Exploring critical usability factors for handsets
Abstract:Handsets are being transformed from the traditional cellular phone to an integrated content delivery platform for communications. Their increasing capabilities and value-added features provide more utilities, and at the same time, make the design more complicated and the devices more difficult to use. The objective of this study was to explore and identify the critical factors that predicate the handset's perceived usability. An online survey was conducted by using a seven-point Likert-scale structured questionnaire tailored to measure the user's perception of the usability level of their current handset. A total of nine usability dimensions were derived from the results of exploratory factor analysis. The total variance explained by these nine factors was 65.20% of the overall variance of the data. Relationships between the nine usability factors and handset design features were described by regression models.
