From the gallery walk I appreciated getting different perspectives on our designs. Some things that I realize we need to take into account are different sized bodies, specifically chest sizes. Another thing that we need to think about is how the device will change with weight inside. For the vest design in particular this is a challenge if the weight is not balanced front to back and side to side. It might slip on the body. This design seems to be one one we are settling on to move forward with, one reason being vests are already seen in mainstream fashion. On the other two designs we could have been more explicit in our descriptions as they are less obvious as to their use.
