Mobile Applications

BCA provides a full range of electronics and software research and design services for a variety of mobile applications and hand-held deivces.

Apple iPhone CPR Coach

BCA had previously designed hardware and other components for a hand-held, pocket-sized CPR coaching device for Bio-Detek, Inc., a wholly owned subsidiary of ZOLL Medical Corporation. The Pocket CPR uses an accelerometer and complex algorithms to measure the depth and rate of chest compressions while a rescuer is performing CPR.

The device fits under the rescuer's hand and provides audio and visual feedback to coach the rescuer to perform continuous compressions at the proper depth and speed, as well as instructions such as when to give breaths. (See our case studies, CPR Coach Device Design and Cell Phone Application Demo.)

Because the Apple iPhone contains a built-in accelerometer and a rich user interface, BCA and Bio-Detek set out to determine if the algorithms for monitoring CPR compression could be implemented on the iPhone.

BCA used the client's algorithm as the core functionality for the application. We tuned the algorithm to account for the lower resolution of the iPhone accelerometer. We also used the algorithm in a different way to provide feedback to the user in the iPhone's media-rich interface.

The new application utilizes the iPhone's built-in animation engine, more interactive audio cues, and a new visual/tactile interface.

Future goals include adding new elements such as training and instructional components.
