They say "content is king." But, "context is kingier" when it comes to designing great smartphone and tablet mobile apps. Don't make the mistake of thinking that mobile app design is just about a smaller screen size or choosing the right development technology. Content and context are both important to designing great user experiences, but mobile amplifies context on five critical dimensions: location, locomotion, immediacy, intimacy, and device. Understand each dimension of Forrester's mobile context to design mobile apps that will make your users say "I love this app!"
Forrester LLIID: Location, Locomotion, Immediacy, Intimacy, And Device
Location. People use apps in an unlimited number of locations. And not all places are the same. A user may be in a quiet movie theater, at home in the kitchen, on a train, or in the White Mountain National Forest. Contrast this with desktop computers, stuck in places such as an office cubicle, home office, or kitchen. Laptops provide some mobility but are larger and less able to provide the immediate access of instant-on mobile devices such as smartphones, eReaders, and tablets. Location is a key dimension of context, driving different needs for users depending on where they are. Fortunately, GPS-equipped smartphones can use a geodatabase such as Google Maps to determine precise location.
