Lei Feng network: According to the author of this article Cheng Chenglong (micro-signal dcl_utopia), intelligent hardware startup company product dog, from the video giant company to play smart hardware company, continue product design work.
Dashboard recorders have quickly become the standard for cars, and many Internet companies have entered the market. The fierce competition has resulted in significant increases in their prices and experiences. The following are some of the recent reflections on the interaction of driving recorder hardware.
Driving recorder has a single and clear function, but the price is relatively large, with a small screen, with five physical buttons is the more mainstream (affordable) mode; the screen is generally only for display, does not support touch operation; 5 One of the buttons is responsible for switching the machine on and off and the screen is lit and extinguished, so the following discussion is only under the framework of four physical buttons.
Take the driving recorder of a certain internet company on the market as an example. The home page is as follows:
The top shows the recording status, Bluetooth, wifi, recording and battery status. Similar to the top status bar on existing mobile phones, the user is easier to understand;
The date, time and speed are displayed in the video preview as a watermark, maintaining the same effect as when the video is played.
The lower four buttons correspond to four functions. The functions are displayed on the screen. Although this method is quite different from the smart phone operation (the text on the smart phone is the click position), it is similar to the function machine and the remote control in the living. Easy to understand quickly, almost no learning difficulty;
The user triggers the recording button to control whether or not the surrounding ambient sound is recorded when the video is recorded, triggers the album key to enter the video and photo entry, and triggers the setting button to enter the list of the drive recorder setting items.
When the emergency button is pressed, the annotations of the bottom four buttons all disappear and the recording progress of the emergency video is displayed, because the emergency video recording is the video of 10S before the pressing time and 50S after the pressing time, in order to increase the processing efficiency during this period. The machine does not accept other instructions. It also gives a full representation on the UI, as shown in the following figure:
After entering the album page, the operation definition of the four buttons has changed, as shown in the following figure:
On the cycle video and emergency video list pages, the buttons are defined as follows:
In the video play page, the key definition is as follows, and the photo preview page is similar to this without much description.
Next is the first-level page that is set up. The first-level page includes two forms. One is to select the current page, such as the video distortion correction switch; the other is to enter the second page, such as the video resolution setting.
The set of two pages is divided into three categories: display class (such as wifi information, support scan code login), select class (such as video resolution), detailed settings (such as machine time settings), the following three maps:
The above basic can cover all the operation modes of the driving recorder, then the problem comes:
1. What subtraction does the existing program do?
2. Is there room for further subtraction?
Subtraction of existing schemes:
Cancel recording open the key: line car recorder most important job is uninterrupted recording, if the increase key, it is possible to forget the user closes the open, so it will stay hidden to the accident; that someone have to ask, that if do not want to Let someone see where I am going, would I risk taking? It's very simple. Unplug the cigarette lighter directly.
Cancel the camera button: If the camera button is on, one of the four buttons needs to be occupied, then the recording button is most likely to be replaced, and then the recorded switch is placed in the setting, but this has a problem: emergency video and Taking these two actions will increase the user's ability to touch the driving recorder, especially taking photos? If so, will the risk of traffic increase significantly? I feel it will, so delete it. At the same time, from the perspective of commercialization, support for Bluetooth camera, and then buy an accessory, commercial leasing will increase by 10% (I think this is more to explain the problem).
Further subtraction:
Cancel the setting, set the entrance to wifi switch, as shown below:
Wifi page to increase wifi switch button, close the password and the two-dimensional code can be hidden, the picture below is the wifi open state.
Can you remember how high the frequency of settings on the phone is? Is android's dropdown and ios's use more frequent? However, because it is not a touch screen here, it cannot increase the pull-down operation. However, since it is a low frequency, why do we not set it with a mobile phone APP?
To do this, you need to add a pre-step - the driving recorder needs APP activation. Because it is necessary to link the APP to adjust the time when the driving recorder is used for the first time, at the same time, let the user set the recording parameters.
So why not just put the video and photo entry on the phone? The author believes that if an emergency occurs, the user needs to take out the mobile link recorder to be able to view. In such an anxious situation, these operations are not very good.
This has an advantage: increase the amount of APP installed, increase the space for follow-up push and operation, and even push some driving recorders at the beginning of the installation, such as "the first phase of driving recorder field game -" The DVR's emergency video recording of scoring goals) allows users to be attracted to their content, and obviously feels that there is a second period, then the APP will not be immediately deleted.
This is a double benefit, why not?
