Comparação de Métodos de Avaliação de IHC sob a Perspectiva do Autor da Interface

Abstract

Although academy recommends execution of HCI evaluation methods by third party specialists, some companies are unable to follow them. How do small companies conduct evaluations with little knowledge about HCI and design? Is it relevant for the interface author to evaluate his own HCI solution? This work presents a case study that examines the experience of IT professionals conducting their first HCI evaluations. We compare heuristic evaluation, communicability evaluation method and usability test from interface author’s perspective, considering involved time, materials and people, results and faced difficulties. Even on non-ideal conditions, the interface author found relevant results from formative evaluation. He found 27 problems in heuristic evaluation, 20 problems in communicability evaluation method and 4 problems in usability test to guide solution improvement.
