Tools and Methodologies Exposition

An inaugural Tools and Methodologies Exposition ran concurrently with the Digital Media and Developing Minds Congress. This new program reflects the Institute's desire to encourage a paradigm shift in the research community. Studies based on parental surveys, media diaries, and other indirect methods have helped frame important questions. So, too, has research conducted on small groups of children under controlled laboratory conditions.

However, the Institute believes that answering those questions will take something more, such as real-time monitoring, advanced imaging techniques, continuous, large-scale, and long-term measurement of children's media exposure and its positive and negative effects on young bodies and minds. The technology needed to do such research - from low-cost sensors to advanced methods of data management and analysis - is emerging now. The Second National Congress and Exposition on Digital Media and Developing Minds showcased these advances. Read more about the Exhibitors and their tools and methods below.

Center on Media and Child Health

The Center on Media and Child Health (CMCH) at Boston Children’s Hospital (BCH) is an academic research center whose mission is to educate and empower children and those who care for them to create and consume media in ways that optimize children’s health and development. Founded in 2003, CMCH focuses on media as a powerful environmental health influence, like the air we breathe and the water we drink. We seek to understand the positive and negative health impacts media can have and find ways of making media the most positive possible influence in children’s lives.”

Comprehensive Assessment of Family Media Exposure Consortium

Comprehensive Assessment of Family Exposure (CAFE), a novel tool which measures household media use through a web-based survey, time use diary, and the chronicle passive sensing app. CAFE captures the content and context of early media exposure and addresses the limitations of prior media measurement approaches. All three measures are collected online, which allows scalability. The survey covers 10 topics relevant to the child’s immediate media context, including household composition and demographics, parental mediation of media use, parent attitudes toward media use, and access to and regularity of use of different devices frequently used in the modern household. The online 24-hour time diary extensively details media use as a primary and secondary activity at given points in a child’s day. 

The passive sensing tool continuously records mobile device usage on tablets and smartphones in the home. The purpose of this presentation is to introduce how we have used our new tool in different settings. Based on preliminary analysis of CAFE data collected from ~250 participants, we conclude that the time use diary and passive sensing app contribute additional information because parent global estimates alone are not sufficiently accurate.   


Exhibiting: The three-part CAFE tool, consisting of a survey, a time use tool, and the new chronicle app.

movisens GmbH

movisens develops solutions for researchers that need to capture data from participants engaged in everyday life activities. We combine expertise in the mobile monitoring of physiological signals and psychological data acquisition to provide research grade tools for ambulatory assessment.

Using innovative hardware and software, the movisens product line includes sensors that capture long term measurements of high resolution ECG, electrodermal activity, and physical activity data. Our data analysis software allows researchers to easily calculate secondary parameters from the raw sensor data with just a few clicks.

Intuitive and flexible, movisenXS sets the standard for Experience Sampling and intervention software. Whilst it’s possible to implement a complete suite of questionnaires with detailed sampling schemas, it also offers many passive data acquisition abilities, such as logging the activity of the participants on their device.

Though each system operates independently, the combination of sensors and experience sampling provides further insights in to the subjective psychological state of the participant from the experience sampling, coupled with the objective physiological state captured by the sensors.

To gain even deeper insights into participant behaviour, the sensors feature the ability to interact with the experience sampling platform, using changes in physiological states to trigger questionnaires or interventions.


Exhibiting:  A range of high fidelity physiological sensors, all featuring 3D accelerometer, 3D Gyroscope, Barometric air pressure sensor, and Proximal temperature sensor, and enhancements that enable the capture of ECG data, or EDA/GSR data, or Light detection. Data Analysis software allowing the extraction of secondary parameters from the physiological data captured by the sensors. An experience sampling app, capable of passive logging of device usage patterns, and also capable of experience sampling or interventions.’’

Good Vibrations is a generalizable mobile intervention that combines nudge theory and negative reinforcement to create a subtle, repeating phone vibration that nudges a user to reduce their digital overload. For example, if a user has a daily Facebook limit of 30 minutes but opens Facebook past this limit, the user’s phone will issue gentle vibrations every five seconds, but the vibration stops once the user navigates away from Facebook. This app successfully decreased daily digital consumption by over 20% in initial trials.
