I then tested my design on people and asked them about the grip. I realized that I still need to tweak the grip further as some people were focused on how to hold the object. This caused me to think about textures and I added the rougher pattern on the bottom of the flashlight to show people that they were supposed to hold that part. I also added the on and off switch as a slide forward. Originally, I thought that a slide sideways would be more natural. However, through testing, I realized that it was not intuitive enough and people felt that it was not very natural.
