Welcome

Over the last 30 years, digital screens have become an inseparable part of our lives. Statistics show that people are using digital screens around 12-16 hours per day. But looking at digital screens for an extended period of time is problematic both for the human eyes and posture. The health problems associated with improper use of digital screens are eye dryness, redness, myopia, headaches, neckache, backache, potbelly, etc.

There are certain rules which computer users should follow to avoid/decrease the unhealthy impact of computer use (such as blinking a minimum of 15 times per minute, keeping min 35-40 cm distance from the screens, sit in a correct way). But most of us (80-90 %) don’t know/forget about it. Here is what a correct sitting position looks like:

 

Our mission in Bliink is to solve this problem. Blink is able to calculate your blinking rate, check your sitting position, and measure the distance from the camera. Bliink also provides the historical performance for both blinks, posture, and distance!

Now, let’s explore how it works.

How to download and install Bliink?

 

 

How to use

1. Main window

The user can also see the status of the app (left sidebar).  If the app is a trial version, the status is Trial and below the expiration date is shown.

Once the user buys a subscription, using Activate button, the status will change to active. From this tab, the user can get the link to the user's guide.

2. Records

Under the Record tab, users can check their historical performance both for blinking, posture, and distance.  Bliink enables users to see their historical performance during the whole day. Users can see the daily average performance, as well as the average performance on a selected range of dates.

                                   

Using Bliink for a few weeks, users can notice the progress in their healthy working habits development. With the Records tab, users can also analyze at which hour of the day the performance was not healthy. If the performance is more than 90 %, it means that 9 times out of 10 checks users’ behavior was healthy (more than 15 blinks per minute, 35 cm distance from the screen, and correct sitting position). By selecting the dates user can check the average performance over the given period. By using Bliink for several months, users can notice an increase in their healthy working habits. 

 

3. Settings

There are 3 main components inside the Settings tab: General, Blinking, Distance &Posture.

3.1. General

The following options are available:

  • Blink Min Value: minimum number of blinks in one minute as limit

Based on the research, for a healthy eye minimum of 17 blinks are necessary per minute. If you will not blink 17 times per minute, then our app will notify you. You can increase or decrease this value, based on your preferences.

  • Blink Criteria: this number is used for the eye blink detection algorithm

Dependent on the user's eye, this number should be adjusted. If you notice (using records), that the app is underestimating the blinking rate, then you need to increase this number, and in the case of overestimating: this number should be decreased.

  • Distance Limit: this number is used in the distance detection algorithm

Dependent on the position of the camera, this number should be adjusted. The best recommendation is to keep at least 35 cm distance from the digital screens. After sitting in the correct way, the user can use Adjust button to find the corresponding criteria and then apply them to this field.

  • Posture Limit: this number is used in the posture detection algorithm

Dependent on the position of the camera, this number should be adjusted. After sitting in the correct way, the user can use Adjust button to find the corresponding criteria and then apply them to this field.

In order to adjust the above-mentioned criteria, the user should use Adjust button. After clicking on this button, within a few seconds, the frame will be opened.  The user should sit in the correct position and distance (mentioned in the beginning), and press or Exit. Then by pressing Q/Exit the frame will disappear and the corresponding criterion will be modified. The user should click on the Save button, so the changes are saved.
If the user notices, that the blinking part is not working correctly, they need to increase/decrease the Blink Criteria. If blinking notifications are not disappearing, then the user should decrease the criteria, otherwise: increase.

                                   

 

3.2. Blinking

This tab is making configurations for the blinking part. The following options are available:

  • Period: the duration of the webcam for a single checking
  • Frequency: number of checking times

For example, if the user selects 10 seconds for the period and 12 times per hour, for the frequency, Bliink will open the webcam 12 times within  an hour (once in 5 minutes, and each time, the camera will be opened for 10 seconds). We recommend users to start with higher frequency and large periods and decrease them over time, once healthy working habits are built.

  • Notification size: the size of the notification to appear on the screen

Currently, there are 3 options for notification size: small, medium, and big.

  • Notification Position: the place of notification gif on the screen.

There are 5 options for choosing the notification position: center, top left, top right, bottom left, and bottom right.

  • Notification Type: type of the notification gifs

Currently, Bliink has 2 gifs to notify users: human and human-owl combined.

After making the changes, click on Save button to keep the changes. If you want to go back to the default settings, click on Reset button.

3.3. Distance and posture

This tab is making configurations for posture and distance parts. The following options are available:

  • Frequency: the number of checking times.

For example, 12 times per hour, for the frequency, Bliink will check the posture and the distance 12 times within an hour (once in 5 minutes). Notice, that there is no Period parameter in this part, as Bliink uses a single capture for the detection. We recommend users start with a higher frequency, and decrease them over time, once healthy working habits are built.

  • Notification size: Size of notification to appear on the screen

Currently, there are 3 options for notification size: small, medium, and big.

  • Notification Position: Place of notification gif on the screen

There are 5 options for choosing the notification position: center, top left, top right, bottom left, and bottom right.

  • Notification Type: type of notification gifs

Currently, Bliink has 2 gifs to notify users: human and human-owl combined.

After making the changes, click on the Save button to keep the changes. If you want to go back to the default settings, click on the Reset button.
