  1. HW-664C Chalk talk for sensor and location support in Windows Fred Bhesania – Program Manager LeadSandy Spinrad - Test Lead Dino Natucci – Program Manager Gavin Gear – Program Manager Microsoft Corporation

  2. Agenda • Sensors and location opportunities • Overview of sensor and location platform • Demo • Hardware/software validation You’ll leave with examples of how to • Understand location/sensor architecture and inbox driver story • Gain knowledge of critical validation tools and experiences to optimize your platforms

  3. Opportunities for sensor and location apps • Make user experiences more relevant to the user’s location • Enhance apps by adapting to the surrounding environment • Every app can use simple sensor gestures • Easily create casual games and apps that use sensors • Use sensor fusion to implement cutting edge apps

  4. Sensor scenarios • Sensor categories • Light sensor • Fused motion sensors • Presence sensor • Sensor scenarios • Basic – rotate, flip, shake • Intermediate – raw sensors • Advanced – sensor fusion Accelerometer Sensor Gyroscope Sensor

  5. Location scenarios • Location • Search points of interest (POI) • Geo-tag photos and other content • Navigation • Location aware notifications • weather, news , sports, coupons • Many others…

  6. Platform overview Blue = In Windows 8 Green = 3rd Party Black = Firmware Metro style app Sensor Service Win32 app WinRT Sensor API Sensor API (Win32) UMDF Sensor Class Extension Sensor Driver (3rd Party) Sensor Driver (HID) Sensor Hardware (non-HID) Sensor Hardware (HID)

  7. Windows 8 inbox sensor drivers • HID sensor class driver • Buses supported = USB, I2C • Sensors supported = light, motion, presence • Built on industry standard – USB-IF • ACPI ALS sensor driver • Buses supported = ACPI methods • Sensors supported = light • Built on industry standard – ACPI 4.0

  8. Sensor hardware • For Slate PC and Convertible PC hardware • Light sensor • Motion sensors + fusion • Accelerometer • Magnetometer • Gyroscope • GPS (on systems with mobile broadband hardware)

  9. Hardware and software validation

  10. Hardware/software validation • Review certification requirements • Certification tests primarily validate • Required sensors are present • Sensors are correctly orientated • Sensors provide the required data fields • OEMs and IHVs should develop extensive test plans to thoroughly exercise their sensors under a variety of conditions • Power management, plug and play, noisy RF conditions, system stress, darkness, etc. • Use the common device verification tools (WDF verifier, driver verifier, etc).

  11. demo Sensor diagnostic tool Visualizing sensor data

  12. Hardware integration and lessons learned • Sensors • ALS placement • Magnetic interference • Calibration • GPS • Antenna selection and placement • RF interference • OEMs and IHVs need to work closely together for system design & integration

  13. Related sessions • [HW-249T] Architecting and integrating sensor drivers • [PLAT-781T] Using location & sensors in your app • [HW-260T] Windows Certification: improvements to the logo program
