The program is rebuilted on the Android-28 platform.
Instead of the gravity type sensor, the program now primarily uses an accelerometer type sensor.
Appeal to the gravity sensor will occur only when the start of accelerometer sensor fails.
If the accuracy reported by the sensor turns out to be a multi-digit number, then only one low-order digit of this number will enter the voice message.
The program is designed by a blind developer for their own needs.
It helps the blind to navigate the terrain and to make long walks on any routes.
The program using the same intervals (8 seconds pronounces azimuth on which is focused the smartphone, as well as the latitude and longitude of its location.
Parameters latitude and longitude are two-digit numbers, sourced from the third and fourth decimal from the corresponding value in degrees.
The values of two digits is easy to remember, so after some training, the blind gets ability to recognise his approximate location.
Real training may be substituted by a preliminary extraction of the location's parameters from some databases.
You can use a separate voice recorder to aid in the memorization of the parameters of the reference points.
The use of the program does not require in motion no manual manipulation with the device, every moment hands remains free.
This eliminates the problems associated with the use of touchscreen devices in the winter season.
If random people will come to your aid, then your hands will be occupied, but the program will save your ability to control your location.
Perhaps the details of the program will be useful in the presence of the dog guide.
There is no need to hold the device in hand, it may lie in a pocket or be otherwise fastened near you.
Voice messages of the program are pronounced in the language set in the system settings of the smartphone.
Although the presented version of the program focused on Russian-speaking user, it with a certain inconvenience can be used internationally.
Digital options will be pronounced in your language and to the distortion or concealment of illustrative words you can be soft and polite.
To improve the accessibility of the program on the devices, which does not support Cyrillic lettering, some Latin characters are added to the labels of control buttons.
With the same purposes, texts of voice messages of the program are typed in Latin.
Attention!
On some devices compass Sensor may in an uncontrolled manner make jump into the idle state and start giving a completely wrong information.
Unfortunately, the unreliability of Android compass is extremely dangerous for the blind, especially in urban environments.
It is recommended to have an additional device in the reserve, possibly from other manufacturers with the built-in "compass" program.
The program allows manual self-test of the compass.
To test the compass, change the viewing direction of the smartphone by 90 degrees and check that it appropriately changes the value of the azimuth reported by the device's sensor.
For moving of the compass to a working state, you should rotate the device in your hands, changing its orientation in all possible directions.
Some, but not all devices clearly indicate that compass moved to a working state at this action.
