Pulse: stay in your zone

Pulse is a wearable accessory and mobile phone experience that monitors your heart rate and helps keep you in your most optimal fitness zone.

Fitness performance made simple

There are a lot of heart rate monitors on the market today that are bulky and uncomfortable to wear (such as large chest bands), or that are undesirable for people who want a more fashionable solution to their sports activities (such as bulky watches). In addition, focusing on staying within your optimal target heart rate zone can help you burn more calories and reach your goals more efficiently. No constant calculation in your head. No bulky hardware. Pulse simplifies your heart rate performance and helps keep you in your zone, beautifully and discretely.

Know when you're in or out of your target zone, at a glance

Focusing on staying within your optimal target heart rate zone can help you burn more calories and reach your goals more efficiently. The experience simplifies heart rate monitoring by focusing on keeping you in your zone. No need to calculate your heart rate during your work out. The experience does it for you.

Making real-time feedback fashionable

Some people want a more fashionable approach to their fitness gear. Pulse is a fashionable approach to heart rate monitoring that can be worn as a piece of jewelry. It’s small, discrete, and you can comfortably wear it anywhere.

Connect to your friends and support group

The experience allows you to select your most optimal target heart rate to your needs and goals using the mobile app. Change it at any time. Connect to your friends and trainer to help keep you on track and share your progress.

Ring interaction
On the phone, select your target zone based on your goals. The ring is connected to the phone and provides visual and haptic feedback that helps you stay within your zone during your work out. If you’re in your zone, it pulses white. If you’re below it, it turns blue indicating that you’re too cold. If you’re above it, it turns red indicating that you’re working out too intensely.

Experiential Prototype

Experiential Prototypes are used to "test often and fail early" in order to iterate and improve new experiences early in the design phase. This makes it easier and more efficient to get a sense of the feel and interaction before investing in the development prototype. This experiential prototype was built using the new open-source Pulse Sensor that was recently developed and funded through Kickstarter. Custom software was created for the ring interaction and tested during a variety of fitness activities such as running, biking and gym use. Watch the video to see it in action during a 6 mile outdoor run.

The haptic feedback was initially too aggressive. It was adjusted so that it provided 3 taps when you're above your target heart rate zone and only 1 tap when you're below. This seemed to provide enough touch feedback without interrupting the flow of your workout. It was also just enough to nudge you to glance at the ring to see more specifically what zone you're in.

The light pulses to your heart rate when you're in your target heart rate zone. This mode is unnecessary when you're doing activities such as running since you simply glance at the ring rather than look at it for long periods of time. The pulsing does work really nicely when on a bike, especially indoors when your hand is placed in a similar location during your workout. In that case, it provides a beautiful way to visual your heart rate in real-time.

Squeezing the heart rate sensor too tightly against the finger lead to some errors. This is particularly problematic when on a bike. Holding the handle pushes the ring into the finger. This was improved when two wires were placed into the ring that kept the sensor from pressing into the skin too tightly. Consider the ID to solve this problem.

This prototype was not tested in rain or very wet conditions. Too much moister could lead to errors or short-outs. This will need to be considered in the development prototype.

    Pulse is so absolutely and essentially cool! I can’t wait until you have these available for purchase!!! I would LOVE to have one!

    Not only would these rings be useful for fitness, but for those like me who need to monitor their heart rate for health reasons. I am unable to run or do much exercise due to my physical disability, I do however need to keep track of my heart rate with a big bulky ugly watch. To be able to keep track of my heart rate and record it using the app, for doctor’s use in the future, would be great. The colour coding system is especially helpful, and lets my family know if they need to be extra watchful (ie. have the defibrillator on hand in case the worst happens).

    Thank you so much, I can’t wait until you have these available for purchase!

    This would be a great alternative to wearing the chest straps, so I will definitely be considering this as soon as one comes on the market.

    I can’t wait for this product, with heart issues this would be the perfect. I would be willing to be a beta tester,as well. My heart rate varies due to the effects of radiation treatment. I have to wear a sports watch, which is fine but not so nice when dressing up. This seems like a good solution. Thank you for your research on this project.

    I can see this being a great product for people with heart problem, such as uneven heart beats. It would be great to constantly monitor heart rate and would be a early warning system for user and their doctors.

    What stage of development are you guys in? I’m a marathon runner and biker and would certainly be interested in one or testing it.

    I’m 49 and I exercise at least three times a week by swimming with a High Level Masters group. I eat well and I’m not heavy but I just had a stent put in. I’m even more focused on a healthy lifestyle and understanding what is best for my heart. Pulse is the perfect solution for me but many if not all of my activities are in and around the water. I still surf along with my swimming and I have no plans of slowing down. I will be 1st in line to buy this product as long as I know it can be used all the time in a salt water environment. Love the idea!!!

    Car shopping can be very time consuming. There are plenty of cars you can look at, as well as a handful
    of factors to consider. You need to make sure you are
    aware of what you need to make it a better experience.

    Consider the following helpful advice for making things easier on you.

    Recently diagnosed with atrial fibrillation and tachycardia, I am looking for an inconspicuous way to monitor my heart rate – especially during exercise. I have small hands and wrists and would prefer a thin wrist band or – even better- a ring! Let me know when you get this on the market – I definitely want one.

    When I was growing up, I just assumed that everything in
    the grocery store was perfectly safe and perfectly
    healthy. People should be focusing on being healthy, not skinny, she said, and they should create strategies for reaching and maintaining a healthy circulatory, digestive,
    immune, and nervous system. When you eat fewer calories than you are burning off
    a lot of hard work. Cookie dieting to gain muscle is a logical response to weight gain simple carbohydrates and
    start eating foods that don’t have fiber.
