Design Principles for Creating Samsung Apps Content

UX Design Environment for Samsung TV Application

General mobile device applications and TV applications provide users with fundamentally different experiences, based on the characteristics of each device and the User Interface. When designing an informative and interesting user experience for TV applications, the following key factors should be taken into account.

  1. TV Viewing Environment
    • Text legibility depending on the viewing distance
    • Possession of devices by individuals or families
    • TV viewing hours and patterns of each user
  2. Control Environment
    • The remote control that is necessary to control the TV channels and apps
    • The four directional arrow keys, together with ENTER, RETURN, and EXIT are the main buttons for navigation

How to Design a Great User Experience

  1. The Actual Purpose of the Application

    Consider how useful the application is to the user, and how enjoyable it should be to use.

  2. Consider how useful the application is to the user, and how enjoyable it should be to use.

    The best applications for mobile devices often take advantage of in-built features to offer services such as Location Based Services, which enable users to quickly and conveniently access relevant information. So when designing applications for use on a TV, it's a good idea to create new user experiences by linking applications to the normal TV experience, taking into account the environment in which people may watch TV.

Principles for Designing Apps for Samsung TV

Simplicity

  • A more complicated application is not necessarily a better application. The TV screen shouldn't be covered in too many features or too much information. The layout should be user-friendly, with clear, easy to access features that are arranged in a convenient way.
  • The operation of an application must be kept simple without requiring complex navigating to sub-levels. The operation must be simple enough for the user to understand and control without referring to a manual.

Clarify

  • The most crucial factor when designing a TV application is to include clear and accurate navigation for user operations.
  • If navigation is ambiguous, users will feel confused and insecure. They will promptly close the application, and are unlikely to ever use it again.
  • In short, users should always know exactly where they are within an application. Fundamental navigation actions such as Move, Return, and Enter should always be clear, to prevent them from losing their way.

User Control

  • Applications should operate in an intuitive manner that takes into account the input device used to control them. The main input device for a TV is the remote control, and because this functions very differently from a PC mouse or touch screen, the structural design of the application needs to be optimized for ease of use.
  • Actions carried out on the TV screen via the remote control need to meet users' expectations, and the overall operational specifications must be coherent.
  • The remote control button labels and icons must always fit with the actions that they perform. The Key Guide detailed later in this file should be followed at all times.

Consistency

  • Consistency is closely related to improvements in Usability and Learnability. Buttons (PLAY, PAUSE, FF/REW, STOP) that are used to play video in TV can be applied to the application directly. Re-using functions wherever possible makes it easier for users to learn and use your application.
  • It's not always possible to use the same UI for every application, as forms of application and traits of service vary. Ensuring the consistency of the components stated below, however, enables users to become familiar with common controls, and to use applications more easily.
    1. Consistency of Button Operations

      There are no major restrictions on button, voice command, and motion assignment, but following the function guidelines helps users to quickly and easily learn how to operate an application.

    2. Consistency of Screen Layout

      The screen should be laid out to effectively provide information in each application. Maintain the screen layout recommended in the Guideline for content type and application characteristics to ensure a familiar user experience. The same 1-line of space must be reserved for the display positions of the title area at the top and the Key Guide area at the bottom of the screen.

    3. Consistency of Interactions

      The application must maintain a consistent interaction method and on screen display elements that are common to all applications, including location and style of message popups, option popups( sub-lists, etc.), and action windows as well as directional navigation in the content list.

Feedback

  • When displaying items that can be selected using focus, the status of items must be displayed in a manner that allows the user to easily identify if an item is under focus or if an item has been selected by remote control operations such as pressing the ENTER button.
  • When the time required to open an application or load data exceeds a certain period, a loading animation must be displayed to provide visual confirmation that the screen will soon change according to user's request.

Aesthetic Considerations

  • Aesthetic design makes applications look easier to use while increasing the chances of being used again by the user. Aesthetic design is also effective way of generating positive user responses to an application.
  • Unlike the PC and mobile environments, applications designed specifically for use on a TV must pay particular attention to the associated aesthetic design factors such as color, resolution, and screen composition.
