Bracelett containing spare oxygen for extreme situations in big wave surfing.
User Interaction In critical Situations the biggest demand to the product is intuitive interaction. Position Looking at the possible movements of the body the most intuitive action appeared to be having the oxygen fixed on your rist. Position valve On the bottom: + better protection - hitting the nose On the top: + more intuitive Tactile feedback Eyes are closed under the water which brings in the necessity to communicate the postion via tactility. The valve can not stick out due to possible injuries. Solution: Using hard material for the top of the valve and very soft for the surrounding. Interaction valve Danger of breathing all the air at once Solution: One bite opens only one aircontainer Storage A big amount of the time the products we have are not in use. This shockresistant package is keeping the lifesaver protected during non-action times. Trust Which form makes the user trust technology? A person in panic will use up to twice as much oxygen under water. With this device you are more likely to keep calm while saving energy under water. - If trust into the product is archieved, it works without being activated. - More trust - less acceptance After some rough physical calculations of how big the bracelett had to be I had to size it up to make it look and feel more trustworthy. As the first prototype then looked like an electronic ankle tag, some curves have been added to give it a more dynamic look. Transparency Users encountering a new product are eager to learn about how the inner parts of the products work. To communicate the inner mechanisms a semi transparent material was chosen for the shell and the three aircontainer are painted in bright signal colors. Medical Function: Pure Oxygen is toxic as it creates Radical oxygen particles in the blood. Although three breaths are not harmful. Variables Given: Compression = 20 BAR oxygen level = 99% normal oxygen level in air ? 20% Volume of a Breath: during physical activities = 1,0l - 1,5l Oxygen in a heavy breath: 1,5l * 20% = 0,3l Volume Compressed: 0,3l * 20 bar = 15cm3
