When people are playing video games,programming,reading and watching videos by computer,cell phone and tablet,they blink eyes about 3 times or less per minute.People blink about 10-15 or more times per minute in normal time.If people haven’t blinked for a long time,eyes will be dry and tired.

Our system aims at to keep PC users' eyes healthy. It is good to apply our system when user need to focus at screen for a long time.User can apply any place if the room light can interact with our system.

Since the video game market may be monopolized by the VR device in the future,our system may provides good function for the VR device to keep users' eyes healthy.

Our system comes with the HotPotato(a portable vibrator),users can put the HotPotato to anywhere they like,such as under the chair,sofa,bed…...

Our system will provides the main function to force users to blink if they haven’t blinked for a configurable time by turning on the HotPotato to keep their eyes wet with not distracting too much users’ attention from the screen and not causing much scare. The system may provides other sub-function to keep users’ eyes healthy:low ambient light warning,system will adjust the light automatically,long computer using time warning.

The system may collects data from the software and arranges data to back feed to users.

















The system will detect user's eyes state(close or open),PC running time and meter the ambient light.



The system will calculate how long the user hasn't blinked,PC running time threshold,also calculate the suitable ambient light for user.



The system will turn on the HotPotato.The system will also jump out the warning window when PC have runned for a long time, adjust the brightness of the room.



User only blink,the HotPotato will turn off.


Features Description
Sensitive It gathers informations about the blink rate of PC users' eyes, ambient light level in the PC used space and the PC running time. These information is exploited to have warning by HotPotato.
Responsive It control the HotPotato and the warning window to remind PC users to blink eyes. It also monitors the lighting of the building in order to improve the PC using environment for users' eyes.
Adaptive The system observes past data and evolves accordingly.
Transparent The user intuitively exploits the software by the warning of window or HotPotato. At the same time exploits the software without being aware of the automatically lighting control behind it.
Ubiquitous Any PC users can benefit from the system by using the software


1 Purpose and scope

When people are playing video games, programming, reading and watching videos by computer, cell phone and tablet, they blink eyes about 3 times or less per minute. People blink about 10-15 or more times per minute in normal time. If people haven’t blinked for a long time, eyes will be dry and tired.

Our system aims at to keep PC users' eyes healthy. It is good to apply our system when user needs to focus at screen for a long time. The user can apply our system to the room where he works with the PC.

Our system is composed of two parts, the software installed in the PC, a portable vibrating device and the light in a certain room. The software works with the camera of the PC by detecting the movement of user’s eyes. It is related to face recognition. The camera catches the user’s face and the software can detect how many times the user’s eyes blink in one minute. If the amount is less than 10, the screen will be fuzzed up and force the user to blink. What’s more, the vibrator will be placed beside the user like on the desk or on the chair, and it will vibrate to remind the user to blink. The user will need to press the vibrator to make it stop.

This way turns out to be mild and effective after experiments.

In addition, the system has the function of adjusting ambient light. With the camera, the software can detect the brightness of environment and help the user to adjust the ambient light to a comfortable level. The system can also show warning after long computer using time.

Finally, the system may collect data from the software and make a data report to feed back to user.

3 System Requirements

3.1 Functional Requirements

Functional Area Description
INST installation
NOTIF notification sent by the system to user devices
PREF interface for setting user preferences

FR INST.1: Software Installation

· Description: The system works with the software installed on the PC with camera. So the software is to be installed on laptop or Desktop computer with camera. The operating system should be Windows 10 or below Windows 10.

· Priority: 1

FR INST.2: Hardware Installation

· Description: The system works with the vibrating device. The device should be installed on the desk near the computer, or on the chair. The user can install the device by simply putting it on the desk or attaching it to the chair.

· Priority: 2

FR INST.3: Camera Installation

· Description: The software detects the action of eyes with the help of camera. So the computer needs to be installed with camera. The laptop is equipped with camera but the desktop computer sometimes doesn’t have camera, so an extra camera needs to be installed and linked to the computer.

· Priority: 1

FR NOTIF.1: Notification of the software

· Description: The software creates notifications by fuzzing up the screen and force the user to blink his/her eyes. After the user blink eyes, the screen will turn back to normal.
