Multimodal Sensors


Smartphone provides information regarding social interaction (e.g., number of phone calls and SMS messages) and geolocational movements via GPS sensors.

Wearable Devices

Wearable devices provide health-related signals from the users: number of steps, time of working out, time of sleep, etc.

AR/VR Devices

While players enjoy the augmented and/or virtual space, we uncover the way in which they interact with physical/virtual information space.


Through monitoring ocular behaviors, including fixations, saccades, pupil dilation, and scan paths, we understand users' information seeking styles.

fMRI Senser

Scholars use fMRI (Functional Magnetic Resonance Imaging), which measures brain activity by detecting changes associated with blood flow, to study cognitive function engaged in human information behavior.

EEG Sensor

Similarly to fMRI, EEG (electroencephalography) sensors enable wider use of various research devices. For example, we can collect new dat by examining users in their home environment.


Miller Behavioral Style

The Miller Behavioral Style identifies the information seeking behavior (ISB) of individuals under threat; Monitors (M) prefer a higher volume of information input before meeting a stressful event and suffer less psycho-physiological arousal when they have information, while blunters (B) prefer less information and suffer more arousal when they have a high information input.

Big-Five Personality

The survey examines five broad dimensions of human personality: (1) Openness to experience, (2) Conscientiousness, (3) Extraversion, (4) Agreeableness and (5) Neuroticism.

Williams Social Capital

This theoretical model defines two kinds of social capital; bridging and bonding. Through bridging, people broaden their world views and open up opportunities for new information or new resources, while bonding is an exclusive type of social capital that occurs when strongly tied individuals (e.g., family or very close friends) provide emotional or substantial support to each other.

Risk/Time Preference

Individual preferences (risk or time preferences) are critical in determining economic behavior and socioeconomic status, such as investment and insurance utilization, etc., which in turn indicate income and health accumulation.
