As you can read here we had decided to temporarily remove hand tracking to speed up our development process.
Initially we had planned to only use controller input for one/two sprints, but we have since tested and we have decided that it is not only in our best interest but also for the end user, to continue to use controllers instead of hand tracking.
We asked people that have tested our product with hand tracking and with controllers whether they preferred one over the other and the majority of test participants said they preferred the controllers. You can also see that in the results of our questionnaire in this article.
Reflection
What I learned from this is that you should not always listen to one persons opinion (in this case the teachers saying we should keep hand tracking) and that you should always test, because we all thought that hand tracking would be the preference of the users but they said the opposite and that gave us the final push to continue with controllers. After we had clear test results the teachers also accepted our decision more, because we had visible proof instead of only our own opinions.
