Will you keep it or delete it?

Do you ever check how many photos or apps you have on your phone? Have you ever considered managing your personal data?

If you answered “No” to any of these questions, you might want to rethink about your personal data storage. Most users usually do not keep track of the data on their devices until they are notified that they are running out of storage.

Personal data can be social media accounts, favourite playlists, and even credit card details. You might be surprised to find out how much personal data is shared across devices and online platforms.

It is important to “derive value from your personal data over time,” says Dr. Francesco Vitale, a PhD candidate in Human-Computer Interaction at the University of British Columbia. The process of selecting what to keep and delete could be difficult for users because of their attachment to data. If that is the case, is there any kind of technology that can help facilitate data management?

This is exactly what Dr. Vitale questioned and studied. He used a Research through Design approach to come up with the five new design concepts to analyze people’s opinions towards different approaches of keeping and discarding personal data.

Design Concepts

Patina – a visualization of how frequent the users access the data.

The age of data is shown by using a spiral. A longer spiral means more frequently accessed data.

Data Recommender – a system that tells users which data needs attention. 

This system is partly incorporated into apps like Google Photos and Files on Android.

Temporary Folder and Temporary App –  both with features that have an “expiration date.” 

Users can decide how long they want to keep certain folders/apps for, and it will be uninstalled automatically.

Future Filters – an app that allows the users to decide what to do with data in the future. 

The users are given choices from a set of actions and criteria in order to decide what happens to the data.

Impact in Our Lives

The result of the study showed that opinions on managing data vary between not trusting technology vs. being open-minded about technology managing their data for them. 

Some have mentioned that they do not mind deleting their data off their devices for example, in the case of social media it is “never truly deleted, … there will always be a copy somewhere out there.” Many users store their personal data on online platforms without thinking about the consequences.

Recently, Dr. Vitale participated in a short interview that discusses his research and about how data management affects his life.

To further discuss the topic, Science 300 podcasters at UBC decided to cover Dr. Vitale’s research and see how data management affects the lives of students.

With different views on the topic, perhaps data management is a subject that should be taken more seriously and further investigated.

Increased screen time can lead to deficient brain development in children

Have you ever seen a tablet or phone given to a child as a solution periods of crying or whining? Giving an infant a portable device is an easy and harmless remedy to infant tantrums right?

Not exactly, a recent study published by JAMA pediatrics reveals that an increased amount of screen-based media use can lead to lower language retention and literacy skills in prekindergarten children.

Researchers studied 69 children from ages 3-5, to determine a possible existing relationship between screen-based media use and brain development. From their study, they were able to conclude that children with an increased screen time, compared to the guidelines of the American Academy of Pediatrics (AAP), showcased a lower microstructural organization and myelination of white matter tracts that support language and literacy skills.

Myelination of white matter tracts is crucial to the cognitive development of infants as it involves the formation of a myelin sheath around a nerve to allow the a quicker displacement of nerve impulses in the brain.

From their research, lower amount of white matter in childrens’ brains lead to a decreased level of derivation of meaning of objects, symbols, and letters, which scientists believe plays a crucial role in literacy development.

To develop these conclusions, scientists analyzed the results of a ScreenQ survey (completed by the child’s parents), which is based off of four main factors of the AAP guidelines involving the child’s access to screen, their frequency of use, the content viewed, and interactivity or co-viewing. From the survey, the researchers compared the survey results to MRI scans of the the children’s brains and also to results from a series of communication tests designed for children with developing literacy skills.

The solution to these neurobiological risks in children may be very tricky as screen-based devices can be found in almost every household and are used daily by the general public. However, a way to prevent deficiencies in child brain development can be to follow the guidelines proposed by the AAP. Some of the recommendations are:

  • For toddlers younger than 18-24 months, avoid any form of media other than video chatting
  • For children ages 18-24 months, only allow children to watch media with parents (co-viewing) to begin communication development though watching and talking with parents
  • For children ages 2-5, allow only 1 hour a day of media exposure (educational programming) through co-viewing if possible.
