The first thing to mention is the location design of the volume button and the power button, which is intelligent in the market at present.Mobile phoneEither the volume button is on the same side as the power button, or the power button is on the right side of the phone and the volume button is on the left side. Anyway, the power button must be on the right side of the phone. The same side and different side of the two design naturally can not say who is good or bad, but this is not convenient for left-handed people, because left-handed grip touch the right power button becomes very "awkward".
In fact, in the era of functional computers, power keys have not yet been born, all mobile phone front are entity keys, until the arrival of small-screen smart phones can be applied, power keys are placed in the middle of the top of the fuselage, easy to operate, such as HTC mobile phones will continue this design for a long time. But as the screen body grows larger, the top power button design is no longer convenient for right-handed or right-handed people.
Next, let's look at the fingerprint recognition function of mobile phones. At present, there are two popular recognition methods on the market: screen fingerprint recognition and side fingerprint recognition. Screen fingerprint recognition has been common. With the increase of mobile phone screen, power keys gradually shift to the right side of the fuselage. Nowadays, mobile phones using side fingerprint recognition usually integrate the side fingerprint identifier with power keys. Only when the mobile phone is held in one hand can it be unlocked. This is also very unfriendly for left-handed people. Well.
Taken together, the design of volume keys and fingerprint keys still needs to go through the test of time, in order to be more in line with the ergonomic experience, how to meet the daily needs of left-handed people? In the future, the relevant design still has a long way to go.
