Sensor Device Arbitration

Article: Sensor Device Arbitration

Traditional fitness tracking wearable devices have many features for following and reporting on individual activities. This is generally done by means of communicating

with a smart phone or tablet-type device for displaying status and reporting data. As the technology and market place for wearable devices continues to grow, we believe that consumers will put more emphasis on the accuracy of reporting the types of activities being performed - while balancing form factor, processing, battery life, and attractive user interfaces.

For the most part, the approach of low-energy communication from a wearable device to a smart device is accurate for detecting the various types of activities you may be engaged in on a daily basis. However, accuracy appears to decrease when engaged in activities that use other body parts to perform. This is primarily due to the device orientation and placement which results in restricted motion of sensor data. For example, a device worn on the wrist may not be as accurate detecting cycling, rollerblading or strength training due to the inability to detect movements associated

with these activities. This is in addition to other environmental factors which are dependent on the sensors within the device itself - such as GPS positioning and elevation.

The quality and accuracy of device data collection is highly dependent on the number and class of sensors included within the device itself. This poses a tricky balancing act for wearable developers. The more sensors packed into a wearable device, the more battery consumption and processing it wi...
