The PARCTab was similar in shape, size, and appearance to a [[PDA]] It had a touch screen and a stylus. It also had handwriting recognition.
The PARCTab had infrared sensors and emitters to communicate with 'gateway nodes' that were to be installed in a ___location. The notable feature of the PARCTab was its ability to offer different funcionality depending on where the user was using the device within the area covered by the gateway nodes.<ref name=computerhistory>{{Cite web |title=Xerox PARCTab Prototype - PDA - Computing History |url=https://www.computinghistory.org.uk/det/36785/Xerox-PARCTab-Prototype/ |access-date=2023-12-17 |website=www.computinghistory.org.uk}}</ref>
The PARCTab was developed around the same time as the [[Apple Newton]].<ref>{{Cite web |title=History of HCI |url=https://rauterberg.employee.id.tue.nl/presentations/HCI-history/ |access-date=2023-12-17 |website=rauterberg.employee.id.tue.nl}}</ref>
Xerox also designed a device called the PARCPad, which was like the PARCTab, but larger.
The PARCTab had a Motorola processor.<ref name=computerhistory />
