CSCI-588TLIB (Team 45) Project Status Review10/25/2005 Team 45 Timothy Etters - etters@usc.edu, ID = 8165 (Off Campus – Issaquah, WA) Nathaniel Yun – nyun@usc.edu , ID = (On Campus) Ramakrishnan Parmeswaran - ramakrip@usc.edu , ID = (Off Campus - New York, NY)
Topic Description • Project Name: (TLIB) Online Movie and Television Library Service • Description: The Movie/TV Library Service (TLIB for short) is a subscription based online service providing viewers instant (streaming HD video) or near instant (cached before playback) access to a comprehensive movie and television library (including complete archives of all episodes per show). • The service is made available to the consumer thru a device that viewers add to their home entertainment center that includes a hardware box that connects to the internet and your television set, and a remote control for input. • The key feature of this system is instant or near instant accessibility to any movie or specific television show or episode in the comfort of your own home, removing the need to either search across town for a particular movie rental, or wait by the mail for your Netflix rental to arrive. • The key innovation of this system is complete access to a comprehensive library of television shows including out of circulation programming, granting consumers the control to go back and watch past episodes that they missed of their favorite series. Freedom to watch a particular program or episode when you want. • The UI input is handled by a standard remote control similar to ones used for DVD players, televisions, TIVO, (which include the use of arrow keys for navigation). The UI output, is displayed on the television, showing the menus that users will navigate thru using the remote control. • Assumptions include a) wide availability of bandwidth to most consumers of this product, b) complete licensing of movie and television content from content owners (TV/Movie studios).

User Analysis Discussion: User Profile • The user of the TLIB system is essentially the television viewer. It is the same individual who knows how to use a television set along with devices such as a TIVO, DVD Player, or VCR. • The user can be between the ages of 10 and above. The user lives in a first world country where television and high bandwidth internet, cable, or digital satellite delivery systems are widely available. • Users are both male and female in genders. The user can be left or right handed, and can be color-blind. The user is any individual in the world that watches television on a regular basis. • The user can have a low level of computer literacy, and a minimal degree of typing skills. The knowledge space of the user should be equivalent to that of the average television and VCR/DVD player owner. • The user should know how to use a DVD remote control and be familiar with such concepts as play, pause, stop, fast forward, rewind, and DVD menu navigation using the arrow keys. With familiarity to such systems as the TV, DVD, VCR, the user should be able to use our system with minimal previous experience.
User Analysis Discussion: Dialog/Interaction Styles Selected • The dialogue style for our project is a combination of: Menu selection, Fill-in Forms, Function Keys, and Direct Manipulation. This combination will allow for the best mixture for our users to quickly and easily select and watch the content they desire. • We will not use Command Language and Natural Language since our product is a remote that has limited data entry. Our target users would be forced to learn a system that would be very unfamiliar to them and take much longer to adjust to using. • The basic psychology of our user is someone who wants to enjoy television content from their living room. They want to quickly and easily find the desired show and watch it. They will want to accomplish this with as small amount of button clicks as possible. • Most users will have knowledge of other television devices. However they will not necessarily be an advanced computer user. The task characteristic of using TLIB is a user daily operating our product to select the type of content to watch on television.
User Analysis Discussion: Task Analysis • The user’s task is to find a particular television show or movie to watch from the library, make sure it is the desired material to view, select that show or movie for viewing, then relax and watch the material selected. • The user will perform this task whenever the user selects a new show to view. Once a selection has been made the majority of the time is spent watching the material selected, requiring little to no interaction until after the viewing is over.
User Analysis Discussion:Environment in which our system operates • The environment of the user will be the location of the user’s entertainment center, which is usually found in the living room. • The user will normally be sitting comfortably on a couch or chair that is positioned several feet away from and centered with the television set and entertainment center. • The user will normally access the complete functionality of our system from the couch. • The user should not have to get up to access any features as they currently do not need to in order to turn on and watch television. • This environment usually does not include a table or desk or any comfortable place to rest a keyboard or mouse for input.
User Analysis Discussion: I/O devices selected and why • Input Device: A wireless infrared remote control similar to those found on devices like the television, VCR, DVD Player, and TIVO will be the primary method for input. Of importance are the up, down, left, right arrow keys which will be used for menu navigation and selection. • Key reason to use a remote control similar to those found on existing home entertainment system devices is to stick with existing standards and conventions that our users are already familiar with. There is a reason the DVD player remote is not drastically different from the Televion remote, or the TIVO remote. A different input system would require a longer learning curve. • Output Device: The Television screen will output both the TLIB’s navigation menu as well as the selected movie or television show. Audio output can also be directed to the home entertainments audio system (audio receiver). • Key reason for selecting the television for output for both the navigation UI as well as the video is simply, majority of time, user will be looking at the television screen. Minimize the user’s time looking at other additional devices (i.e. separate navigation screen away from the television).
Visual DesignSummary Style Guide • The TLIB projects main goal is to make a product that is easy to use by individuals with no or little computer skills. This product should have simple menus and navigation, large easy to read fonts, and a color scheme that is easy to read and understand.
Visual DesignMenus • Menus should be large, simple to navigate with arrows (such as “main menu” in example one). • Their descriptions should be short and concise. • Each page should have no horizontal scrolling and minimum vertical scrolling when necessary. A list of search results is the only instance where vertical scrolling should be used. • The main start page should have no scrolling.
Visual DesignColor • There should be a consistent use of calm colors throughout all the menus. • The submenus should be color coded (i.e. different color back ground should be used for each submenu). • The product should use about 5 different colors for menus and text. • The font colors need to be easily readable compared to the background and menu colors.
Visual DesignFonts • The system should use the same font throughout. • The font size should be large enough to be read easily on a screen with the resolution set to 800x600.
Visual DesignUser Typing • The user should be required to do minimal typing. • Typing should only be required when searching by keyword.
Visual DesignNavigation • There will not be a menu bar. • The menu tree should be at most 3 levels deep. • The ability to go back, or up one level should be on every page. This allows the user to return to the main page with at most 3 button pushes.
Visual DesignTraining • This product should be easy to understand. Minimal if any training should be needed for new users to maneuver through the menus.
TLIB: Main Menu Browse Local Archive Search Online Library View Downloads in Progress Queue Configure Settings and Account Information TLIB: Main Screen Layout Design Product name at the top so users know which application/device this screen belongs to. Display name of the current menu we are on. Navigation Arrow. This icon represents the current selection. Users navigate by moving this icon up and down in the menu to select their choice. Arrow movement is done using remote controls 4 arrow buttons. Enter button performs action on current selection. Menu items. User can select one of the listed menu items to enter that screen. Menu items are also color coded with different color schemes acting as a way to visual distinguish pages. Large fonts and menu buttons are designed to be easily readable and viewable on a conventional, low resolution TV set. Selecting this icon will close the TLIB system. On other sub pages, icon acts as a back button. Exit Each page has a specific color theme. For this mockup, blue was chosen for the main menu. In other sub menus, menu selections that bring us back to the main menu will be color coded blue as well.
Comments / issues / complaints / assumptions • Tools used or planned to use • Flash will be the primary tool used for development. • Lessons learned • Apply principals learned in class they work! • Plans for the rest of the semester • Refine the UI and make it the best we can.
