Responses to usability Semantic Differentials Sample Clauses

Responses to usability Semantic Differentials. Prototype Trials Participants were asked at two points (after a brief overview and then at the end of their use of PATHS) for their responses to a series of semantic differential scales, rating polar opposite experiences on a 7-point scale of +3 to -3, with a neutral 0 (zero) position at the centre. In this way initial impressions and final views of PATHS were captured. Figure 58 Initial and Final view, Prototype Trials Results to the sixteen semantic pairings by the Prototype Field Trial participants show a positive response to most aspects of usability evaluated, ranging from +1 to +2. Most participants rated Familiarity as one of their lowest points; this is to be expected in a prototype system. Speed of the system was also scored lower, and for the majority of participants this became worse as they completed their use of the system. Initially most highly rated usability aspects were: • Attractiveness • Organised • Interesting • Creative • Inventive • Useful Final views rated the following most highly: • Organisd • Creative • Likeable Almost all of the scores are slightly lower for final than initial responses, which would imply that the particiapants encountered some difficulties which impacted on their perception of the system.
