2 40 years ago This was the state of the art

3 and this was the smartest part in a car

4 Today Sensors enable practical magic

5 Sensors in modern PCs Ambient Light Location/GPS Accelerometer Proximity Temperature

6 PC Penetration 60% 50% 40% 30% 20% 10% 0% Image Sensor Penetration Mobile PC Source: Gartner % 40.0% 30.0% 20.0% 10.0% 0.0% GPS Sensor Penetration (WWAN/WiMax), Mobile PC Source: IDC % Accelerometer Penetration, Mobile PC Source: ABI Research % 45.0% 40.0% 35.0%

7 Location Data is all around us GPS WiFi Triangulation Cell Tower Triangulation IP Georesolution

8 But it s fragmented Where do you get it? Which technologies? Licensing terms Install base Why is it so complicated? Exclusive access to COM ports Different APIs for different technologies No access control or auditing

9

10 Windows 7 Makes it Easy

11 Standard way to get location data Standard way for applications access location data The same app will work on any Win7 machine with physical or logical drivers More then one application will work at the same time

12 Privacy user is always in control

13 HTML5 Geolocation API Javascript API to enable location-aware web-apps Microsoft is observing and contributing to the W3C Geolocation API standardization process Privacy control is absolutely vital for webapps Unify the permission opt-in experience Protect user privacy Provide clearer, simpler UI

14

15 Key end-to-end Scenarios Consumer: Local content (advertising, news, weather, gadgets, etc) Navigation Geotagging and search Social presence / Social Networking Enterprise Document geofencing Location based machine policies Enterprise location services (asset tracking and recovery) Calendar integration (next appointment routing, auto time zone switching)

16 Sensor Integration: GPS Checklist Select a location provider(s): WWAN+GPS or standalone GPS chip Virtual driver (IP, WiFi, Cell Tower) Use multiple providers to increase availability Consider GPS antenna placement Ensure supplier provides Windows 7 driver Starter edition only has Default location support * See: for more information

17 Location drivers (in-progress) Ericsson F3507g and F3607gw Qualcomm Gobi2 Skyhook Wireless XPS: Hybrid WiFi positioning system We are working with other major WWAN and standalone GPS vendors to get Win7 support as well If your supplier is not listed talk to them!

18 Platform integration GPS WiFi Resolution Cell Tower Resolution IP Georesolution Accuracy* 3 m 30 m 50 m-150 m 100 m tens Km Hardware requirements GPS chip or 3G card Existing WiFi card 3G card Depends on the provider None Driver Requirement Works with existing hardware Hardware Integration Driver from IHV (or need to write one) No, must have GPS chip Virtual Driver (from Location Provider ISV) Virtual Driver (from Location Provider ISV) Yes Yes Yes Yes No No No * Gartner, Location Technologies 2008 Virtual Driver (from Location Provider ISV)

19 Tools Sensor Diagnostic Tool Shows Sensors, Properties, Data, Events Event Logging Shows current location API status Enhanced Default Location Set the location reported by the Location API Reverse geocoding

23 ALS: Various view modes Indoor mode Night mode Outdoor mode

24 Light-Aware Applications - photos Photos taken in direct sunlight (100K lux) Normal photo Optimized photo

25 Key end-to-end scenarios Adaptive Brightness Natively supported by Windows 7 Light aware video/dvd playback Light aware image viewers Light aware reader application Automatically changed layout Night mode, Day mode auto switching

26 ALS Hardware Integration ALS Sensor Placement ALS Sensor Checklist Select a suitable light sensor part Select optimized placement for the light sensor(s) Premium machines may have multiple sensors Use ACPI 3.0b compliant BIOS firmware that will expose the ALS hardware (or write UMDF driver) No ALS support in Windows Starter * See: for more information

27 ALS parts currently available (examples) Capella Microsystems CM3212/CM3213 digital ALS IR/UV rejection 0-50K lux dynamic range Intersil ISL29013 digital ALS IR/UV rejection 128K lux upper range TAOS TSL2560 series digital ALS IR/UV rejection K lux Multiple ALS per channel

31 Logo Requirements And Tests Requirements are listed under Input 048: Applies to all sensors Input 049: Applies to location sensors only Input 050: Applies only to ambient light sensors Requirements are focused around Exposing proper data fields Exposing properties correctly Submit as Input > Sensor device Run sensor tests before other tests Must remember to enable access to sensor before running tests, else they will fail

32 Using Managed Code using Windows7.Location; LatLongLocationReport myreport; LatLongLocationProvider myprovider = new LatLongLocationProvider(1000); myreport = (LatLongLocationReport)myProvider.GetReport(); Console.WriteLine("Lat: {0} Long: {1}\n", myreport.latitude.tostring("f2"), myreport.longitude.tostring("f2")); Sample.NET interop layer: ProjectReleases.aspx?ProjectName=Senso rsandlocation&releaseid=2359
