Key Concepts
Two Sides of the Same Coin
Adaptive rendering
Mobile controls and device adapters generate
an appropriate rendering for each device
automatically
Customisation
Programmatic model to customise the
rendering for a particular device.
Why?
Building Mobile Web Applications
The Adaptive Rendering Process
1. HTTP
request
Discover device
capabilities
2. ASP.NET
processing
• Height and width
• Color
• Images
• Phone call ability
Render ASPX page
• Process page
• Each control builds
its own layout
Returned as proper
browser protocol
4. Adaptive
response
• HTML
• cHTML
• WML
• XHTML
3. ASP.NET result
A Brief Aside…
Cookieless Sessions
Session State no longer requires client cookie
support for SessionID
Can optionally track SessionID in URL
Requires no code changes to the application
All relative links continue to work
Cookieless Sessions
How To…
1.
2.
Create/Edit “web.config” file in the vroot
Add following text:
<configuration>
<system.web>
<sessionState cookieless=“true”/>
</system.web>
</configuration>

Customising for Particular Devices
Why?
Optimise the generated rendering
Per device or class of device
Used on a per application basis
Comparison- or Evaluator-based filters
Control the exact display
Ability to override default behavior
Device-Specific Customisation
Property Overrides
Change the property value of a control only
on certain devices
Example: Set the Text property of a Label control
to a long string on large screen devices, and to a
short string on small screen devices
Device-Specific Customisation
Using Property Overrides
In persistence format
<mobile:Label id="Label2" Runat="server" Font-Bold="True">
<DeviceSpecific>
<Choice Filter="isPocketIE"
Text="...Breaking News - Breaking News...">
</Choice>
<Choice Text="News Just In! "></Choice>
</DeviceSpecific>
</mobile:Label>
In code
MobileCapabilities cap =
(MobileCapabilities)Request.Browser;
if (cap.HasCapability(“isPocketIE“, null))
{
Label2.Text = "...Breaking News - Breaking News...“;
}
Else Label2.Text = "News Just In! ";
Defining Device Filters
All customisation with Property Overrides and
Templates relies on device filters
Visual Studio .NET creates a default set of
device filters in Web.config
<deviceFilters>
<filter name="isHTML32" compare="PreferredRenderingType"
argument="html32" />
<filter name="isWML11" compare="PreferredRenderingType"
argument="wml11" />
<filter name="isPocketIE" compare="Browser"
argument="Pocket IE" />
<filter name="prefersGIF" compare="PreferredImageMIME"
argument="image/gif" />
<filter name="prefersWBMP" compare="PreferredImageMIME"
argument="image/vnd.wap.wbmp" />
...
</deviceFilters>

DataBinder.Eval(((ObjectListItem)Container).DataItem, “FirstName”)
Using XML Web Services and the
Object List
XHTML Browsers And CSS
Cascading Style Sheets (CSS)
The best way to define presentation
Separates presentation from content
W3C recommendation (CSS1)
Supported by major desktop browsers
CSS is also supported by the latest mobile devices
Pocket Internet Explorer on SmartPhone 2003 supports HTML 4.01,
XHTML-Basic, and CSS1
WAP 2.0 devices support XHTML-MP and Wireless CSS
(Nokia Series 60, Sony-Ericsson Smartphones)
ASP.NET Mobile Controls Runtime
Supports XHTML browsers in Device Update 2 and later
Generates CSS style sheet dynamically from standard mobile
style properties
Programming CSS Stylesheets
Create a style sheet in your
project
.Subhead
{
font-weight: bold;
font-size: smaller;
color: orangered;
}
Add CSSLocation attribute to <mobile:Form> tag
pointing at stylesheet
<mobile:Form id="Form1" runat="server"
csslocation="stylesheet1.css“ … >
Set allowCustomAttributes=“true” in web.config
<system.web>
<mobileControls allowCustomAttributes="true“ />
</system.web>
Programming CSS Stylesheets
Use CssClass attribute to apply a style class
in the style sheet to a control
<mobile:label id="Label1" runat=“server”
cssclass=“Subhead" >
This label uses the style from the CSS!
</mobile:label>
Other attributes
CssCommandClass: Use with ObjectList to style
the command link
CssLabelClass: Use with ObjectList to style the
label fields
CssPagerClass: Use with Form to style
pagination prompts
Using CSS
Speech On The Mobile Web?
Why Bother?
Hands-free
Eyes-free
When speech is faster or easier
For what?
Data Entry
Query the user verbally
Get input verbally
Command and control
Say what you want rather than clicking through menus
Searching through data
Ever tried sifting through 3,000 rows with a stylus?
Notifications
SALT And ‘Speech Tags’
Speech Application Language Tags
Extends HTML, XHTML etc.
Enables multimodal (speech + GUI) and telephony
applications
Object and event model, script for dialog
management
Standard being driven by SALT Forum
Founded 10.1.01: Cisco, Comverse, Intel,
Microsoft, Philips, Speechworks
Speech Tags Overview
<prompt >
configures speech synthesizer and
plays out recorded prompts
<reco >
configures and executes speech
recognizer, handles events
<grammar > specifies recognition resources
<bind >
binds recognition results to page
<dtmf >
specifies telephone keypad input
Call Control object
executes call transfer, conference, etc.
handles events (answer, hangup etc.)

SALT (Speech Application Language Tags)
Deploy your speech apps as Web sites
Use your existing ASP.NET, HTML, and PIE
skills to build speech apps
Speech Recognition
Grammar
Defines what to listen for
Usually associated with a particular task
A set of syntactic rules for assembling groups of
words
Expressed with SRGS
(W3C Speech Recognition Grammar
Specification)
Can be statically authored or dynamically
generated
Speech Recognition
Results
Raw text
“Arriving at Heathrow”
Semantic
Uses your grammar to attach semantic meaning
They specified their destination
It is an airport
It is “LHR”
Expressed with SML (Semantic Markup Language)
Includes confidence scores
Text To Speech
Raw text
SSML (Speech Synthesis Markup Language)
for emphasis and “say as” hints
Prompt database
Combine synthesized and pre-recorded speech
Recorded: “Turn left at”
Synthesized: “Smith Street”
App just provides: “Turn left at Smith Street”
Speech Application SDK
Built for the .NET platform
Integrated with Visual Studio .NET
Speech Controls for dialog authoring
Controls built on the ASP.NET control architecture
Abstracts low-level Speech Application Language Tags
Grammar authoring
Build and edit grammars with graphical representation
Associate recognised terms with semantic interpretation
Prompt management
Prompt Editor for scripting, recording, and tagging prompts
Testing and debugging
Speech debugging console for tracing through a dialog
Telephony Application Simulator for simulating phone-based dialogs
Speech Input to a Web Page
