Main Study
Our research question is to find an adequate task corpus with fitting metrics to describe photo applications and is therefore exploratory. During our pre-study we gathered needs of users and created tasks on these results and findings literary findings.
Tasks
Our tasks are the following:
Our photo corpus contains 60 photos.
Metrics
We are using the following metrics:
Approach
To make sure our tasks and metrics are able to gather whether a photo application fulfils the user's needs, we are testing them with Google Fotos.
We also want to ensure that our tasks work for various UIs. For this, we are comparing the tasks on a desktop and mobile UIs.
20 participants are pseudo-randomly assigned to an UI. Before a participant fulfils the tasks, he can take as much time as he needs to get familiar with the fotos and the application. This should help to reduce effects of pre-experiences.
The following variables are the resulting of this experiment design:
To get a deeper understanding of the user's experience, the participants are asked to answer the SUS and Attrakdiff - survey.
