Abstract

CHARACTER ENTRY STRIP FOR HANDHELD DEVICES

This text was extracted from a Microsoft Word 97 document.
This is the abbreviated version, containing approximately 100% of the total text.

With the growth of hand-held (mobile) devices like cellular phone, pager, PDA, a need for easy and small text input mechanism is growing. This invention proposes a new input device that lets user enter characters by sliding their finger on a touch sensitive strip.

Most existing character entry mechanisms on a handheld devices like small keyboard, touch pad/pen or track-ball requires both hands to be used while entering text. The character entry strip has an added advantage of requiring only one hand to enter characters.

The proposed input device consists of a touch sensitive rectangular area (the strip), wide enough to slide one finger and a display screen. The strip is marked with characters (see Figure 1). As user slides their finger on it, corresponding character is displayed on the screen. User then applies extra pressure on the strip to select the displayed character.

The character entry strip can be designed as a modular input device, that can be attached to any side of a hand-held device. Most hand-held devices have a display screen which can be used as the character display area. In such cases, mobile devices must provide an interface (like a port) to connect the strip.

Devices like Cellular phones, Two-way Radios, Two way Pagers, PDAs are perfect examples of how the character entry strip can be utilized to input text.
