This questionnaire is about VR controllers detect player’s arm movements to simulate
drawing as an interaction trigger and its playability in the virtual space. Questions may
involve some privacy of the person filling in the form. (This part needs to be improved.
Please give us any suggestions if you don’t mind.)

II. Contents Design (Questions are answered by 1-5 scale, 1- mostly agree, 2 – agree, 3 – not
agree or disagree, 4 – disagree, 5 – mostly disagree. Please allowed us to ask a reason if

1. The interaction of drawing as a trigger is essential in this Magic Brush and helps the
   player to understand the story as well as adding to the playability.
2. The interaction of drawing has to be as flexible as possible in terms of motion
   capture.
3. The ‘trajectory’ I draw during the interaction should be visually obvious in the contrast
   with the visual space around you.
4. Visual/audio/haptic prompts are required for the start, failure, and success of the
   interaction.
5. Visual/audio/haptic prompts are required for the valid range of the interaction.
6. Operating instruction of the interaction should always be displayed in the player’s
   sight.
7. The appearance of the player’s hand model in the virtual space is necessary to
8. increase immersion and enjoyment. The brush model gives the player a more
9. immersive feel.
10. Simple patterns (e.g. letters) improve the efficiency as a trigger in the interaction
11. compared to complex patterns with lots of detail.
12. The pattern is drawn in a very simple shape (e.g. a circle) it will make the whole
13. process less enjoyable
