OTHER FUNCTIONS - THE USER INTERFACES WILL BE PRODUCED AS MEDIUM-FIDELITY WIREFRAMES. DEPENDING ON THE NEEDS OF THE PROJECT TEAM, INTERFACES MAY BE DESIGNED FOR SMARTPHONES, TABLETS OR CONVENTIONAL (LAPTOP/DESKTOP) FORM FACTORS OR ANY COMBINATION OF THE THREE. THE INTERFACES WILL BE DESIGNED AND REFINED THROUGH PARTICIPATORY DESIGN SESSIONS WITH TARGET END USERS (E.G., VETERANS, FAMILY CAREGIVERS, CLINICIANS). FOR EACH OF THE FIVE APPLICATIONS THAT WILL BE DESIGNED, FACE-TO-FACE SESSIONS WILL BE HELD IN 3 LOCATIONS IN THE CONTINENTAL UNITED STATES. EACH LOCATION WILL BE VISITED TWICE. DURING THE FIRST ROUND OF VISITS WE WILL FOCUS ON UNDERSTANDING USER NEEDS AND DESIRED CAPABILITIES AND BEGIN MODELING THE INTERFACES. DURING THE SECOND ROUND OF VISITS WE WILL FOCUS ON USER CONFIRMATION OF THE PROPOSED DESIGNS.
