When the hard and yellow corn kernels reach a high temperature around 180°C, the pressure inside increases to 930 kPa (about 9.2 mb), and it will eventually pop, causing the protein and starch that were boiling inside to rise as bubbles. The bubbles quickly solidify and become white popcorn. A brain that only responds to intense stimuli like popcorn is called the popcorn brain. If you can't stand a moment not looking at your smartphone while waiting for a bus and going up and down the stairs in the subway and if you put off the work you have to do and keep unlocking your smartphone screen for something new, then you are a popcorn brain. David Levy, a professor at the University of Washington, who introduced the term “popcorn brain” to the public, said, "The brain loses interest in simple and mediocre things when it continues to receive strong stimulations." This is why smombies who can’t let go their smartphone, looking for strong stimuli, can’t be considered separately from the popcorn brain.

‘Forest’ – If you plant a seed in the forest when you need to concentrate on something, the tree will grow when you concentrate, and if you leave the app, not being able to stand the temptation of the smartphone, the tree will dry out. The app will help you stay away from the smartphone for a while to increase your concentration while planting trees.
‘Focusi’ – This is a study timer. Before starting something that you want to study or concentrate on, check the tips on how to concentrate and prevent smartphone addiction on the ‘Hint’ screen to motivate yourself. This is an app that motivates you while providing statistics on the time of concentration in the past.

'Popularization of AR Glass'
Various smart devices have been released for those who are often called smombies or phono sapiens. One of them is AR Glass, which became more affordable and lighter since August of this year. By improving the previous version, which could not be broadly commercialized in terms of price and size, or, to put it simply, too expensive and heavy, the domestic communication carrier, LG U+, began to sell the public-oriented AR Glasses that are 1/4 of previous AR glasses in terms of price and weight. It is expected to prevent the risks of smombies who might bump into passers-by while looking at the smartphone while using public transportation or on the street as you can increase the screen up to 100 inches and check the situation in the front of you.
'Order and Payment Kiosks and Barista Robots'
The non-face-to-face culture has more widespread due to COVID-19. However, it has already been spreading among those who are in their 20s and the emergence of smombies can be taken as a part of the culture. In the university town, kiosks that are used to place orders and make payments in unattended stores are not new, and there are even unattended cafes and barista robots. In this cafe, which can be operated unattended around the clock, you place your order through the Kiosk and an AI robot will prepare Americano and other beverages. It is expected that this kind of service is going to expand gradually as it targets millennials who are familiar with smartphones.

Nevertheless, a culture against smombies is also emerging. A movement called digital fasting or digital detox is expanding recently. Like no mobile-phone phobia, it is an essential practice for modern people who suffer from anxiety symptoms when they do not have their smartphones and are overly dependent on them. The movement is about setting their own rules to lower their smartphone dependency, such as turning off smartphones outside of certain hours or consciously reading paper books before going to sleep instead of taking their smartphones. When have you been spaced out recently? If you have not been spaced out today, you might be a smombie. You need self-awakening and self-awareness to pull yourself out from the smombies. When you rely on new information and more stimuli, you will have less ability to remember realistic information and interpret complex texts. Mark Bauerlein, a professor at Emory University in the U.S., also indicated a social problem in his book, , that the phono sapiens are digitally bound together but unable to develop in terms of communication and interpretation.
Emergence of Travel Packages
In the US, a travel package called Getaway House is popular. Getaway House provides a space to spend time in the woods away from digital devices such as mobile phones, laptops, and TVs. In Korea, a resort, disconnected from external network, was constructed in Hongcheon, Gangwon-do.
