A high fidelity prototype was developed using Adobe Flash and ActionScript 3.0 after deciding on a design of the mobile phone application for Tradesmen.ie following user research. This prototype comprises of the interface design based on the user research, sketches, wireframes and other mock-ups produced during the project. This high fidelity prototype allows users to interact with the application and gain a sense of the interactions that it facilitates. Due to the approach to the project, it was decided that the high fidelity prototype will be desktop based. The testing and evaluation was undertaken with existing users of Tradesmen.ie, as well as tradesmen not registered yet on the site. Click here to view the prototype.
