In order to achieve this, we developed a web-based touchpad designer,

where the user can fill in a variety of different parameters for a given

touchpad. We call this our “wizard.”

The wizard calls variety of back-end APIs that generate CAD drawings

essential for Cirque’s design process. From the moment the user finishes

their design to the moment the CAD files can be downloaded, fewer than

five seconds has passed for even the largest and most complex boards.

This type of speed not only saves Cirque many hours of work, but it also

allows them to iterate over any given touchpad design until it’s just right.

Our product provides Cirque with the capability of designing hundreds of

touchpads in a short amount of time, while also freeing up engineers to

focus on more specialized designs. We also developed the wizard in such

a way that it is extensible so that Cirque can easily add new sensors and

touchpad configuration in the future. Our hope is that Cirque continues to

build on what we have made for them so that in the future our product

can become an even more powerful tool at their disposal.

Cirque Corporation

The web-based touchpad designer, or wizard that we developed. It allows the user to enter in various board parameters to be converted to CAD drawings.

Cirque Corporation is the original inventor of

the capacitive touchpad that revolutionized

the way we interact with our computers.

These touchpads are complex and require

attention to detail during the design process.

That’s where we come in! TouchTech was

tasked with writing software to automate the

process of designing Cirque’s most common

forms of touchpads.
