Abstract

A portable computing device with a microcomputer, a first display, a magnifying optical element through which the first display is viewed to provide a user with an enlarged virtual display, a first input device to communicate with the first display, a second direct display, and a second input device that can be a keyboard such that the second display can interact with the keyboard to display alphanumeric and other symbols so the user can see what is being typed. The second display is directly viewed and is configured to display the same data being entered in the selected field of the first display. Typically, the first display is a liquid crystal color display, capable of displaying a full range of text and graphic images such as can displayed on a conventional computer monitor. A virtual image of the first display is viewed by holding the lens close to an eye. To a user, the virtual image appears as large a real display provided on a conventional desktop or laptop.
