Still chasing the big screen? How big a hand to play the big screen smartphone

Last September, Apple finally gave up the idea of a small-cell phone that it had been insisting on for years, and started to cater to the public's needs and launched two of similar tablet-like iphones, according to foreign media reports. However, as the mobile phone becomes larger, the screen of the mobile phone is becoming more and more difficult to "grasp", especially in the time of one-handed operation ...

To understand the average size of the palms and the suitability of the handset, the experts Exchange Web designer has created a set of images that reveal the "natural" and "inaccessible" areas of Apple and Samsung's 4 best-selling mobile phone screens.

The four phones are Apple's iphone 6 and iphone 6 Plus, and Samsung's Galaxy S5 and Galaxy Note 4. The images are made by technical professionals at the experts Exchange website, and the website says: "Smartphones are getting bigger, but our hands aren't getting bigger." Have you ever wondered how big a single hand would be to touch the entire screen easily? We performed some calculations on the iphone 6, iphone 6 Plus, Samsung Galaxy S5 and Galaxy Note 4, and then compared them to several athletes. "This image was produced by technical professionals at the Xperts Exchange website, comparing the average palm parameters of men and women, including athletes like LeBron James and the" Illinois State Giants "Robert Vadero.

According to the picture, the average height of the female is 1.6 m, the palm length is 17.1 cm, the width is 7.3 cm, the male's average height is 1.75 meters, the palm length is 18.8 centimeters, the width is 8.3 centimeters. Apple's iphone 6 has a 12-centimeter screen, Samsung Galaxy S5 screen is 13 cm, Apple iphone 6 Plus is 14 cm, and the biggest is Samsung Galaxy Note 4, 14.5 cm.

Retired basketball star Shaquille, for example, can easily use the IPhone 6 and Galaxy S5 in one hand, but Michael Jordan is a bit less handy when it comes to S5. Even 2.03-meter LeBron James cannot easily and cheerfully use the two flagship handsets of Apple and Samsung.

The only one that can easily use the IPhone 6 Plus and Galaxy Note 4 is Robert Vadero (Robert wadlow) – also known as the "Illinois State giant". Vadero height of 2.72 meters, died in 1940, is the modern human society recorded the highest people. Samsung's Galaxy S5 mobile phone screen is a 13-centimetre green area in the "natural state" of the thumb-touch area, yellow for "accessible" areas, and red is "untouchable" areas. The data used for male and female average palm parameters the iphone 6 Plus screen for the 14 cm Galaxy Note 4 screen for 14.5 cm picture display, to single hand using the iphone 6, the user's palms need to be 24.3 centimeters long, 11.7 centimeters wide. For the iphone 6 Plus (left) and Galaxy Note 4 (right), these two parameters need to be increased to 29 cm and 14 cm. Using this data, the image shows the touch area of the thumb in the "natural state" of the sexes. The Apple iphone 6 phone screen is 12 centimeters green area in the "natural state" of the thumb touch area, yellow as "accessible" area, and Red is "untouchable" area

The picture shows that to use the IPhone 6 in one hand, the user's palm needs to be 24.3 centimeters long and 11.7 centimeters wide. For the IPhone 6 Plus and Galaxy Note 4, these two parameters need to be increased to 29 cm and 14 cm. Using this data, the image shows the touch area of the thumb in the "natural state" of the sexes, which is green. Yellow is a "palpable" area, and red is an area that the thumb cannot easily touch.

Apple is aware of the problem, and has introduced an accessible feature on the IPhone 6 and 6 Plus, which is to use the thumb on the touch ID to place the application icon close to the bottom of the screen to make it easier for the thumb to operate. A Japanese company has also developed an extension tool for use on the thumb, which allows users to easily operate a large-screen phone with one hand.

The company, known as Thanko, is located in Tokyo and its products are called Yubinobiiru (Japanese for "finger growth"), with a retail price of $13.63. This "finger-growth device" is made of silica gel, weighing 11 grams, inside the hollow, can reach the thumb or other fingers. At its top is a small black conductor, which ensures that the touchscreen phone recognizes its touch signal.

By wearing the "finger growth device", most people can fully touch the entire mobile screen with one hand. A December 2014 study shows that smartphones are fully integrated into modern life and may even change the shape and function of the human brain.

The scientists found that people who use touch-screen phones every day have a larger, more powerful somatosensory cortex, located in the center of the brain, which controls thumb activity. Researchers speculate that the more time a smartphone is used, the stronger the link between the brain and the hand. Dr. Arko Ghosh, a neuroscientist, says our addiction to smartphones shows the human brain's ability to adapt to changes in the environment.
