bus (USB) device, or other communication device. Accessory device 110 may include one or more ports for parallel and/or serial data transfer with other computers or data networks. Handheld computer 100 may use the accessory device 110 for the purpose of downloading and uploading software such as, but not limited to, game software and for synchronizing data on handheld computer 100 with a personal computer, for example. In an exemplary embodiment, accessory device 110 couples to handheld computer 100 through an electrical connector located at a bottom portion of handheld computer 100. Button 155 on accessory 110 may effectuate an electrical connection between accessory device 110 and handheld computer 100 when the two are connected.

In an exemplary embodiment, handheld computer 100 may include an integrated joypad 125. Integrated joypad 125 may be a finger or thumb actuated button (see FIG. 3) which is moveable by a user in a plurality of directions. For example, integrated joypad 125 may be moveable in the up and down direction. In an alternative embodiment, integrated joypad 125 may be moveable in an up and down direction as well as a left and right direction. Further still, in an alternative embodiment, as indicated in FIG. 6, integrated joypad 125 may be moved in eight discrete directions, including up, down, left, right, and diagonal directions. For example, if one defines the right-hand direction as a reference (0°), the button may be moveable in the directions corresponding to 0°, 45°, 90°, 135°, 180°, 225°, 270°, and 315°. Yet further still, joypad 125 may be configured to be moved in a continuum of directions from 0-360 degrees and communicate an analog signal to computing electronics of handheld computer 100. Joypad 125 is electronically coupled to computing electronics and/or data processing electronics that are disposed within a housing 130 of handheld computer 100. Joypad 125 is configured to communicate an electrical signal to the computing or data processing electronics of handheld computer 100. The electrical signal corresponds to the direction in which the joypad is pressed.

In an exemplary embodiment, joypad 125 is integrated into handheld computer 100 such that it is movably supported by housing 130 or such that is movable within an aperture in housing 130. Because joypad 125 is configured to communicate directional input by a user in a plurality of directions, joypad 125 is useful as an input device for game programs or other applications which may be running on handheld computer 100 and for navigating around display 113.

Conventionally, for gaming, users utilize a plurality of keys 117 integrated into the housing of handheld computer 100 for providing directional input. However, keys 117 do not enable a user to provide a plurality of directional inputs, nor is there a direction (or location) associated with each key that is intuitive to a user in a way that a joypad such as joypad 125 or a joystick provides. Further, conventionally, users utilize a combination of inputs on a touch screen by a stylus as well as directional inputs from a plurality of buttons such as buttons 117 (see FIG. 4) and directional buttons such as up and down buttons which may be conventionally integrated into handheld computer 100 for providing input to application programs and for navigating around display 113. Therefore, an advantage of providing an integrated joypad is that it provides a simplified directional input device for handheld computer 100 while requiring only a small amount of space (real estate) on housing 130, which is a common constraint of handheld computing devices.

In an exemplary embodiment, joypad 125 also includes a receptacle 128 for coupling of a graspable portion 230 (see FIG. 3) extending from joypad 125 to form a joystick device. Receptacle 128 may include, but is not limited to, a threaded aperture, or any other type of mechanical connection configuration allowing relatively simple attachment and detachment of a graspable (joystick) portion 230 therefrom.

Referring now to FIG. 2, stylus 200 is depicted. Stylus 200 includes a body portion 210, an end portion 220 and a tip portion 230. During conventional use, a user grasps body portion 210 and writes with tip 230 on a touch screen, such as touch screen 113 (FIG. 1). In an exemplary embodiment, tip 230 and/or end 220 may be removed from body 210 by, for example, unscrewing tip 230 or end 220 from body 210. Tip 230 includes a threaded portion 235 for coupling and decoupling from body 210. Shaft 235 may include any of a variety of coupling and decoupling structures, such as, but not limited to clips, balls, and other type of fastening structures. In an exemplary embodiment, either tip 230 or end 210 or any other section and/or portion of stylus 200 may be utilized as a graspable portion of a joystick which is inserted into receptacle 128 of joypad 125 as depicted in FIG. 3. Further, receptacle 128 may be configured to receive any of a variety of other graspable portions, such as a dedicated joystick handle, a pen tip, or any of a variety of other substantially stiff elements that may be used as a graspable portion for a joystick.

FIGS. 1, 4, and 5 depict handheld computer 100 with tip 230 coupled to receptacle 128 of integrated joypad 125 such that the combination of joypad 125 and connected stylus tip 230 forms a joystick that is provided for directional input to handheld computer 100. A user is able to control the movement of tip 230 with a single finger, multiple fingers or any parts of the hand. As tip 230 is moved in a direction (as depicted in FIG. 5), joypad 125 is similarly tilted in the same direction and effectuates an electrical signal.

During use, should a user wish to transition from using the stylus as a writing or pointing device for handheld computer 100, a user detaches tip 230 from stylus 200 by unscrewing tip 230 from body 210. The user then screws threaded portion 235 of tip 230 into receptacle 128. Receptacle 128 preferably has a screw thread therein configured to accept threaded portion 235.

While the detailed drawings, specific examples and particular formulations given describe exemplary embodiments, they serve the purpose of illustration only. The hardware and software configurations shown and described may differ depending on the chosen performance characteristics and physical characteristics of the computing devices. For example, the type of computing device, input device buttons, or configuration used may differ. The systems shown and described are not limited to the precise details and conditions disclosed. Furthermore, other substitutions, modifications, changes, and omissions may be made in the design, operating conditions, and arrangement of the exemplary embodiments without departing from the scope of the invention as expressed in the appended claims.
