Abstract

A handwriting capture system combines an image capture device such as a PDA, notebook computer, set top box, smart television, or other type of smart appliance having an image capture capability and a built-in wireless transceiver, with an ink capture device such as, for example, a digital notepad using, for example, electromagnetic, resistivity, or laser digitizing technology and presenting a suitable writing surface such as, for example, a paper writing surface for conventional ink. Communications between the ink capture device and the image capture device is achieved with wireless technology. For image capture devices such as PDAs and notebook computers having built-in infrared ports and designed for personal use, a portfolio is used to carry the ink capture device and the image capture device, and an infrared transceiver module with an infrared port cabled to the ink capture device is mounted on the portfolio so that the infrared port of the module is aligned with the infrared port of the image capture device when the latter is mounted in the portfolio. The image capture device is mounted on the portfolio with retainer clips or by any other releasable mounting technique so that…
