A Heuristic Checklist for Second Screen Applications
(i-com: Vol. 18, No. 1, 2019) Lohmüller, Valentin; Schmaderer, Daniel; Wolff, Christian
This paper presents domain-specific heuristics for second screen applications and the development of a heuristics checklist to enable a more intuitive and structured application of the created heuristics. The heuristics presented were developed on the basis of Nielsen [12] Ten Usability Heuristics in a research-based approach using specific literature and a focus group. In order to evaluate the quality of the derived checklist, a heuristic evaluation of a second screen application with five users was carried out and its results compared to a user study with 20 participants. This resulted in an average validity of 0.5 and a high completeness of 0.74. The harmonic mean of these values results in an F-measure of 0.6 with an equal weighting. This value speaks for a sufficient validity of the created heuristic checklist in the first iteration.
