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
![Page 12: 2 Win7 For Devs Ux Touch Sensors](https://reader038.fdocuments.in/reader038/viewer/2022102815/5554b864b4c90559398b491f/html5/thumbnails/12.jpg)
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
![Page 13: 2 Win7 For Devs Ux Touch Sensors](https://reader038.fdocuments.in/reader038/viewer/2022102815/5554b864b4c90559398b491f/html5/thumbnails/13.jpg)
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
![Page 14: 2 Win7 For Devs Ux Touch Sensors](https://reader038.fdocuments.in/reader038/viewer/2022102815/5554b864b4c90559398b491f/html5/thumbnails/14.jpg)
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

Live Thumbnails
Live thumbnails: A live previewWindows Vista: One thumbnail per windowWindows 7: Grouped thumbnails
![Page 17: 2 Win7 For Devs Ux Touch Sensors](https://reader038.fdocuments.in/reader038/viewer/2022102815/5554b864b4c90559398b491f/html5/thumbnails/17.jpg)
Windows 7 Taskbar – Thumbnails
Remote-control for a windowSurface key commandsAccessible from taskbar thumbnail Up to seven buttons
![Page 18: 2 Win7 For Devs Ux Touch Sensors](https://reader038.fdocuments.in/reader038/viewer/2022102815/5554b864b4c90559398b491f/html5/thumbnails/18.jpg)
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
![Page 19: 2 Win7 For Devs Ux Touch Sensors](https://reader038.fdocuments.in/reader038/viewer/2022102815/5554b864b4c90559398b491f/html5/thumbnails/19.jpg)
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

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
![Page 29: 2 Win7 For Devs Ux Touch Sensors](https://reader038.fdocuments.in/reader038/viewer/2022102815/5554b864b4c90559398b491f/html5/thumbnails/29.jpg)
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.
![Page 30: 2 Win7 For Devs Ux Touch Sensors](https://reader038.fdocuments.in/reader038/viewer/2022102815/5554b864b4c90559398b491f/html5/thumbnails/30.jpg)
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

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

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

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.
