Stress affects people on a very basic level. While for most casual activities the changes might not be as noticeable, it still contributes to the overall state of health. And if you are dependent on fine motor control (anybody make trips to the rifle range on a regular basis or play hard core video games?), you may find that simple stress can affect you more than you realize. Our nervous system and fine motor control state can be a good measure of our overall physiological state of being. It should not be surprising that our sense of control can vary each day depending on our health and outside influences. Now, thanks to the mechanical abilities of the iPhone, you can measure your current ability of steady control. The challenge is to simply hold your iPhone in your hand with your arm outstretched and steady. If you can do this easy sounding task for one minute, you pass the test. However, if your arm moves too much, the count starts over. And over. Once you raise your arm and have the phone in position, it will start announcing the count every five seconds. Until then, tones indicate that you do not yet have it level. Why level? Because that is the position that creates the greatest challenge with gravity. Sounds simple enough, but the iPhone senses slight movement that you may not be aware of making. After a few count resets, fatigue becomes a large factor in your success. Of course, there are some people who have a steady hand seemingly all the time, though few in number. If you are curious how you rank, one way to find out is to take the StongArm challenge. For an additional challenge, consider setting up a course to walk while trying to beat the clock. Simple movement adds another level of complexity to the process. You can also check out the state of your friends and colleagues Now, we do not condone the use of StrongArm to help win arguments, nor do we suggest use it to prove a point, but we are sure that you can find creative ways to use this capability. Thank you for looking at Pockster Strongarm!
