scenarios

In addition to the traditional usability methods, such as think aloud, performance testing, questionnaires, focus group, participant observation, interview and heuristic evaluation, there are many other methods, such as paper prototyping, co-discovery, video feedback, remote test and so on.

Most of the usability tests can be carried out in the usability lab, but a small part of them in the use context. Below are 4 possible scenarios for lab tests.

scenario 1: performance testing (performance measurement, task based testing)

Performance testing also referred to as performance measurement or task based testing, is one of the classic usability methods. This method aims to collect quantitative data. The subject receives tasks to solve. Such data like the number of errors, duration of the solution of the tasks, the percentage of successfully completed tasks and the number of calls for help.

scenario 2: paperprototyping

Paperprototyping is a very effective usability method where subjects test a product with paper version. So you can evaluate a product before it is implemented. All the necessary human-computer interfaces are drawn on paper.

szenario 3: video feedback (video confrontation)

Video feedback also video confrontation, consists of two parts. In the first part, a subject performs some tasks. The subject is not verbalizing his thoughts. The face of the subject and the screen will be recorded by cameras. In the second part, moderator and subject see the recordings together. The subject comments now his approaches and actions. Also the second part is recorded.

szenario 4: co-discovery (constructive interaction)

Co-discovery, also constructive interaction, is a variant of the think-aloud method. Two or three users solve the tasks together and discuss with each other.
