THE 1.0 SPECIFICATION FEATURES A ROBUST TWO-WAY PROTOCOL DESIGNED FROM THE GROUND UP TO SUPPORT A RICH SET OF BASE FEATURES INCLUDING MULTIPLE, SIMULTANEOUS STYLUSES AS WELL AS EXTENSIBILITY FOR PER-VENDOR CUSTOMIZATION AND FUTURE USAGES.USERS WILL BE ABLE TO USE A SINGLE USI STYLUS ACROSS ALL OF THEIR USI-ENABLED DEVICES AND ANY USI STYLUS SHIPPED WITH DEVICES WILL WORK WITH OTHER USI-ENABLED DEVICES, EVEN THOSE FROM DIFFERENT MANUFACTURERS. ADDITIONALLY, THE USI 1.0 SPECIFICATION ALSO PROVIDES THE CAPABILITY TO USE MULTIPLE STYLUSES FROM DIFFERENT MANUFACTURERS ON A SINGLE DEVICE. THIS IS A BREAKTHROUGH CAPABILITY AND INDUSTRY-FIRST ENABLED BY THE USI 1.0 SPECIFICATION.AN ADDITIONAL BENEFIT OF THE USI STANDARD IS THE ABILITY TO DELIVER A CONSISTENT STYLUS USER EXPERIENCE ACROSS PLATFORMS. THIS CONSISTENCY AND EASE-OF-USE, COUPLED WITH INTEROPERABILITY, INCREASES THE CONSUMER APPEAL OF AN ACTIVE STYLUS AND WILL HELP PROLIFERATE THE TECHNOLOGY.USI HAS ISSUED AN ERRATA IN CONJUNCTION WITH THE SPECIFICATION TO AMEND, EDIT AND DEFINE THE SPECIFICATION DETAILS.
