Mobile phone use is pervasive, yet little is known about task switching on digital platforms and applications. We propose an unobtrusive experience sampling method to observe how individuals use their smartphones by taking screenshots every 5 seconds when the device is on. The purpose of this paper is to incorporate ...

Daily engagement in life experiences is increasingly interwoven with mobile device use. Screen capture at the scale of seconds is being used in behavioral studies and to implement "just-in-time" health interventions. The increasing psychological breadth of digital information will continue to make the actual screens that people view a preferred ...

Life experiences are increasingly intertwined with digital devices, suggesting screens as a preferred, if not required, data source for behavioral studies and health interventions. Text Information Extraction from digital screenshots is then a key prerequisite to the overall accuracy of analyses regarding media behaviors. This unique image data set offers ...

Epidemic monitoring systems engaged in accurate discovery of infected individuals enable better understanding of the dynamics of epidemics and thus may promote effective disease mitigation or prevention. Currently, infection discovery systems require either physical participation of potential patients or provision of information from hospitals and health-care services. While social media ...

Social media has been considered as a data source for tracking disease. However, most analyses are based on models that prioritize strong correlation with population-level disease rates over determining whether or not specific individual users are actually sick. Taking a different approach, we develop a novel system for social-media based ...

Social media is emerging as a powerful source of communication, information dissemination and mining. Being colloquial and ubiquitous in nature makes it easier for users to express their opinions and preferences in a seamless, dynamic manner. Epidemic surveillance systems that utilize social media to detect the emergence of diseases have ...
