Visual Environment Evaluation Tool
Introducing Project VEET, from Meta Reality Labs Research. A state-of-the-art instrument that logs quantitative light data without cameras, microphones, or cloud connectivity.
*shown installed on a typical pair of prescription frames.
What is the VEET?
The Visual Environment Evaluation Tool (VEET) is a research instrument that integrates the highest quality of spectral, luminance, movement, and distance sensors into an all-day-wearable form factor that can be connected to any existing glasses frame.
The VEET is a general purpose device that can be used to collect data to understand a user’s visual environment with applications in perceptual science research such as gaming, entertainment, or health-related research. One potential application is research into how the modern visual diet influences the onset and progression of myopia.
Privacy
The VEET has no camera, no microphone, no bluetooth or wifi connectivity, and does not record any personally identifying information. The device gathers data without compromising the wearer’s privacy or comfort.
Sensor Suite
At sensing rates of up to two seconds (1/2 hz), the VEET gathers the following information through four robust solid state sensors.
Luminance
Ambient Light Sensor
(ALS)
0.1-100,00 lux
Flicker Detection
Spectrum
Spectral Sensor
(PHO)
11 wavelength bands
350-1000nm
Distance
Time of Flight Sensor
(TOF)
8×8 samples
45-degree frustrum
Activity
Inertial Measurement Unit
(IMU)
6-DOF IMU
Easy to wear
The VEET is compatible with a range of commercially available eyeglasses frames, accommodating both clear and prescription lenses. The participant wears the device during the day, charges each temple arm on wall power at night, and returns the device to the researcher when the study is complete.
Continuously logs data
Each VEET temple arm comes with a battery that supports all-day data logging. If charged daily, the VEET has a data storage capacity of more than one year.
Data is continuously logged at pre-configured rates whenever battery reserves are available or the device is charging on wall power.
Researcher friendly
Easy to configure
The VEETManager software provides a graphical user interface for configuring the data logging intervals and previewing sensor data. The software is compatible with both Windows and MacOS.
Easy to access data
The VEET connects via USB-C and shows up as a simple disk drive. The data is recorded as time series data in a CSV file.
