All of Microsoft’s products

Windows 7 Taskbar – Icons

Face of your programLarge and small iconsOnly customer can pinColor hot-track

Icon OverlaySurface important notificationsAppears over your program’s icon

Progress barSurface important notificationsAppears in your taskbar button

IconsBest practices

Are you putting your best foot forward?Make sure your icon looks greatCheck different DPIsCheck different glass colors and disabled glass

How does Color Hot-track look?Determined by your icon’s dominant color

Get More From Taskbar ButtonsOverlay and progress icons

Consolidate: Uncluttered notification areaProvide progress and additional information through the taskbar button

It’s free if you use standard progress dialogs

Taskbar Overlay and ProgressDesign considerations

Notification area is now user controlled:Leave yourself out if possible!

Use taskbar buttons for custom progress or status information

Peek Preview (Aero Peek)

Live peek without a click

Live Thumbnails

Live thumbnails: A live previewWindows Vista: One thumbnail per windowWindows 7: Grouped thumbnails

Windows 7 Taskbar – Thumbnails

Remote-control for a windowSurface key commandsAccessible from taskbar thumbnail Up to seven buttons

Thumbnail ToolbarsContrasting Thumbnail Toolbar commands and user tasks

Thumbnail Toolbar Commands

Jump List User Tasks

Surface common window commands (e.g. menu items, window toolbar commands)

Define entry points intothe application

Specific to the window they’re assigned to Application-wide in scope

One set of thumbnail toolbar commands per window

One set of user tasks per application identity

Windows commands can be dynamic List of user tasks must be static

Exposing Custom ThumbnailsOverriding Automatic Thumbnail Preview

To provide a custom thumbnail preview representation for a window:

Set the DWM window attribute to say you will provide an “iconic bitmap” for the windowRespond to the window messages DWM will then send in order to set the preview – done for both thumbnail- and full-sized previews

Hi phone!

Windows 7 Taskbar – Custom Switchers

Surface custom UI (e.g. TDI/MDI)Custom thumbnails for each windowAppears in your program’s window list

MDI and TDI Window Switchers

What about Internet Explorer tabs?

Windows API Code Pack for the .NET Library

Managed class library to access to Win 7 features

Windows Shell namespace Windows Vista and Windows 7 Task Dialogs. Support for Shell property system. Taskbar Jumplists, Icon Overlay and Progress bar. Common file dialogsSupport for Direct3D 11.0 and DXGI 1.0/1.1 APIs. Sensor Platform APIs Extended Linguistic Services APIs

Windows 7 Taskbar – Jump Lists

Mini Start Menu for your programSurface key destinations and tasksCustomizableAccessible via right-click and via dragAPIs use the name “Destination List”

Destinations(“nouns”)

Tasks(“verbs”)

Known categories

Custom categories

User Tasks

Taskbar Tasks

Pinned category

Windows 7 Taskbar – Jump Lists

Customizing the Jump ListStep 1: Get the free stuff to work

Associate your program with the file extensionUse common file dialogsUse explicit recent document API

Customizing the Jump ListStep 2: Adding tasks

What would your user like to do?Launch your application with special arguments?Launch other applications?

Tasks are IShellLink objectsRich shortcut semantics including arguments, working directory, icon, and so on.

Customizing the Jump ListStep 3: Do you have categories?

Does it make sense to categorize documents?Is frequent, recent, pinned not enough?For example, Inbox, Outbox, Sales, Marketing …

Categories contain IShellItem or IShellLink objects

These are documents: You need a file association

Windows Ribbon - Roadmap

Sensor & Location APINew

Location devices exposed as virtual COM portsExclusive application accessNot secureProprietary data formats (NMEA, others)

GPS doesn’t work indoorsHard to support multiple technologies at once

Sensors are integrated as vertical solutionsApplications need to know sensorhardware specificsLimited adoption and scope

Limitations Of Sensors Today

Sensor And Location Platform

Provides unified driver model for all types of sensor devices

Physical sensors (e.g., GPS devices, Light Sensors)Logical sensor (e.g., Wi-Fi triangulation resolver)

Provides standard APIs for accessing sensorsSensor API: C++/COM / Managed code (Windows Bridge)

Raw access to any sensor

Location API: C++/COM, Idispatch Managed code (Windows 7 API Code Pack)

Abstracted API for location data

Puts user in control of information disclosure

What Info Do Sensors Use?Enumerated via category and type

Category represents what is being sensedType represents how it is sensed

Properties (read-only or read-write)Data (property keys for units, data field…)Events (data-driven)State

Location Platform Benefits

Single API call to answer “Where am I?”Independent of provider used todetermine locationSynchronous and Asynchronous modelsScript/automation compatible

Automatic transition between providersMost accurate providers have priority

Concurrent access for multiple applicationsDefault Location

Provided by user as fallback when no other sources are available

Light-Aware Applications

UI without light-awareness,40% screen brightness

UI with light-awareness,100% screen brightness

Photos taken in direct sunlight

Ambient Light SensorsMeasure light intensity (i.e., illuminance) in LUX (lumens/square meter)Includes class driver support for ACPI light sensors

Working with OEMs to integrate light sensors into notebook designs

Adaptive brightness feature supportedOS automatically adjusts display backlight

Light-aware applications can use these sensors to optimize UI content for various lighting conditions

How To Build Light-Aware UIScale

Change font size/zoom level‘Weight’ of lines

ContrastColor

SaturationComplementary vs Adjacent

Smooth transitions between changes are extremely important for overall user experience

Multi Touch Is HereMT = two or more independently traceable touch pointsConsumers & MT

scored very favorably in user testingoffers clear differentiation with a high “WOW” factor for consumersenhances on-the-go use & enables new scenarios

HardwareMulti-touch capable machines in market today in a broad set of form factors

Navigating and consuming the webReading & sorting emailViewing photosPlaying casual gamesConsuming music and videoNavigating files & arranging windowsUsing Office applicationsAll focused on consumption

That led to four areas of investment:Developer Platform: At the root is the touch developer platform that exposes touch APIs for any application UI Enhancements: Focusing on the core scenarios, many parts of the core UI have been optimized for touch experiences. Gestures: Multi-touch gestures have been added to enable consistent panning and zooming in most applications.Applications: A set of multi-touch focused applications that demonstrate the power of touch. These will ship separate from Win7.

Multi Touch Scenarios

Control Panel – Pen and Touch

Gestures and Developers Platform

Consistent Multi-touch gesturesGestures for double click, right click, single & two finger panning, two finger zoom, and two finger rotation are built into the Windows 7 platform.These gestures are available across the OS and available “for free” to most applications.

Multi-touch platformDelivered first for Win32 and COMIntegrated into next version of WPF 4.0 shipping post Windows 7Touch enabled vs. Touch optimized applications

Feature supportGesture notifications: WM_GESTUREInertia and feedback algorithms Raw data support: WM_TOUCH or RTS“Surface-style” API providing 2D manipulation and inertia support
