In Your Face Lap Times!

Rather than using expensive, sensitive, hi-tech hardware (like a head-up display or mini lens-projector), Jun Yin’s Viewpace goggles offer a simple extension of a timer for swimmers to track their lap times. The extension is slim and lightweight yet rigid enough to stay intact during rigorous underwater movement. While there is a level of resistance it creates in relation to hydrodynamics, this is negligible compared to the current method of stopping entirely to check a stopwatch located at the edge of the pool!

    Hi, Mario
    1) The drag has minor impact on swim speed. If you can swim 1m/s, you will swim 0.9962m/s with this goggle. You can find the detail of our calculation according the fluid dynamics (
    2) Yes, a better aerodynamic design of watch will reduce the drag significantly. Now, this is the first version and we do not have much funding to manufacture a new timer. Will be improved in the future.

    Hi Jun Yin, thanks for taking the time to reply to my comment, the analysis you posted shows that the drag is really very insignificant. I hope that you can further explore the design of the time piece. This is a promising concept over all.

    Will I be able to preorder this anytime soon?

    Just saw that you are already shipping, any way to ship to Europe?

  • Jun Yin says:

    Hi, Mario
    Since you are the first one from Europe, I can send you one for free. Leave your shipping address here

    BTW: I just check your website, I like your hairdryer

    These use a number of techniques to move the natural oils down their hair such as boar bristle
    brushing and ‘scritching’ between washes. Refrain or limit the amount of heat
    applied to your hair through the use of blow dryers,
    curling irons, straighteners, etc.
