As an application developer, you know your applications are only as effective as the platform on which they sit. That is why Nokia has developed Nokia N9. It has been designed from the ground up to streamline the interactions people will have with their devices and your applications. Nokia N9’s direct touch interactions empower object manipulation, while shallow navigation hierarchies ensure relevant content is easy to find and use.
We strongly recommend that you read these UX guidelines before you embark on the design and development of your application for Nokia N9 devices. However, these guidelines are not meant to replace detailed technical specifications – you will find those on Nokia Developer. Instead, they represent a description of the overall framework model for Nokia N9, explain relevant interaction rules and outline available framework support in an easy-to-read reference document.
It's best to use general accessibility guidelines as there are no specifications for accessibility. For example, do not use red text on a green background, use a large enough font and so forth.
Nokia has a rich history of third-party support, represented by its different platforms and device portfolio. Each platform presents a distinct opportunity. Please visit Forum Nokia where you will find additional guidance on choosing the right platform for your service.
