Aristotle Said “Happiness is a State of Activity” — Predicting Mood Through Body Sensing with Smartwatches

We measure and predict states of Activation and Happiness using a body sensing application connected to smartwatches. Through the sensors of commercially available smartwatches we collect individual mood states and correlate them with body sensing data such as acceleration, heart rate, light level data, and location, through the GPS sensor built into the smartphone connected to the smartwatch. We polled users on the smartwatch for seven weeks four times per day asking for their mood state. We found that both Happiness and Activation are negatively correlated with heart beats and with the levels of light. People tend to be happier when they are moving more intensely and are feeling less activated during weekends. We also found that people with a lower Conscientiousness and Neuroticism and higher Agreeableness tend to be happy more frequently. In addition, more Activation can be predicted by lower Openness to experience and higher Agreeableness and Conscientiousness. Lastly, we find that tracking people’s geographical coordinates might play an important role in predicting Happiness and Activation. The methodology we propose is a first step towards building an automated mood tracking system, to be used for better teamwork and in combination with social network analysis studies.

DEGREE CONDITIONS FOR GRAPHS TO BE FRACTIONAL （a, b, n）-CRITICAL GRAPHS

Let G be a graph, and a and b be integers with a ≤ b. A graph G is called a fraetional （a, b, n）-critical graph if after any n vertices of G are deleted the remaining subgraph has a fractional [a, b]-factor. In this paper two degree conditions for graphs to be fractional （a, b, n）-eritical graphs are presented, and the degree conditions are sharp in some sense.
