Customer

The client is a world’s leading semiconductor manufacturer.

Problem

Softeq’s long-standing customer was after an eligible Android software developer, capable of building robust IoT enabled PoC solutions. Drawing on the successful track record of past collaborations, the client engaged the team in the project involving wireless tech.

The client had an in-house developed solution — a board embeddable into sports garments. The idea was to turn the sports clothes made of the smart garment into an IoT system so that an athlete wearing smart apparel could obtain data on his/her physical state. Softeq undertook the project to develop a mobile demo app meant for performance stats tracking.

Solution

Softeq developed a smart apparel solution that works with sensors embedded on the inner side of clothes, including tank tops, gym shirts, pants or underwear. The system consists of a heart rate measuring device, sensor-rich sports garments, and Android-powered watch and mobile app that exchanges data with sensors over BLE.

The mobile software app prototype is a feature-complete demo app integrated with the client’s custom BLE environment. The solution allows for measuring heart beat and pulse rate, steps, distance and calories burnt. Lightweight and password-free, the application keeps the stats chart available immediately. The Android wear app supports the same stats set (except for pulse rate) and shows it in numeric output.

Challenge

High precision of heart rate detection was a strong evaluation factor, so the team carried out a dedicated analysis on the heart beat data quality. Given that the system was to integrate with existing device and firmware built on the customer site, Softeq focused much on fine-tuning the data transmission stability. As long as built-in electrodes captured much noise, the team furnished the app with filtering algorithms that help identify heart rate.

Methodology

In order to control internal work progress, the team employed Scrum.

Results

Softeq met both time and budget restrictions, thus aiding the client to obtain PoC smart clothing specifically designed for internal development teams. Happy with the delivery, the customer referred the team to a partner division looking to delegate an IoT project to a trusted service provider.
