Embodiment Construction

[0016] refer to figure 1 , an electronic device according to the present invention is generally indicated by reference numeral 10 . For example, device 10 may be a handheld or palmtop computer, a personal digital assistant (PDA), or a mobile communication device such as a mobile phone. The device 10 is capable of storing and displaying data via a display or screen 12, which may be a liquid crystal display, a dot matrix display or a TFT (Thin Film Transistor) display.

[0017] Traditionally, a user of device 10 controls the data displayed on display screen 12 using a number of buttons 14 located on the device or using an input device such as a scratch pad or trackball. Optionally, many of these devices include a touch display, which allows the user to select options or change data on the display 12 using a pen-like pointing device, which is pressed on the desired location on the display, to select the desired option. Such a touch screen can only determine the two-dimensional...

Abstract

An electronic device (10) comprising: a display screen (12), used to display data stored in the electronic device (10); an input device (16); a detection device (20), used to detect the input device (16) a three-dimensional position relative to the device (10); and a control device for controlling the display on the display screen (12) according to the three-dimensional position of the input device (16) relative to the device (10) ) on the data. The input device (16) includes a source of electromagnetic radiation directing a cone-shaped beam of infrared rays towards the display screen (12). The detection device (20) can detect the elliptical eccentricity of the electromagnetic radiation incident on the display screen (12) to determine the angle at which the electromagnetic radiation is irradiated on the display screen (12), and can detect the incident The area of ​​electromagnetic radiation on the display screen (12) determines the distance between the input device (16) and the display screen (12).

Description

technical field [0001] This invention relates to computer navigation devices, and more particularly, but not exclusively, to such a device that facilitates navigation of software stored thereon even with a small display screen. Background technique [0002] It is well known to provide small handheld computer devices such as pocket organizers, personal digital assistants (PAD's), cellular telephones, and the like. The current trend is to make such devices as small as possible. Smaller devices are more portable and generally require less electrical power. [0003] However, a significant disadvantage of such devices is that the reduction in size necessitates a reduction in the size of the user interface, in particular the screen or display screen used to display the information or data stored or processed by the device. [0004] Many of these devices have the processing power of traditional desktops, laptops, or similar devices many times their size, and many products such as...
