23. Multitouch

25. Multi-touch enabled hardware device

26. Software

27. Windows 7, .NET Framework 4.0

28. Consumers

29. New scenarios, next wave of user

31. Reading & sorting email

32. Viewing photos

33. Playing casual games

34. Consuming music and video

35. Navigating files & arranging windows

39. Decide which tier of investment is appropriate

40. Check your current applications

41. Add

42. Gesture

43. Or manipulation

44. Or inertia

46. Few Real World Usage In a sunny day, an application might increase brightness, contrast etc An application might provide location-specific information, such as nearby restaurants An application might use a human presence sensor to change the state of the Messenger status

47. Sensor Platform Overview Windows 7 features a new API for working with sensors COM-based API Works with drivers using the sensor class extension You can seamlessly interact with any type of sensor, such as Ambient light sensor Temperature gauge GPS device etc

48. Location Platform Overview The Location API lets you obtain the location without caring about the particular mechanism used to obtain the information, for example, GPS cell-tower or Wi-Fi hotspot triangulation. The Location API automatically chooses the most accurate sensor data available.

49. Sensor and Location API: Benefits Hardware-independence: No need to target vendor-specific APIs or to know hardware specifics Application sharing: Multiple applications can consume data from the same sensor simultaneously

51. Sensor Wrapper Architecture Sensor is an abstract base class with a derived type for each sensor type Derived types can add properties and events

52. Receiving Data Reports from Sensor a3dSensor.DataUpdated += OnDataUpdated; void OnDataUpdated(Sensor sensor, SensorDataReport dataReport) { Accelerometer3DReport a3dReport= (Accelerometer3DReport)dataReport; Console.WriteLine("X: {0} Y: {1} Z: {2}", a3dReport.AxisX_G, a3dReport.AxisY_G, a3dReport.AxisZ_G); }
