Session II Agenda

• Sensors and Location• Web Services

• Azure• Rest• Odata

• Data binding / Sample Data• Isolated Storage• Data Roaming

Sensors and Location

Know your surroundings

Opportunities for sensor and location apps

• Make user experiences more relevant to the user’s location

• Enhance apps by adapting to the surrounding environment

• Every app can use simple sensor gestures• Easily create casual games and apps that use

sensors• Use sensor fusion to implement cutting edge apps

Sensor Fusion inputs and outputs (9-Axis)

Demo

NO DEMO Unless you have a sensor enabled laptop.Using Location in your application

LocationWhere am I??

Location scenarios

• Location• Search points of interest (POI)• Geo-tag photos and other content• Navigation• Location aware notifications

• weather, news , sports, coupons

• Many others…

Declare the need for Geolocation

Location-based user experience

Great apps deliver a continuous experience for your

customers as they switch between apps and PCs

Many ways to enable a continuous experience on one PC

Continuity across many PCs: today

• Register a domain• Setup your services and infrastructure• Figure out security and user management• Build sync infrastructure• Scale your service for millions of users

Local Cache

One PC vs. many PCs

Local

Large caches for offline use

Offline storage for HTML5 based apps

Temporary data and device specific configuration data

Roaming

Small, key-value pairs for app settings

User context like where they left off in a book or video

Small configuration files in your custom format

How roaming works

• Data syncs for the user’s Microsoft account

• App uses data normally
