How to design multi-touch hardware solutions for Windows 8 and Windows 8.1
Updated: September 4, 2013
This topic describes how to design hardware solutions for Windows Touch. It provides guidelines for independent hardware vendors (IHVs) and original equipment manufacturers (OEMs) to address the quality standards that these hardware solutions must meet so that users have a successful experience with multi-touch.
This information applies to Windows® 8 and Windows 8.1.
Development cycle
Windows Hardware Certification Requirements describes the base quality that is expected of Windows Touch devices. These are the guidelines for OEMs and IHVs who design multi-touch devices.
Throughout the product cycle, we recommend that you use the Windows Hardware Certification Kit to verify your implementation. The Windows® Hardware Certification Kit (Windows HCK) is not just for certification, but is also helpful for testing your design and implementation.
We also recommend testing and verification with real users outside the lab at major development milestones. Lessons from real-world usability testing are often invaluable.
