Compare these two designs when there are 4 candidates and predict the relative speed of performance and error rates. Support your choice by a thoughtful argument.
The State of Maryland is developing a web-voting interface. For selecting the candidates, one design (RB) is a set of radio buttons and another is (CB) a combo-box (drops down when selecting the scroll arrow icon), both using standard fonts at 10-point size.
Sketch out one design/diagram each for the radio-button based solution as well as the combo-box-based solution. Handwritten is fine. List 4 candidates running for office. One method to obtain the answer is a very lightly controlled set of experiments, where you time a few people running through the election process. Also consider obtaining a fresh (unbiased review) from a friend, classmate or colleague who can provide objective feedback. If time permits, prototype this interface and see if the machine-executable solution changed your view from the paper-driven, low-fidelity prototype.
