Agenda
Design for touch
Design for Touch FirstDesign with hands and fingers in mindHit targets should be sized and spaced for touch, your finger is not a pointerDesign with comfort, ergonomics and occlusion in mind
Design for Touch FirstDesign with hands and fingers in mind
Interaction areas Reading areas
Touch Platform Goals
Unify touch mouse and pen into a single pointer input AP
Express the touch interaction language in the platform
“Code for touch, get mouse and pen for free!”
MSPointer
MSPointerDown, MSPointerUpMSPointerMoveMSPointerOver, MSPointerOut, MSPointerHoverMSPointerCancel
Basic DOM pointer events:
Derives from the same event class
Includes capture/bubble phase
Pointer events behave similarly to mouse events
Position (in the usual choice of coordinate systems)
Pointer type (touch, mouse, pen)
Contact id
Commonly used event properties:
Demo
Accelerometer
The Accelerometer
accelerometer.addEventListener("readingchanged", function(evt){ // handle change});
When the Application loads, we need to setup the accelerometer device. This is done in the app.onactivated event.
The report interval specifies in milliseconds how often the device will update the accelerometer data.
accelerometer = Windows.Devices.Sensors.Accelerometer.getDefault(); if (accelerometer !== null) { //accelerometer available on device // Establish the report interval var minimumReportInterval = accelerometer.minimumReportInterval; var reportInterval = minimumReportInterval > 16 ? minimumReportInterval : 16; accelerometer.reportInterval = reportInterval; }
Accelerometer Setup
Snapped View
Displaying Snapped View#snappedview { display:none;}
@media screen and (-ms-view-state: snapped) { #contentHost {/*hide main content*/ display:none; } #snappedview {/*show snapped view content*/ display:block; }}
var viewStates = Windows.UI.ViewManagement.ApplicationViewState; var newViewState = Windows.UI.ViewManagement.ApplicationView.value; if (newViewState === viewStates.snapped) { ... //Application is in snapped view };
Custom Logic for Snapview
User Profile data
var userInformation = Windows.System.UserProfile.UserInformation;var userPic = userInformation.getAccountPicture();
var img = new Image();var imgurl = URL.createObjectURL(userPic);img.src = imgurl;
Getting User Profile Data
Demo
Contact contract
The contact picker launches a UI that will return a single contact.
Using ContactPicker
// get reference to ContactPickervar picker = Windows.ApplicationModel.Contacts.ContactPicker();
// open the pickerpicker.pickSingleContactAsync().then(function (contact) {
// handle contact information});
Handle the result
contact.getThumbnailAsync().done(function (thumbnail) { // generate a URL for the thumbnail image thumbURL = URL.createObjectURL(thumbnail);
// use thumbURL to update the src of an image for // display face_img.src = thumbURL;});
Getting contact thumbnails
Demo
Share
People love to share
Share provides a lightweight,
in context experience for
app to app sharing
From source to target
Demo
Data package Plain text Formatted text URI HTML Images Files Custom data formats
Share sourcedataTransferManager.addEventListener("datarequested", function (e) {…// Common propertiesvar request = e.request;request.data.properties.title = "Title for data"; request.data.properties.description = "Description of the data"; request.data.properties.thumbnail = thumbnail; // of type StreamReference
// Common methods request.data.setText("Text to share");request.data.setHtml("<HTML …>");request.data.setUri(uri /* of type Uri */);request.data.setBitmap(stream /* RandomAccessStream */);
// Custom data request.data.setText("FormatID", "Text to share");request.data.setData("FormatID", datastream /* RandomAccessStream */);
Share source example// set up data transfer managervar dataTransferManager = Windows.ApplicationModel.DataTransfer.DataTransferManager.getForCurrentView();
// create event listener to be called on to fill out data packagedataTransferManager.addEventListener("datarequested", function (e) {// fill in data package with what to sharevar request = e.request;request.data.properties.title = "Title for data"; request.data.properties.description = "Description of the data"; request.data.setText("Text to share");...});
Share target example<!– extension needs to be added to package.appxmanifest --><Extensions>
<Extension Category="windows.shareTarget" StartPage="shareTarget.html">
<ShareTarget><SupportedFileTypes><FileType>.jpg</FileType>
</SupportedFileTypes><DataFormat>text</DataFormat>
</ShareTarget></Extension>
</Extensions>...// activation function in shareTarget.jsfunction activated(e) {
if (e.kind === Windows.ApplicationModel.Activation.ActivationKind.shareTarget) {
share = e.shareOperation;document.querySelector('.metadata h1').textContent = share.data.properties.title;document.querySelector('.metadata p').textContent = share.data.properties.description;
Demo
Settings
Settings contractprovides quick,
consistent, in-context access
to settings in your app
Add a settings page function scenario2AddSettingsFlyout() { WinJS.Application.onsettings = function (e) { e.detail.applicationcommands = { "helpDiv": { title: "Help",
href: "/html/2-SettingsFlyout-Help.html" } }; WinJS.UI.SettingsFlyout.populateSettings(e); };}
Demo
Live tile
Demo
var notifications = Windows.UI.Notifications;var template = notifications.TileTemplateType.tileWideSmallImageAndText02;var tileXml = notifications.TileUpdateManager.getTemplateContent(template);
var line1 = tileXml.getElementsByTagName("text")[0];
line1.appendChild(tileXml.createTextNode(“Yeti Stats"));
Live Tile
var tileNotification = new notifications.TileNotification(tileXml);
notifications.TileUpdateManager.createTileUpdaterForApplication().update(tileNotification);
Creating a Notification

Where to go from here
Combo System: Keep track of Hikers hit by each Snowball and reward the player for massive combos
Power-ups:Add other objects on the map to hit that make your Yeti stronger
Different Hikers:Hikers that have different paths or take multiple hits
Different Levels:Adding in different mountains for the Yeti to defend.
