MS unveils Win8 logo requirements. Win8 logo devices to include lots of interesting and useful features
In his most recent monthly column for WindowsITPro entitled “The Rigor of Windows 8 Hardware Certification Requirements, …” Windowsmeister Paul Thurrott provides a snapshot of the current requirements that Microsoft intends to levy on those seeking to put the Windows 8 logo decal on their PCs, notebooks, tablets, and smartphones. It’s an interesting and detailed collection of info, based in turn on Rafael Rivera’s equally interesting WithinWindows blog entitled “Windows 8 Secrets: PC and Device Requirements.” Both are worth reading in their entirety; here I’ll summarize some of the most interesting high points.
- 5-point digitizers: Windows 8 touch PCs must support at least 5 touch points (five fingers’ worth, guaranteeing support for complex multi-touch swipes and gestures).
- NFC “touch marks”: Near field communications lets devices interact with each other when they’re so close as to be nearly touching, and are key to emerging technologies for payment transfers especially from smartphones to cash registers (or computers acting like same).
- 5 required hardware buttons: devices must provide buttons for power, rotation lock, the Windows key, and volume up/down controls. Also, devices that belong to a domain that lack keyboards must support Windows Key + Power as an alternative to the Ctrl+Alt+Del key sequence (the infamous “three-fingered salute” for those who remember DOS and early Windows versions).
- Minimum component requirements include 10 GB of free storage space after Win8 is installed, support for UEFI (see my 9/23/2011 blog for more info), WLAN, Bluetooth and LE networking, Direct3D 10 graphics with a WDDM 1.2 driver, 1366×768 screen resolution or better, 720p camera, an ambient light sensor, a magnetometer and an accelerometer, a gyroscope, at least one USB 2.0 controller and exposed port (or better), and audio speakers. Sounds like a decent smartphone or tablet, eh?
- Graphic drivers must be upgradeable without requiring a reboot (easier to do thanks to dropping XDDM drivers and keeping only WDDM drivers for Windows 8).
- 2-second resume(does not apply to ARM-based devices yet) from Standby (S3) to “resume complete” status. Rivera speculates “Microsoft simply doesn’t have enough data in this space” to impose the same restriction on ARM as on x86; Thurrott speculates that “it will be added in a future release, such as Windows 9.”
Veeeeeeeeeeeeeeery interesting. Be sure to check out the original posts, too!
