“Stirr is a mobile app that uses the accelerometer to capture and record motion so it can be incorporated into 3D animations.”
In the first round of testing most users pressed “record”, then extended the phone out to begin drawing the rectangle, resulting in the above path.
By adding a countdown with accompanying vibration for each stage, the user has the opportunity to get their grip positioned while giving them time to get the phone to their paths starting point.
After the inclusion of the countdown users much more frequently achieved the above result.
Problem: animators have no access to low cost, easy to use motion capture technology.
Solution: With Stirr, animators draw a path in the air with their phones. Stirr captures this path and exports it to a 3D animation program, giving them quick and easy motion capture data to use in their animations.
Ummmm...: it does what now? The app is a lot easier to understand if you can see it in action, so below is a 39 second animation made to communicate the value and concept to animators:
“Animators communicate their ideas by acting them out: swooping, bouncing, and whooshing their hands around to illustrate the motion and timing they envision.”
User Flow: Building a user flow from early sketches helped me spot ways to improve the user experience, such as contextually activated controls.
This wireframe examines the Settings screen more closely, highlighting the tooltip that explains the path smoothing control.
This wireframe highlights an example of various controls selected states.
High Fidelity Mockups: These higher fidelity renderings help better communicate the value, concept, and aesthetic of the app to stakeholders and developers.
Conclusion: User testing indicates this app fills a need and professional animators would be interested in incorporating it into their workflow.
I’m a little obsessed with understanding and clarity. I think that motion can be incredibly meaningful in UX, and I want to show you how. I appreciate design that is user centered, elegantly functional, and aesthetically beautiful, and I want to help put more of it out into the world.
