Universal Stylus Initiative

The Universal Stylus Initiative (USI) is a non-profit alliance of companies promoting a proprietary technical standard for interoperable active pen styluses on touchscreen devices such as phones, tablets, and computers.[1]

It defines a two-way communications protocol between the stylus and the computer and allows the stylus to remember user preferences for ink color and stroke. Multiple styluses can simultaneously draw on a single device. It support 9-axis inertial measurement.[2]

As of 2020, access to the specification is only available to members, but the goal is to create an open, non-proprietary active stylus specification with a certification program for members.[3][2][4]

As of 2019, there were over 30 members including Google and 3M, but some major players like Apple and Microsoft had not joined.[2]

Products started coming to market in 2019 including one stylus and several Chromebooks from different manufacturers.[1]
