FreeMotion™ Architecture

  • Flexibly partitions among smart sensors, sensor hubs and application processor to support different power, cost and features;
  • Creates a layered and extensible framework to support rich contexts while minimizing computation;
  • Presents sensor fusion results and user contexts as virtual sensors in a simple-to-use API.

The FreeMotion Library is architected to support the evolving requirements of context aware devices. It can run directly on an application processor, or be embedded in a sensor hub, or have its functions distributed among smart sensors, peripheral microcontrollers and the application processor. This allows system designers to optimally trade off power consumption against computation and memory costs based on their product differentiation.

The layered framework makes it easy to add new fundamental contexts beyond Device Motion, Carry, Posture and Transport. Developers can also create new contexts by adding more layers of interpretation. For example, a pattern of Standing and Walking contexts may be re-interpreted into a “standing in line” context. By creating an extensible framework, the FreeMotion Library is well positioned for a new landscape of context aware applications.

 

On July 11th 2014, Audience completed the acquisition of Sensor Platforms. Audience believes the combination of its Advanced Voice and Multisensory Processing with Sensor Platforms’ technology places the combined company in a unique position to deliver compelling solutions based on the fusion of voice and motion.

Multisensory user interface with context awareness will bring fresh differentiation and end-user value to the market for smartphones, wearables and other mobile devices. Sensor Platforms has developed key technologies and software infrastructure in this space, and the combination of our engineering teams will enable us to rapidly scale our capabilities in context awareness-based user interface.

Audience welcomes the Sensor Platforms team and thanks all of its partners for their continued support during this transition.
