Coubertin Rings Update

The Android Experiements are composed of a gallery of creative open source projects developed for the Android platform, and were introduced as a way to “encourage more developers to challenge how we interact with the devices we use every day.” In the spirit of the experiments, we set out to challenge how users interact with their Android Wear devices, and in doing so challenged none more than ourselves.

There were design questions: What opportunities exist beyond the more traditional mouse and keyboard or touchscreen input? What types of gestures and interactions are natural and intuitive, yet novel and compelling? Can we give users control over their experience while still surprising them?

And there were engineering questions: What types of input are available? What technologies should we use? How do we deliver a consistent product across different types of hardware?

We submitted three watch face designs to the gallery, all of which have a unique interactive component that leverages built-in sensors on the watch.

Fathom Watch Faces
  • Coubertin Rings is inspired by Pierre de Coubertin’s Olympic rings, and promotes daily physical activity. A new ring is formed each time the wearer takes a step. It bounces playfully around the screen and forms larger rings as the user takes more steps.
  • Bouncing Isaac pays homage to Isaac Newton’s prism experiments, which demonstrated that white light is not “colorless”, but rather, a blend of many different colors. Geometric patterns dance across the screen, influenced by the movement of the wearer throughout the day.
  • Gaze Effect elicits the feeling that the watch is looking back at the user whenever she looks at the watch, a reference to Jacques Lacan’s definition of “gaze”. Animated eyes appear on and disappear from the screen based on how frequently the user looks at the watch.

The Coubertin Rings design in particular presented obstacles that set it apart from the other two. First, it relies on a step counter, which is not a dedicated hardware sensor. (Examples of dedicated hardware sensors include the accelerometer and gyroscope.) Rather, it is a “software-based” sensor, which processes input from the hardware sensors to calculate second-order information. Not only does this introduce latency into the interface, it adds an additional layer of variability and complexity already present in the landscape of Android Wear devices. We found that watches with varying Android versions calculate steps very differently, which made it difficult to design a predictable and consistent experience on all the various devices. In addition, it is the only one of Fathom’s watch faces that delivers quantitative feedback to the user, so it’s crucial that the feedback is accurate.

Watch Faces in Action

 

We modified the Rings to use the step detector— a faster but less sophisticated version of the step counter— so that the display will update in real time when the user is looking at the watch. When in ambient mode, it reverts back to the step counter. In this way, we are able to strike a balance between instant feedback and accuracy. To mitigate the issue of variability across devices, we adopted the same step counter that Google Fit uses.

We soon learned that the Google APIs come with their own set of challenges and complexities, both for developers and users. For instance, Google Fit must now be activated on the watch in order for Coubertin Rings to count steps correctly. In the end, though, we were able to replace the individual device step counters with a call to a universal, device-independent API. We also get the added benefit of step count being stored in persistent memory. This means that the Coubertin Rings counter won’t reset if the user switches watch faces, and it will even show steps that were counted on other devices as long as they’re connected by the same Google account.

After releasing the watch faces on Google Play and reading feedback from users, we were surprised to learn that Bouncing Issac– the simplest of the three to develop– is the most popular design. This poses a new question: What depth and complexity of interaction do users expect in a watch face? The purpose of experimentation is discovery, and participating in the Android Experiments has led us– and will hopefully continue to lead us– to discover the challenges and opportunities of developing for wearables.
