Wearables are small devices that you can wear close to your body, as you would wear clothes and jewelry. These devices can monitor several telemetric signals, such as heart rate, 3D motion and temperature. Combining this data offers insights about your whereabouts, health and fitness or living patterns.
Dialog created a device integrating six sensors: an accelerometer measuring forces in all different directions, a gyroscope measuring the rotational direction, a magnetometer measuring the heading of the magnetic north, a pressure sensor determining for instance elevation, a humidity sensor and a temperature sensor.
We have created an app that reads out six different sensors and displays these real-time in different graphs. The data can be interpreted and displayed in different ways. For instance, we use the data of a 3D accelerometer to display the movement of the device by moving around a 3D cube in the app. Gyroscopic data is used to display the rotation around 3 axis, visualized by a 3D sphere.
The device also offers fusion data, combining data from multiple sensors into quaternion data, enabling us to determine the actual orientation of the device with much greater precision. We use the famous Utah teapot to represent the orientation of device in the app.
