About this project
When babies are not feeling well, they cry because they cannot say what is wrong. To give parents peace of mind, we need a device that can quickly and accurately measure temperature and track historical data. As parents ourselves, we could not find anything on the market that could satisfy our needs. That's why we created Wishbone to help parents monitor and track temperatures more efficiently.
Wishbone is a non-contact thermometer that works with smartphones to improve the way we measure and track temperatures. It is easy to use and can accurately detect body temperature in under 2 seconds. Through its app, Wishbone can store historical data which can be viewed at a later date for analysis and reference. This feature is particularly helpful for parents monitoring their baby's recovery from illness and for couples that are trying to conceive. Wishbone’s unique Y-shape is designed for better viewing angles while operating it and it is the only smart thermometer that is compatible with both Android and iOS devices.
Why We Named It Wishbone
The first thing you will notice about Wishbone is its unique Y-shape design that is very different from other thermometers. After many design experiments and feedback from users, we felt it may be hard for users to operate a straight-pointing sensor and see the screen at the same time.
Therefore, we chose a 45 degree angle tilt for the sensor design because that is the most natural viewing angle for human eyes. This makes it much easier to operate and view the app simultaneously and in turn you'll receive more accurate feedback.
The Y-shape design also allows users to point Wishbone in the direction that is more comfortable for each situation, Users can simply rotate Wishbone to find the best way to point its sensor.
The other branch of Wishbone contains small lithium batteries that power the sensor. They ensure robust operation and make Wishbone compatible with both Android and iOS devices. This was the only way to ensure the widest compatibility as many phones have different electrical output from their phone jacks. The battery is very small, easy to replace and can be readily found in common stores. Together, the angled sensor and battery design give Wishbone its unique personality and features.
The core function of Wishbone is to detect temperature using an infrared sensor. Wishbone is noninvasive, reliable and versatile for many applications. It can accurately measure body temperature by measuring forehead skin and examine liquid temperature from surfaces in just a few seconds. While measuring, Wishbone does not emit any radiation or sound as it uses a passive sensor. Wishbone can also measure environment temperature by pointing it toward the sky or ceiling. Both Object and Ambient modes are still currently under development.
Body Temperature Mode
As mentioned above, Wishbone can help parents quickly and accurately measure their baby’s body temperature. It works best when the sensor end is pointing directly at the forehead and is less than 5cm away. It takes less than 2 seconds for Wishbone to acquire data and determine the body temperature. The readings can be displayed in either Celsius or Fahrenheit.
Temperature data can be even more useful when compared to past records. That’s why we added the function to create profiles for individuals to separate and track each person's data. Using historical data, parents and couples can create charts to help them understand their situations and make better decisions. For example, couples can identify ovulation periods by looking for a small but clear spike in female body temperature. This feature integrates Wishbone's hardware with the app running on a smartphone and truly makes it a smart thermometer.
Object Temperature Mode
Wishbone can detect the temperature of either solids or liquids. This is a very handy tool for parents to check milk's temperature or to see if bathtub water is too hot. For it to work, just enter the Object mode and point Wishbone at a target that is within 5cm of the sensor to gather and calculate temperature data. We are still developing this function as the Object mode requires a different set of sensor calibration to the Body mode.
Another exciting Wishbone feature is the Ambient mode. In this mode, Wishbone can detect environment temperature by using its sensor to gather data from the surroundings. Parents can use this feature to find out ambient temperature and decide whether they need to add more clothes to their baby. For it to work, users would need to tap on the Ambient mode and press scan. There is no need to point the sensor in any particular direction, but we usually recommend pointing Wishbone's sensor upwards. Like the Object mode, the Ambient mode requires a different set of sensor settings and is still under development.
A traditional thermometer takes at least 30 seconds to get a good measurement and that may be impossible when the baby is not feeling well and moves around. While an ear thermometer is faster than a traditional thermometer, it still requires contact and doesn't track or analyze temperature data.
Wishbone works much faster, is less prone to user error and is smaller than both traditional and infrared thermometers. It also doesn't require contact, so it won't disturb your baby's sleep or be contaminated. A major part of Wishbone's development was to significantly reduce the size of the thermometer and the circuit while maintaining excellent accuracy. Many design experiments were done to minimize the size as much as we possibly could while ensuring efficient operation.
Origin of the Idea
As a father and a baby product store owner, I know the hassle of taking a child's temperature all too well and so do my teammates. My parenting experience and the feedback from my customers led me to believe that there is a need for a small, easy-to-use thermometer that measures and monitors temperatures using a smartphone. That's how we came up with the idea for Wishbone.
How Wishbone Works
Using a passive infrared sensor and advanced algorithms, Wishbone can quickly and accurately measures temperatures from many different sources. The app uses highly optimized codes for processing sensory data in each detection mode to achieve both speed and accuracy. Wishbone does not emit any light or radio-electrical energy and certainly doesn't contain mercury that can cause health concerns. The Wishbone measures temperature from a short distance and it is safe and very useful in many applications, especially for parents with young children.
Wishbone will be in Lime color by default if we hit our funding goal. If we meet stretch goals, more colors will be available.
The Object and the Ambient modes are both under active development. Because we have limited resources, our programmers focused on getting the Body mode ready first. We expect to deliver the Object and Ambient modes in July 2015. However, if the below stretch goals are met, we can hire additional help to speed up development and we can deliver those modes at the same time as Wishbone ships.
Thank you for your help thunderclap, now Wishbone comes with carrying pouch.
How We Got Here
We spent several months designing the first generation of Wishbone before switching to the Y-shape design. While the Y-shape makes it easier to use Wishbone, it also poses much tougher engineering challenges for us from a structural and industrial design perspective. We had a long debate on the cost and benefits of redesigning; the team had already spent the majority of our resources on the previous design. In the end, we felt that it was worthwhile to make the sacrifice and put in additional time and resources to make Wishbone the best we can. We moved ahead with the new design in Aug 2014 with much less resources, but we made great strides towards making Wishbone a reality. At the moment, we are done with design and have working prototypes, but our resources are running low. That's why we are here on Kickstarter to ask for your support so we can finish and launch Wishbone.
The bulk of the design works are done and we have been testing for a while. We already have working prototypes and are undergoing very thorough testing that is a prelude to a small test production run. We expect to complete testing by February and finish the app’s development by March. The goal is to start production in April 2015.
Like many parents, JoyWing team members are professionals with full-time jobs and family responsibilities. We have extensive experience in hardware and software development and we are dedicated to making Wishbone a great product. We truly believe that Wishbone can really help other parents and that is why we spent our free time working on this project. It has been an exciting journey for us as we are nearing the finish line. We hope that Wishbone launches successfully and gives parents some much-needed peace of mind.

Risks and challenges
Wishbone's hardware has undergone 2 generations of design and testing and we are confident about its readiness and reliability. The injection mold is almost finished and we are getting ready for small batch production. The risk is that molding and sourcing parts for production may take longer than we anticipated and thus cause delays. Furthermore, Wishbone requires a highly optimized algorithm and well-designed app to make it fully functional. While both the app and the algorithm are functional, we are still working out the bugs and making them run more efficiently. In addition, Wishbone comes with a battery and custom law for batteries varies from country to country. We will do our best to send the package as you indicated, but we cannot be responsible for custom delay, tax, duty or any liability stemming from your country's custom process.
Wishbone is not a medical device. It is a multifunction thermometer that is great for detecting body, object and ambient temperature when used within its designed parameters. Please consult your doctor for medical questions and advice.Learn about accountability on Kickstarter
