Users Guide

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.

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.

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.

• 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

• 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.

• 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.

• 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: Number of checking times
• 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.

• 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.
