Aesthetic user interfaces ranking using fuzzy analytic hierarchy process (FAHP) approach

Abstract

In decision making, multiple approach can be applied to solve a problem according to its nature. Analytic Hierarchy Process (AHP) approach is one of them. AHP is widely used in both qualitative and quantitative problem solving. AHP however is unable to handle problem that are vague in nature, thus this is where fuzzy set is essential. Fuzzy refers to the uncertainty in decision making, it reflects the criteria of human that can be very ambiguous in deciding their preferences. Fuzzy Analytic Hierarchy Process (FAHP) method determine weight criteria and priorities of alternative in a structured manner through pair wise comparison thus eliminating the fuzziness of a problem. The aim of this study is to rank aesthetic user interfaces using the FAHP method in five (5) design attributes: contrast, consistency, balance, emphasis and alignment. The interfaces are very subjective; it could vary from a user to another. Thus, this study proposes a model using FAHP as a method to calculate the weight of each alternative in relation to each criterion to get the most aesthetic interface. The result of the study shows that contrast is the most important criteria in deciding aesthetic interface from five (5) experts that involve in user interface design domain. The model produce can act as a guideline in designing interface.
