Windows Ribbon API Interfaces<br /><ul><li>Consists of these main interfaces</li></ul>IUIFramework – initialize ribbon, load markup resource, get or set command property values or state, set application modes<br />IUIApplication– user-implemented interface. Retrieves user command handler for each command defined in the markup. Notifies about view state changes<br />IUICommandHandler – user-implemented interface. Handles commands, updates property value (for example, setting a command to enabled or disabled based on view)<br />

experience, high “WOW” factor</li></li></ul><li>Multi-Touch Is Scenarios<br />We’ve identified several key scenarios for multi-touch:<br /><ul><li>Navigating and consuming the web

31.
Reading & sorting email

32.
Viewing photos

33.
Playing casual games

34.
Consuming music and video

35.
Navigating files & arranging windows

36.
Using Office applications</li></li></ul><li>Multi-Touch Development TiersGood – Better – Best<br />Windows application can target one of three levels of touch integration<br />Good: No specific touch APIs are used but the application UI is appropriately sized and works well with the built-in gestures<br />Better: The gesture APIs are supported to give smooth natural interactions<br />Best: Deep touch-focused experiences designed to take advantage of multi-touch features<br />

37.

38.
Call To Action<br /><ul><li>Decide the appropriate scenario that fits with concept of multi-touch feature

39.
Decide which tier of investment is appropriate

40.
Check your current applications

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

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

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

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

50.
Privacy<br /><ul><li>Privacy: Because Microsoft recognizes that sensor and location data are private, personally identifying information, all sensors are disabled by default.</li></li></ul><li>Sensor and Location Platform Architecture – The Big Picture<br />Gadget or script<br />Application<br />Application<br />Location API<br />Location IDispatch Interface<br />Sensor API<br />Location and Other Sensors Control Panel<br />User<br />System<br />Sensor class extension<br />Sensor class extension<br />UMDF sensor driver<br />UMDF sensor driver<br />Logical location sensor<br />(Triangulation)<br />Sensor<br />device<br />

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