Windows Ribbon - Controls

Windows Ribbon API Interfaces• Consists of these main interfaces

IUIFramework – initialize ribbon, load markup resource, get or set command property values or state, set application modes

IUIApplication– user-implemented interface. Retrieves user command handler for each command defined in the markup. Notifies about view state changes

IUICommandHandler – user-implemented interface. Handles commands, updates property value (for example, setting a command to enabled or disabled based on view)

Multitouch

Multi-Touch Is Here!

• Hardware–Multi-touch enabled hardware device

• Software–Windows 7, .NET Framework 4.0

• Consumers– New scenarios, next wave of user – experience, high “WOW” factor

We’ve identified several key scenarios for multi-touch:• Navigating and consuming the

web• Reading & sorting email• Viewing photos• Playing casual games• Consuming music and video• Navigating files & arranging

windows• Using Office applications

Multi-Touch Is Scenarios

Multi-Touch Development TiersGood – Better – Best• Windows application can target one of

three levels of touch integrationGood: No specific touch APIs are used but the application UI is appropriately sized and works well with the built-in gestures

Better: The gesture APIs are supported to give smooth natural interactions

Best: Deep touch-focused experiences designed to take advantage of multi-touch features

Call To Action

• Decide the appropriate scenario that fits with concept of multi-touch feature

• Decide which tier of investment is appropriate

• Check your current applications• Add– Gesture– Or manipulation– Or inertia

• Build something amazing!

Sensors and Location

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

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

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.

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

Privacy

• Privacy: Because Microsoft recognizes that sensor and location data are private, personally identifying information, all sensors are disabled by default.

Sensor Wrapper Architecture

• Sensor is an abstract base class with a derived type for each sensor type– Derived types can add properties and

events

Receiving Data Reports from Sensora3dSensor.DataUpdated += OnDataUpdated;

void OnDataUpdated(Sensor sensor, SensorDataReportdataReport){ Accelerometer3DReport a3dReport=(Accelerometer3DReport)dataReport;Console.WriteLine("X: {0} Y: {1} Z: {2}", a3dReport.AxisX_G, a3dReport.AxisY_G, a3dReport.AxisZ_G); }
