One of the reasons that Windows took off in the first place was working more easily with devices - in those days, printers. Support for a wide range of devices is one of the reasons it's hard to other OSes to challenge Windows but Microsoft would like to get hardware manufacturers to do more with the sensor platform and DeviceStage interface it introduced in Windows 7.
With Windows 8, Microsoft wants to see "PCs use location and sensors to enhance a rich array of premium experiences. Users are not burdened with cumbersome tasks that Windows can accomplish on its own. Users are neither annoyed or disturbed by the actions the PC takes. Instead, the PC's behaviour becomes integrated into users' routine workflows. Devices connect faster and work better on Windows 8 than on any other operating system."
The 'current thinking' is for Windows 8 to include Microsoft's own Wi-Fi location service Orion (which has 50-100m accuracy in North America and Western Europe but falls back to using the location associated with IP addresses elsewhere, which can be as bad as 25km).
Orion will be used in Windows Phone 7 (as well as Hawaii, a Microsoft Research project to build cloud-enabled mobile apps which refers to Orion as a 'prototype service'). Microsoft partnered with Navizon in March to use their Wi-Fi and mobile network location database but the slides claim that Orion is buying a bigger database than Navizon's 15 million access points, giving it 40 million compared to Google's 48 million (neither matches the 120 million Skyhook gives the iPhone).
Location will be available to the browser as well as to any app that's written to use it (music players as well as mapping tools), and web apps will get access to webcams.
Microsoft is emphasising the privacy aspect of location and webcam use, with mockups of how apps can ask for location and users can choose to deny it or only allow it once. And it's also asking PC manufacturers how many devices they plan to put GPS in and offering a Device Stage interface for using a PND like a Garmin nuvi as a GPS source for your PC.
LOCATION PRIVACY:
Web apps can see your location and use your webcam – but you get to control that to protect your privacy
As we've said before, Device Stage will become the standard way you work with devices; Microsoft previewed the options you'll get with a featurephone and a webcam as well as GPS.
Along with GPS, Microsoft is expecting PCs to include infrared sensors as well as the ambient light sensors that are becoming common, and the accelerometers that are in tablets with rotating screens.
Put that together and the PC could know which way up it is, whether there's anyone in front of it - or near it and what the lighting is like in the room. So when you walk into the room your PC notices and wakes itself up so by the time you sit down the webcam is ready to recognise you - and no waiting or having to line your face up with a box on screen.
If this works, the camera will pick your face out of the room, like Photo Gallery finding a face in a picture (hopefully without thinking the face in a picture on the wall is you). When you walk away it goes back to sleep again.
We like the idea of rotation lock buttons on 'Lap PCs' so you can move them around to control a game without flipping he screen repeatedly; again, if you look away from the game, Microsoft envisages it pausing automatically and if you pass a slate to someone it will switch to their account automatically.
What's in: USB 3, Bluetooth hands free and headset profiles (mono and stereo audio).
What's out: Microsoft has no plans to support Bluetooth 3.0 + High Speed, 1394 might be deprecated and Microsoft seems to expect USB 2 ports to be phased out in favour of USB 3 within the lifetime of Windows 8.
What's under consideration: Bluetooth Low Energy (from Bluetooth 4.0). What's not mentioned: Intel LightPeak, although Microsoft does ask if it's missing anything on its list of connectivity.
