win7 4 devs 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 3 libraries 4 multi touch 5 sensor & location 6 ribbon ux

what’s new in win7 design principles of win7

what’s new in win7

design principles of win7

taskbar » reduce complexity

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

libraries » user centric

next gen of my documents

stores a list of locations

can be leveraged by apps

multi touch » life like

nui gestures manipulations inertia

sensor & location » on the go

ribbon » not just technology

taskbar » reduce complexity

libraries » user centric

multi touch » life-like

sensor & location » on the go

ribbon » not only technology

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 a keyboard everytime) Touch is better for content consumption versus content creation!

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 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) markup style
