Emotion tracking with wearable devices is an interesting area of research that many are looking into with the goal to change the way people interact with tech, as well as to better understand their own feelings. Smartwatches and fitness trackers, can track physical signals that change with emotional states. Signals like heart rate, skin conductance, and body temperature, which often change when someone experiences emotions like fear, joy, or stress.
Researchers believe that combining these signals with others could allow wearables to interpret more complex emotional patterns. Such advancements could make wearable devices even more useful in understanding human emotions. The ability to recognise emotions could soon become normalised in the world of wearable technology. Devices that currently track fitness and stress levels could improve and update by bringing emotional awareness in everyday life.
What Studies Have Looked At Emotion Detection?
Recent studies have tested how wearable devices can measure emotional responses. One research group examined changes in skin conductance while participants watched videos designed to trigger fear, family bonding, or fun. The sensors showed that fear caused the fastest and strongest reactions, while bonding emotions developed more gradually, combining joy and sadness.
The findings confirmed that physiological signals can help distinguish between emotions, though the emotional spectrum studied was narrow. Current research is limited to a few emotions, leaving much of the field unexplored. Researchers believe combining skin conductance with other signals could result in more accurate readings of emotional states.
Although the experiments had limitations, they showed that physiological signals could be used to measure emotional responses in real-world scenarios.

What Sensors Are Used To Detect Emotions?
The sensors in wearable devices play a key role in emotion tracking. Electrodermal sensors measure changes in skin conductance linked to sweating. Heart rate monitors and temperature sensors track other physical changes tied to emotional reactions.
These sensors gather data that researchers and developers can interpret. For example, an increase in heart rate combined with higher skin conductance might indicate excitement, fear, or stress. Smart devices are already using these technologies to track stress, and expanding their use to emotional analysis is the next step.
How Could Emotion Tracking Be Useful?
Wearables that can track emotions have many potential applications. In healthcare, these devices could help with stress management and mental health. For instance, real-time monitoring might encourage users to take breaks or try relaxation techniques when stress levels rise.
In education, emotion tracking could measure student engagement, helping teachers adapt their methods to keep learners interested. In transportation, drivers’ emotional states could be monitored to prevent fatigue or frustration from affecting their focus. PersonaliSed technology is another area where this feature could shine. Devices could adjust music playlists, gaming experiences, or user interfaces based on the wearer’s mood, creating a more enjoyable and intuitive experience.
Could Wearables Support Mental Health Treatment?
Wearables with emotion detection capabilities could change how mental health is monitored and managed. With being able to identifying stress, anxiety, or emotional imbalances in real time, these devices could provide insights that are difficult to capture in traditional therapy settings.
A wearable device could detect patterns of heightened stress throughout the day and let the user or their healthcare provider know. This data can help therapists give clients better treatments, such as personalised relaxation techniques or mindfulness practices. It could also help users in recognising emotional triggers for better self-awareness.
Emotion-tracking wearables might also assist in managing conditions like depression or PTSD. Early detection of emotional shifts could prompt users to seek help before their mental health deteriorate.
