Initial User Tests
This week we tested our newly built paper prototype on three users. We gave each of them a short introduction and asked them to each complete the three following tasks:
Task 1: Changing Volume
First of all we wanted to know how they would change the volume of the music or their part. All of them told us unanimously they would like to control it by changing their distance to the screen. Moving away from the screen should lower the volume.
Task 2: Trigger special effects
The second task was to think of gestures or poses to trigger some special effect. In our team we initially thought to trigger some effects by crouching down, this was not a gesture any of the users would have tried by themselves because it is a quite unnatural movement while dancing. They instead suggested gestures like touching their own hands, moving the head and turning their back to the screen. To initiate a crouching gesture, a visual hint was proposed.
Task 3: Pass instruments between users
Last but not least we requested our users to pass the different instruments to each other. Every user intuitively tried this by touching the other players’ hand. This confirms our initial design decision to be a good practise.
Some users pointed out that we have to be careful with gestures that need to put an arm above the head for a extended amount of time because this gets exhausting pretty fast.
Furthermore, two users prefer first person to have full control over all instrument simultaneously until a second person joins the game.
Mostly all of the suggestions concern the gestures and movements that control the music. Like we already learned in our interviews, they should easily incorporated into dancing so we shouldn’t assume that positions such as crouching down might be tried without additional hints. We therefore introduced a new visual element that invites the user to try new and unusual gestures, like in the following picture.
Furthermore, additional gestures like moving the head or turning the body away from the camera should be implemented to trigger special effects. These are being ideated now.
To address the additional feedback, we will design the controls in such a way that a single user has the possibility to control every aspect yourself as long as no other player entered the game. Additionally, fatigue of arms are a concern when implementing the final gestures.
