Interactive AR

Experiments with Google Tango and Tilt Brush

Project Time: Mar 2017            Primary Tools: Unity 3D, Project Tango, Tilt Brush

In these experiments, I focused on exploring interaction possibilities with the phone’s built-in sensors to allow users to control their AR experience and engage with AR environment.

Interaction Experiments

Vibration – Collision Based Vibration Feedback

I set the cube object a tag called ”target” and added a “rigid body” on the sphere. So when the sphere hits into the cube it triggers the vibration in user’s hand. This gives the uses a realistic feeling of collision in AR.

The buzzing sound in the video shows the phone’s vibration.

Motion Tracking – Accelerometer

This video shows that the phone measures acceleration and moves the cube correspondingly:

Tilt Brush – Stroke Simulating

The stroke paths in Tilt Brush are being played back in AR:

Cat and Balloon – 3D Depth Sensor

The balloons were made with Tilt Brush and then imported into Unity. They moved along a pre-assigned path. When the balloon passing by, the cats we placed on any surface will look at it.
