Hardware Foundation Updates
Capacitive touch 4 or more contact points
Sensors A-GPS, Accelerometer, Compass, Light, Proximity,
Camera 5 mega pixels or more
Multimedia Common detailed specs, Codec acceleration
Memory 256MB RAM or more, 8GB Flash or more
GPU DirectX 9 acceleration
CPU Qualcomm MSM8x55 800Mhz or higher
Hardware buttons | Back, Start, Search

Improved capability detection APIs
Measures resultant acceleration (force) on device
Pros:
Available on all devices
Cons:
Difficult to tell apart small orientation changes from small device motions

Gyroscope
11
Gyroscope API
Virtual sensor, combines gyro + compass +
accelerometer
Motion Sensor vs. gyro or compass or
accelerometer
More accurate
Faster response times
Comparatively low drift
Can disambiguate motion types
Has fall-back if gyro is not available

2
Motion Sensor
Always prefer Motion Sensor when available
Motion API
if (Motion.IsSupported) { _sensor = new Motion(); _sensor.CurrentValueChanged += new EventHandler<SensorReadingEventArgs<MotionReading>> (sensor_CurrentValueChanged); _sensor.Start(); } void _sensor_CurrentValueChanged(object sender, SensorReadingEventArgs<MotionReading> e) { Simple3DVector rawAcceleration = new Simple3DVector( e.SensorReading.Gravity.Acceleration.X, e.SensorReading.Gravity.Acceleration.Y, e.SensorReading.Gravity.Acceleration.Z); … }
Degraded modes have lower quality approximations
When Motion.IsSupported is false, apps should use accelerometer or other input and control mechanisms

Motion Sensor Adapts to Devices
Accelerometer Compass Gyro Motion
Yes Yes Yes Full
Yes Yes No Degraded
Yes No Yes Unsupported
Yes No No Unsupported
Sensor Calibration
Calibration Event is fired when calibration is
needed
Both Compass and Motion sensors need user
calibration
Apps should handle it
Provide UI asking user to move device through a full
range of orientations
Not handling will cause inaccurate readings
We are considering providing copy & paste solution

Database APIs: Datacontext and attributes // Define the data context.
public partial class WineDataContext : DataContext
{
public Table<Wine> Wines;
public Table<Vineyard> Vineyards;
public WineDataContext(string connection) : base(connection) { }
}
// Define the tables in the database
[Table]
public class Wine
{
[Column(IsPrimaryKey=true]
public string WineID { get; set; }
[Column]
public string Name { get; set; }
……
}
// Create the database form data context, using a connection string
DataContext db = new WineDataContext("isostore:/wineDB.sdf");
if (!db.DatabaseExists()) db.CreateDatabase();
Queries: Examples // Find all wines currently at home, ordered by date acquired var q = from w in db.Wines where w.Varietal.Name == “Shiraz” && w.IsAtHome == true orderby w.DateAcquired select w; Wine newWine = new Wine {
WineID = “1768", Name = “Windows Phone Syrah", Description = “Bold and spicy"
}; db.Wines.InsertOnSubmit(newWine); db.SubmitChanges();
