ABSTRACT

IN MACAO'S HIGH-DENSITY URBAN ENVIRONMENT, TRADING SECOND-HAND GOODS AND SERVICES HAS BECOME AN IMPORTANT WAY TO PROMOTE RESOURCE RECYCLING AND COMMUNITY INTERACTION. DUE TO LIMITED LIVING SPACE AND CONCENTRATED POPULATION, THE DEMAND AMONG MACAO RESIDENTS FOR SECOND-HAND TRADING PLATFORMS IS INCREASING DAY BY DAY. HOWEVER, EXISTING PLATFORMS MOSTLY FOCUS ON LARGE-SCALE MARKETS AND RARELY TARGET MACAO'S ACTUAL COMMUNITY CONDITIONS TO EFFECTIVELY OPTIMIZE THE INTERFACE AND INTERACTION DESIGN FOR SECOND-HAND SERVICE TRANSACTIONS. THEREFORE, THIS STUDY TAKES MACAO AS THE INVESTIGATION AREA AND FOCUSES ON THE INTERFACE DESIGN OF COMMUNITY-BASED PLATFORMS CENTERED ON SECOND-HAND SERVICE TRANSACTIONS. IT EXPLORES HOW TO IMPROVE EFFICIENCY AND USER EXPERIENCE THROUGH INTERACTION DESIGN, WHILE STRENGTHENING COMMUNITY CONNECTIONS TO SERVE LOCAL MACAO. THIS STUDY ADOPTS A MIXED-METHODS RESEARCH APPROACH. FIRST, A LARGE-SCALE QUESTIONNAIRE SURVEY WAS CONDUCTED TO COLLECT THE USAGE BEHAVIOR, SATISFACTION, AND FUNCTIONAL PREFERENCES OF MACAO RESIDENTS REGARDING SECOND-HAND TRADING PLATFORMS, SERVING AS THE SERVICE FOUNDATION FOR THE OVERALL DESIGN. SECOND, FOCUS GROUPS AND INTERVIEWS WERE USED TO GAIN A DEEPER UNDERSTANDING OF THE EXPERIENCES AND NEEDS OF USERS OF DIFFERENT AGE GROUPS DURING ACTUAL OPERATIONS. MEANWHILE, THIS STUDY COMPARATIVELY ANALYZES THE INTERFACE CHARACTERISTICS OF MAJOR SECOND-HAND TRADING PLATFORMS IN MAINLAND CHINA, HONG KONG, AND TAIWAN TO SERVE AS A REFERENCE FOR DESIGN DEVELOPMENT. THE RESEARCH RESULTS WILL YIELD AN INTERFACE DESIGN PROTOTYPE FOR A SECOND-HAND TRADING PLATFORM SUITABLE FOR MACAO'S URBAN LIVING CONTEXT. WHILE MAINTAINING TRADING FUNCTIONS AS THE CORE, IT INTEGRATES AUXILIARY COMMUNITY MUTUAL AID MODULES TO SUPPORT DAILY INFORMATION EXCHANGE AND NEIGHBORHOOD INTERACTION, THEREBY MAY SUPPORTING LOCAL COMMUNITY EXCHANGE. IT IS HOPED THAT THIS STUDY CAN PROVIDE A PRACTICAL REFERENCE FOR THE INTERACTION DESIGN OF COMMUNITY- BASED DIGITAL PLATFORMS AND RESPOND TO THE ACTUAL NEEDS OF LOCAL COMMUNITIES IN MACAO.
