alerthet

Alerthet is a term used in speculative design and early human-computer interaction research to describe an integrated wearable and services ecosystem that continuously monitors contextual and physiological signals to generate proactive alerts for the wearer and designated contacts. It is not a single product but a family of systems that can be embedded in wearables, smartphones, and ambient devices. The guiding aim is to improve safety and situational awareness by anticipating events such as dehydration, fatigue, risky motion, or early signs of illness, and delivering timely notifications through visual, haptic, or auditory cues.

Technically, alerthet combines passive sensors (heart rate, skin temperature, accelerometry), optional biosensors, and environmental sensing (sound, light) with data fusion and lightweight on-device or edge-cloud models. Users configure alert criteria, escalation rules, and sharing preferences, including which contacts receive alerts and under what circumstances. Privacy and data minimization are central design considerations, with options for local processing and encrypted transmission.

History and usage: the concept appeared in research and design discourse in the 2010s and 2020s, with pilot projects in workplaces, sports training, elder care, and outdoor activities. It is typically explored as a supportive augmentation rather than a replacement for human judgment, and as such researchers emphasize transparency and user control over notification behavior and data sharing.

Criticism and challenges include privacy concerns, the potential for overreliance or alarm fatigue, accuracy of predictions, and the need for clear regulatory and ethical guidelines in health-related deployments. Proponents argue that well-designed alerthet systems can reduce risk, enhance response times, and support autonomous decision making in complex environments.
