A system for enabling user interaction with computer software. The system includes a printer for receiving print data, printing a form, using the print data, with information related to an interactive element coincident with coded data indicative of the interactive element, receiving indicating data from a sensing device which is generated by the sensing device sensing the coincident coded data so as to be indicative of the interactive element, and transfer the indicating data to a computer system to allow the interaction to be interpreted. The coded data is indicative of an identity. The computer system determines, using the indicating data, the identity, determines, using the identity, a page description, and identifies, using the page description, the interactive element.

The controller chip 134 is mounted on the second flex PCB 129 in the pen 101.
FIG. 10 is a block diagram illustrating in more detail the architecture of the controller chip 134. FIG. 10 also shows representations of the RF chip 133, the image sensor 132, the tri-color status LED 116, the IR illumination LED 131, the IR force sensor LED 143, and the force sensor photodiode 144.
The controlling processor 145 captures and decodes location data from tags from the surface via the image sensor 132, monitors the force sensor photodiode 144, controls the LEDs 116, 131 and 143, and handles short-range radio communication via the radio transceiver 153. It is a medium-performance (˜40 MHz) general-purpose RISC processor. The processor 145, digital transceiver components (transceiver controller 153 and baseband circuit 154), image sensor interface 152, flash memory 147 and 512 KB DRAM 148 are integrated in a single controller ASIC. Analog RF components (RF circuit 155 and RF resonators and inductors 156) are provided in the separate RF chip.
