1. CS 352, W12 Eric Happe, Daniel Sills, Daniel Thornton, Marcos Zavala, Ben Zoon ANDROID/IOS RPG GAME UI

2. PROJECT OVERVIEW The purpose of this project is to design a user interface (UI) for a mobile game application that runs on various touch screen Android/iOS devices. The application in question is a Roleplaying-genre game (RPG) where the player moves a character in the world and performing turn-based events.

3. There are thousands of games in the market that use Android/iOS touch screen capabilities for users to control the game. Most have poorly developed UIs Created with an attempt to create a control structure similar to gamepads used for console gaming. There has been a lack of consideration of how to effectively design a touch control system that is engaging and satisfying for the players of these games What's the problem?

4. By creating a usable UI, android and iOS market shoppers would have a larger variety of options as to which games to download. The user would also have a more pleasing experience playing the game instead of experiencing frustration and anger due to the poor usability of the interface. How would this help Users?

5. The target users for this project are people (gamers, students bored in class, etc.) who find it interesting to play fantasy RPG/action games that use Android/iOS touch screen capabilities for users to control the game and meet the following criteria.  Know how to use a general Android/iOS application.  Own and android phone or some way to run Android/iOS applications.  Have access to the network to download the game.  Do not have a disability that prevents them from performing common Android/iOS tasks (reading text and graphics, performing multi-touch gestures, etc.)  Can read English Target Users

6. User Input Interviewed two users Both users are “typical” college students Both users own a smartphone device Both users play RPG games Both users prefer to play games in short sessions rather than long ones User #1 does not like complicated interfaces User #2 hates touch commands that are close to the physical device buttons User #2 prefers simple character interactions In conclusion: Both users prefer simple interfaces with straightforward commands

7. UI Evaluation: Planning We want to make sure our users know how to equip weapons, use the “wheels”, and save the game. We also want the user to remember what items, weapons, and spells are equipped. Our UI elements must be away from the device buttons to avoid accidentally closing the application. This also includes not cluttering the UI Touch events and actions should be simple and intuitive to the user.

8. UI Evaluation: Results Using CogTool, we tested our users with the prototype of our UI:  Our users were able to find the main menu button and select it  Our users were able to find where items and weapons can be equipped  However, both users went to the Items menu first to equip weapons  The wheel menus, though confusing at a glance, were understood of their use  Because the menu buttons where highlighted, our users knew which menu they were in  Our users intuitively knew how to fight monsters and understood touch screen commands  Because our battle menu is different, our users criticized that the ‘menu’ button was misleading and should be called ‘battle menu’

11. Arranged Buttons on the top and mainly to the left side of the screen.

12.  Changed the way in which the user was given feedback from the buttons (menus)  Originally when a user would enter a menu there would be buttons that were auto highlighted.  confusion for user  Made user believe his options were restricted to highlighted buttons.  Found user was not being given the appropriate feedback trough user interview and evaluating the interface using Nielson's heuristics.  Violating the principle of feedback  Justify the new design of our menus with the principle of feedback Button Highlights only after User clicks on it

13. ELEMENT SELECTION In our original design, the item/magic/enchant wheels would default to some element in the wheel. Our new design defaults with no element selected, which requires the user to choose an element. This reduced confusion as to what element was actually in use.

14. Easy way to undo/go back Every screen has a back button to take user back to the game. Don’t want user to feel “trapped” on any screen Supported by Heuristic Evaluation and User Interviews

15. Menu Consistency Menus have consistent appearance throughout Internal Consistency Buttons all round and look more clickable Chunking utilized to group like options Main menu button removed during battle, replaced with specialized mini-wheel Prevent users from doing some things during battle, such as saving

16. Menu background was changed to a semi-transparent view of the game Selected list items are now highlighted clearly Colors / Background

17. New large icon indicates the option the user has selected Reduce previous confusion about this Selection Feedback

18. System provides concepts from RPG games that are familiar to the user  Wanted to emphasize recognition vs. recall.  Better for the user to spend more time playing the game than spending time learning how to player.  If user can understand how to play easily then it is more likely that user will continue playing the game.  Determined this using Heuristics evaluation focusing on Match between system and the real world

19. CONCLUSION From our previous prototypes, we have made improvements to our user interface.  Evaluating our users gave us an idea of an interface RPG gamer can use  From prototyping, we are able to determine the button layout and touch commands for our users  Our core UI principles:  feedback (such as button highlighting)  visibility (finding the buttons)  Consistency (along RPG games)  We created a final prototype that follows these principles
