Pulse rhythm

Pulse rhythm

Pulse rhythm refers to the pattern of pulsations within specific intervals, offering valuable insights into the regularity or irregularity of the heart's beats as observed through the pattern of pulsation within specific intervals. A regular pulse exhibits a consistent heart rate with uniform waveforms and pulsation force, variations of which can be classified as normal, weak, or bounding.
Conversely, an irregular pulse pattern is termed dysrhythmia, stemming from disruptions in cardiac muscle...

Area of Science:

Human-computer interaction
Wearable technology
Biomedical engineering

Background:

Ubiquitous computing requires advanced user interfaces and context-aware services.
Bio-signal acquisition systems are crucial for connecting users to computing environments.
Existing systems lack personalized service delivery based on real-time human status.

Purpose of the Study:

To develop a wearable system for sensing physiological data and determining emotional status.
To enable personalized service execution based on recognized emotions.
To support ubiquitous computing services through emotion recognition and feature extraction from bio-signals.

Main Methods:

A wearable system comprising three subsystems: physiological data sensing, human status awareness, and service management.
Sensing photoplethysmography (PPG), galvanic skin response (GSR), and skin temperature (SKT) signals via a data glove.
Utilizing nonlinear mapping and rule-based methods for emotion determination and feature extraction for mobility.

Main Results:

Successful development of a wearable system for personalized services.
Demonstrated ability to sense physiological data (PPG, GSR, SKT) and determine emotional status.
Automated activation of services based on recognized emotions, enhancing personalized user experiences.

Conclusions:

The developed wearable system effectively provides personalized services in ubiquitous computing environments.
Physiological signal analysis, including feature extraction considering mobility, is key for accurate emotion recognition.
This approach offers a novel solution for context-aware and personalized ubiquitous services.
