Since its founding in 1993, the TECO research group has been directing a multitude of projects across a wide range of research topics which can be divided into three broader Research Fields: Analytics, Human-Computer Interaction, and Sensors and Systems.
With partners from relevant industry sectors and the core idea to tie research and industry closer together, all of these projects are tightly linked to one or multiple Application Areas, most importantly Big Data, the Internet of Things & Industry 4.0, Mobile & Wearable Computing, and Smart Cities.
With the rise of Ubiquitous Computing, computers and therefore sensors have become omnipresent in our daily life. Likewise, Industry 4.0 strategies have introduced sensors in the supply chain and production processes. The TECO research group develops and analyses improvements in how these sensors collect information, connect with each other, and interchange and process data to enable innovative processes throughout society in business, Smart City, industrial and private settings. Other projects study how people interact with electronic devices and which tools can assist individuals or teams in different environments to benefit from technological advancement. Finding new forms of preparing and conveying information by using Augmented Reality or special feedback methods suited for particular contexts is essential to maximize the efficiency and usability of these computer systems.

Calmables is a closed-loop infrared earable designed to explore thermal biofeedback for relaxation support. The system uses heart-rate data from a smart ring to establish an individual baseline and identify periods of elevated physiological activation. When a personalized threshold is reached, the earable delivers a subtle, localized warming stimulus to the ear using infrared light. A companion smartphone application coordinates the interaction and visualizes physiological changes, while independent temperature limits and communication fail-safes ensure safe operation. In a preliminary placebo-controlled evaluation with 18 participants, the active prototype received higher ratings for perceived relaxation and recovery support than an identical-looking placebo device. Calmables demonstrates how physiological sensing and unobtrusive thermal stimulation can be combined to make biofeedback tangible and support brief moments of recovery.
