Design Principles for Creating Samsung Apps Content

UX Design Environment for Samsung TV Application

General mobile device application and TV application provide users with fundamentally different forms of experience based on each device and User Interface. When designing informative and interesting User Experience of TV application, understanding of the two following factors should be entailed.

  1. Environments for TV Viewing
    • Legibility of the information in observance of the viewing distance
    • Possession of devices for individuals or families
    • TV watching time and cycle for each user
  2. Control
    • Input of buttons on remote control necessary to watch broadcasting, which is the basic operation of TV and major application
    • Buttons on remote control is basically composed by four directional arrow keys, ENTER, RETURN, and EXIT.

How to Design a Great User Experience

  1. Purpose of Application in Itself

    How useful the application is to users and how much pleasure it gives them should be considered.

  2. Connection with the Use of TV

    As applications for mobile devices like Location Based Service which enables users to quickly access to information at user convenience, reflecting characteristics of mobile devices is preferred, it is desired to create new user experience through designing application linked with the experience in watching TV, considering TV viewing circumstance.

Design Principles for Creating Samsung Apps Content

Simple

  • Application is not always good just because it has a lot of features and information. TV screen should not contain too much information. The screen layout should be easily accessed by user friendly features, clear and conveniently arranged to use.
  • Operations and time for entering each level needs to be minimized and available to control.

Clarify

  • Accurate navigation for user operation is the most crucial among various factors in TV application.
  • If navigation is ambiguous, users always feel insecure, promptly close the application and they have a strong tendency not to revert to the application.
  • Especially, application should be designed for users to figure out where they are in the application. Fundamentally, actions of navigation such as Move, Return, Enter should be clear, and it can prevent them from losing their way.

User Control

  • Application should provide operational methods and corresponding intuitive structures appropriate for Input Device. TV has a restricted control method called “Remote Control”. Since remote control is not mobile like PC mouse, the structural design of application needs to be optimized for remote control.
  • Actions on TV OSD (ON Screen Display) followed by input of remote control are needed to come up to users’ expectations, and overall operational specifications are required to be coherent.
  • To achieve consistency, correlation of factors such as label and icon with actions should be guaranteed. Refer to the guidelines of Navigation Help to be described later.

Consistency

  • Consistency is highly related to improvement in Usability and Learnability. Operational buttons (PLAY, PAUSE, FF/REW, STOP) to play video in TV are applied to the application directly. Users can utilize and get the application more readily in use of existing information on operating functions.
  • Similar form of UI can not be applied to all applications as forms of application and traits of service vary. However, with securing consistency of components stated below, users are able to make use of application more easily based on common factors of TV control in different applications.
    1. Consistency of Button Operations

      There is no big restriction on button assignment, but in case users intend to allocate features to each button such as color button or simple menu on remote control, if the suggested buttons(ex. GREEN : Sorting, Preference, YELLOW : Check/Release) mentioned in the guidelines are allocated, application users are able to learn how to operate application simply.

    2. Consistency of Screen Layout

      Screen should be composed to provide information on application effectively, but each one line area indicating title on the top and Navigation Help at the bottom should be secured.

    3. Consistency of Interactions

      The identical way of interaction should be maintained in basic functions or screen factors like consistency of display location and style such as message popup, option popup (Ex, sub list), action window, that of directional navigation in contents list.

Feedback

  • When displaying an item which can be focused, focused status and selected status by operations from remote control are displayed separately.
  • When entering service, or the time to bring data in accordance with user input exceeds the specific criteria while using application, put a loading animation on screen in order for users to confirm that the page will be changed soon visually.

Aesthetic

  • Aesthetic design offers more convenience to users than normal ones. Irrespective of whether it is simple to use or not, aesthetic design looks simpler and it increases the possibility to be picked. Also, it is more effective and generous to lead positive responses compared to normal ones.
  • Unlike PC and mobile environment, it is necessary to consider TV oriented aesthetic design factors (color, resolution, screen composition) when producing application.

Mandatory Items

This item should be consistent with specifications of TV menu and TV application. Following items should be observed.

  1. Voice Control Command Order
  2. User Account
  3. Minimum Font Size
  4. Pop-up
  5. Action Window
