As adoption of the touchpad grew, Synaptics sought to integrate the technology with other products and expand the company with a range of human interface technologies. In 1999, Francis Lee took over as CEO. The company had an initial public offering in 2002. In 2004, Apple debuted the iPod Mini and fourth-generation iPod, both featuring a scrolling click wheel enabled by Synaptics' capacitive touch technology, and Synaptics also provided a similar, vertical solution for the click wheel of the Creative Zen Touch portable media player.
