The solution

The first product is called OtoSense, bassed on a technology called SIR, for Sound Intelligent Recognition. OtoSense is an application running on various mobile platforms. It records and analyses background sounds and sends notifications to its user if any noticeable sound is recognized (fire alarm, doorbell, etc.). It also allows the user to record specific sounds he wants to be noticed about. The product’s specific user interface is adapted to people who might as well suffer from visual disorders.

OtoSense is an innovative solution, far more efficient and less expensive than the preceding systems.

Pentalog set up a dedicated team of 5 engineers based in Chisinau (Moldova) to support the development of the solution. They first worked on the improvement of the first prototype and then took over the development of the iOS and Android versions of the application, and its connection with the Pebble smart watch.

The results

The client’s next project consists of a global sound identification search engine.
OtoSense is pleased with Pentalog’s collaboration which started in 2014. Pentalog’s dedicated teams continue to support Otosense’s teams in the development of new projects.

Key success factors:

  • high level of flexibility and efficiency due to the Scrum organization of a senior Scrum Master
  • a strong, proactive team that proposed many improvements which included a senior developer with a strong background in algorithms related to recognition
  • Sébastien Christian, Founder & CEO of OtoSense, stated that at Pentalog he found “a stable, robust, and solid team of developers, with a good head”.
