The USI 1.0 Specification provides independent hardware vendors (IHVs) and original equipment manufacturers (OEMs) for the first time an industry standard, non-proprietary, active stylus protocol.
EDITOR'S NOTE: I missed this story when it was released last month, but better late than never. It's also noteworthy to highlight that Microsoft and N-Trig are not part of this initiative.
Single USI Stylus Will Work Across Multiple Devices, Platforms
WAKEFIELD, Mass., USA – April 23, 2015 – Prominent OEMs, stylus and touch controller manufacturers today announced the launch of Universal Stylus Initiative (USI), a new organization formed to develop and promote an industry specification for an active stylus.
The USI specification will make it possible for manufacturers to design products to a single standard, rather than the variety of proprietary approaches now in use, and it will be compatible with current notebook computer operating system requirements. USI seeks to provide a consistent user experience while increasing the availability and consumer appeal of the active stylus, through providing industry-wide interoperability and adding functions and features not supported by current styluses.
Founding members of USI include Atmel Corporation; Hanvon Pentech Co., Ltd.; Intel Corporation; Lenovo Inc.; Sharp Corporation; Synaptics Inc.; Wacom Co., Ltd.; and Waltop International Corp. at the Promoter level; and Dell Global B.V.; eGalax_eMPIA Technology Inc. (EETI); Elan Microelectronics Corporation; and Focal Tech Electronics, Ltd. at the Contributor level.
USI technology will enable interoperable communication between an active stylus and touch-enabled devices such as phones, tablets, and computing and entertainment platforms from numerous manufacturers, allowing consumers to seamlessly write or draw on different devices with one high-quality stylus that delivers a realistic pen-on-paper experience. The group expects to publish the initial version of the USI specification in the third quarter of 2015.
“USI’s founding members have come together to enable interoperable active styluses that function across many content creation devices,” said Ajay Bhatt, Intel Fellow. “Our goal is to make the active stylus more affordable and widely available in the market. Consumers who buy USI-compatible devices will know that they work seamlessly with each other while providing a high-quality writing or drawing experience.”
“The market has sorely been needing a universal communication standard for active stylus,” said Jon Peddie of Jon Peddie Research. “To date the market has been limited by proprietary touch controller-stylus solutions, which limits OEM choices and cost reductions. With the USI specification released, we expect that the capacitive active stylus market will grow from 100 million units in 2015 to 300 million units in 2018, opening up new markets such as smartphones and all-in-one PCs.”
[Additional comments from USI founding member companies appear at the end of this press release.]
Features of the USI specification include the method by which the stylus communicates with content creation devices and provides additional information such as stylus pressure levels, button presses, erasing, and other features. Through the same sensor that one’s finger uses to command a device, the stylus communicates via different frequencies to perform the action of writing — writing with up to 2048 different levels of pressure to give the pen-on-paper experience and render thinner or thicker lines in note-taking, painting and doodling, just like an ink pen.
USI is currently accepting additional member companies who are ready to be hands-on in completing and promoting a specification to achieve active stylus interoperability. USI welcomes any organization that wants to be involved in this industry initiative. Several membership levels are available.
About Universal Stylus Initiative
Launched in 2015, Universal Stylus Initiative (USI) is an international not-for-profit technology trade association whose mission is to define industry-wide standards for interoperable communication between an active stylus and touch-enabled devices such as phones, tablets, and computing and entertainment platforms. The USI specification provides for a stylus capable of communicating with different touch sensors and touch controller integrated circuits, so that users can employ the same stylus across numerous touch-enabled devices, as long as each device’s touch controller is compliant with the USI specification.
USI founding members include Atmel Corporation; Hanvon Pentech Co., Ltd.; Intel Corporation; Lenovo Inc.; Sharp Corporation; Synaptics Inc.; Wacom Co., Ltd.; and Waltop International Corp. at the Promoter level, and Dell Global B.V.; eGalax_eMPIA Technology Inc. (EETI); Elan Microelectronics Corporation; and Focal Tech Electronics, Ltd. at the Contributor level. Membership in USI is required in order to obtain the specification and to license the IP that it contains. More information about USI and USI technology is available at www.universalstylus.org.
SUPPORTING STATEMENTS FROM USI FOUNDING MEMBERS
“As a leading provider of touch solutions, we identified a need to develop a standardized specification for an active stylus across multiple platforms,” said Stan Swearingen, SVP, CTO and GM of Touch Business Unit, Atmel Corporation. “As a founding member of Universal Stylus Initiative, we partnered with 11 other companies to define and drive a ubiquitous standard across platforms with capacitive touchscreens.

“As a company engaged in developing and promoting the use of the stylus, the most natural input for digital devices, for over 17 years, Waltop has observed the increase in stylus demand for digital devices, as well as the decrease of pen use among students. An initiative to push forward the adoption of the stylus among digital users will effectively advance its use on all mobile devices, in addition to notebook computers,” said Ben Lee, Vice President, Sales & Marketing. “Based on broad knowledge about using digital styluses developed over the years, Waltop is pleased to take part in this group in order to realize its long-lasting vision of bringing pens back to people in writing, sketching, and the numerous other occasions when grabbing a pen and a piece of paper seems so natural.”
Now that Windows 8.1 is released, the Surface Pro 2 is in the mail and other PC makers are rushing to get new machines out the door in time for the holidays, it's an excellent time to take stock of the options available for Windows artists.
The good news is that the list of tablets, convertibles and devices with active digitizers (pressure sensitive pen support) has grown dramatically since the first Surface Pro was released.
The challenge now is to keep track of all these new options and the huge variety of configurations and potential "gotchas."
I've been wanting to assemble a list like this as a companion to the "What Runs, What Doesn't" feature, but it is a huge endeavor, especially since many manufacturers don't seem to think pen support is all that important.
Fortunately for us, a couple of super users at TabletPCReview.com, JoeS and Mesosphere, have been curating just such a list since last summer. The list, which currently details 37 devices with active digitizers, is now also available as an Excel spreadsheet here.
Because it's so large, the file is awkward to print legibly. I took the liberty of reformatting it slightly and eliminated many columns in the version below. This is a great resource. I encourage you to check out the complete file and also to drop by the TabletPCReview forums and thank Joe and M. for their efforts. And of course, if you spot any errors or omissions, please let them know.
