A young tech company, based in Northern Ireland who took on the challenge of building an innovative new assisted living service that enables elderly people to live independently in their own homes. Using a smartphone app, a wrist strap, and a base station, Kraydel provides real-time updates for relatives checking on elderly loved ones. The app tracks daily movement, ambient temperature within the home, whether they have taken appropriate medication, and flags any issues. The service also provides elderly people with peace of mind, with help just a click away.

Kraydel required an innovation partner to help them design and build the product and service, which presented several technical challenges. For example, one of the main features of the product is ‘real time event communication’, which ensures immediate changes in the elderly person’s condition are reported to their relatives – e.g. their heart rate drops, or they have fallen over, or they have been sleeping for too long compared to normal patterns. The ‘real time event communication’ function created the need for a real time data processor, with high volume data support to handle the ‘millions of data points per second’ that Kraydel devices generate. Furthermore, the Kraydel platform also needed the ability to notify relatives and emergency services in emergency situations. This required a tool capable of alerting certain sets of people for each elderly individual – all of whom may have different preferences when it comes to receiving notifications.

WSO2 Data Analytics Server (DAS) was selected for its ability to analyse data in real time so alerts would happen in a time sensitive manner. It allows configuration of different types of event receivers, so different messages can be added, and ensures that Kraydel is highly configurable with other software/hardware components. The DAS also supports predictive analysis of the data which Kraydel can use to detect future health risks in the elderly people it serves. The WSO2 Enterprise Service Bus (ESB) was important for connecting different software components making up the Kraydel platform. For example, if the DAS generates an alert, it is important for this to reach the right people in the right way. Mitra Innovation helped Kraydel to develop the technology behind the business by taking advantage of WSO2 components to both design the platform and undertake the development work.
