2nd Usability Test

Usability test was conducted with about 12 people in a several groups. I tested with four group of people for the first test and then a few group of people later on at different times.
In the beginning most of them were trying to follow displayed animation instruction on the screen. Most of them understood how to play instrument with animation instruction. It took them a bit of time to play instrument. When they got used to play with them, tried to control sound to make harmony with other sound came from other people. In addition, they are interested in visual information on the screen, created while they were playing instrument and sound. From my observation i found that most of users were confused about visual on the screen. It effected on users to use instrument. For instance, they did not know where they need to place their instrument. After usability test i interviewed them with these qustions which are as follows;

1. Do visual feedback information and sound effect users?
2. Is animation intruduction clear to follow or not?
3. What users think about multiful play?
4. Do they feel interaction with other people while they are playing an interactive installation?
5. Is it easy to play without learning?

In conclusion, all of them agreed on visual feedback information and sound are interesting and unique. They also appricated that ability of control sound and activity performace. In addition, male users were prefer to playing drum instrument because of the sound. Female users from Eastern, played istrument with large movement than Male users from Western. Most of them are agreed on that the instruction could stay on the screen rather than fade out.


From this 2nd usability test. My team and I need to modify both product and visual. For product, i need to redesign clapping instrument to make it simple and keep identity with instruction.
And i need to consider to get rid of stics from drum instrument for usability. Visual also need to change, squre and arrow images make user confuse whether they should place their instrument. Animation instruction also need to modify to stay on the screen rather than fading out.
