Features Record emotion, intensity, and notes Visualize data in chart/graph form Export data to a personal computer Record/track medications (name, dosage, and duration) View previous mood and medication entries Set alarms/notifications to prompt user for input

Design Process Our group decided to use a individual design process where four of our members produced prototype designs:

Comparing Prototypes Similarities Three tab layout for main screens Slider for mood input Basic layout of Mood Input and Graph Screens Differences Main menu screen/Use of Android menu screen/Tabs Emoticons/Text for mood selection Calendar/Menus for date selection Date Range/Number of days to view for graphing data Medication input

Combining Features Tab structure more intuitive than Android menu Making mood input the default tab Scrolling popups chosen over scrollpanes Combining medications & alarms with calendar Combining functionality with graphs Range of dates available to graph

Mood Input Screen Record date & time: Datepicker Slider from 1 to 10 of intensity Spinner (drop-down) to select descriptive mood Optional note to record data

Graph Screen Time Period to be displayed: Spinner (drop-down) Medication to be displayed: Spinner (drop-down) Line Graph/Circle Graph: Make Graph overlay appear Export Data: To an address

Calendar Screen Calendar: Select dates to see medication/mood for that day View/Edit Medications: Medications on secondary screen View/Edit Alarms: Alarms on secondary screen

Video Demonstration

Usability Testing Pre-Test Questionnaire: Name Age Android Experience Visual impairments 2 simple tasks requiring use of a single screen 2 advanced tasks requiring use of and navigation between multiple screens Post-Test Survey: Ease of use for each screen (1-9 scale) Best/worst aspects of application

Usability Testing Results

Usability Testing Results (continued) Specific user feedback: Certain features were hard to locate due to poor organization/labels Feedback should be offered when using the mood input slider. Color and design should be improved to make the app more visually appealing. Readability of graphs needs improvement.

Final Status Functional user interface in need of minor improvements Minor interface improvements: Color & visual style Relabeling of buttons Consistent font-sizes, button positions No back-end database

Future Development Redesign the tab structure Research set of moods that can be selected Implement a backend database to store mood, medication, and alarm data according to dates Implement dynamic graphing functionality Implement /export functionality Tie alarms/notifications to device notifications
