spirit of this presentation

what’s new in win7?

what’s in it for devs?

where do we get the resources?

spirit of this presentation

not only about technology

conversational

work in progress….

what’s new in win7

1 design principles of win7

2 taskbar

design principles of win7

taskbar » reduce complexity

single tool to: launch, switch & manage apps + their tasks

what’s new in win7

design principles of win7

libraries » user centric

-next gen of my documents

-stores a list of locations

-can be leveraged by apps

what’s in it for devs

multi touch

sensor & location

ribbon

multi touch

Scenarios good for touch: maps & pics

Touch & gestures that make up the NUI

Will be present in small form factors (phones) to large ff (surface units)

Touch scenarios – factory floors to phones (can’t pull out akeyboard everytime)

Touch is better for content consumption versus content creation!

multi touch & WPF

multi touch & WPF

multi touch & WPF

Certain multi-gesture manipulations with inertia will be available in WPF 4

multi touch & WPF

Good - Out of the box experience for legacy apps is available in Win7

multi touch & gestures

Gestures: 1 or 2 fingers inputs that translate into action

OS does listening for gestures

You can program the app to listen for WM_GESTURE messages or notifications

multi touch & gestures

Good - Out of the box experience for legacy apps is available in Win7

some gestures keywords

GetGesture

SetGestureConfig api can be set to turn on or turn off gestures

You can slow down, add inertia etc

WM_GestureNotify

GetGestureInfo

Usually gesture messages should be limited to 30 gestures per second

GID_Rotate

understanding wm_gesture

WM_Touch

Similar to mouse position giving multiple (an array of) XY co-ords

manipulations

Manipulations are the superset to gestures.

Manipulations allow you to simultaneously do multiple gesture paired up with inertia and other physics engine transforms.

So, you can rotate, move and zoom in concurrently.

Needs raw data and depends on how much the hardware can support. The most complex form of Multi-touch!!

manipulations

Inertia & physics engines

sensor & location

sensor & location

sensor & location

native sensor sdk with win7

can be connected to sensing devices like gps, temp sensor, light sensor, accelerometers etc

os level resource: multiple applications can use the output of the sensor simultaneously without having resource constraints

sensor & location

iSensorManager: com interface that manages all the sensors in the system

GetSensorByID used to query a sensor by ID

GetSensorByCategory used to query a sensor if environmental sensor, physics sensor

Onsensor: event tells you new sensor

Isensor you can get data about sensor

ribbon

native ribbon

win32 com based

managed code as well

(vb, C# and XAML)
