Scale and rating criteria are configurable for the project, e.g. “good” – “bad”, “convincing” – “not convincing” etc.
RTReval can be integrated into an existing online survey infrastructure.
The ratings of a user (precise to a second) are saved and can be combined with the data of the survey. In addition to the assessment, pause / switchover and commentary actions can also be logged. In addition to the evaluation, pause-/ switching and commentary actions can also be logged.
Upon request, the assessment can be preceded by short questions (for example, age, gender, etc.).
