Davis instruments 6250 vantage is a head-mounted device that can be used for a number of functions, including making measurements about the motion of people and objects, as well as measuring distances. The 6250 can be connected to a PC or laptop with a simple USB interface and has Bluetooth wireless capabilities, so it is compatible with wireless hand-held devices. The device is also capable of displaying information such as text and graphs in real time. It was designed to work with Windows 7 or higher operating systems.
Features of davis instruments 6250 vantage
- A large field of view (3.7 degrees)
This allows a person to see an entire room at once. The measurement is shown on a digital display mounted on the head unit. It also allows the instructor or professor to walk around a lab while still being able to see what is going on in the room.
- Head tracking and positioning data
This function allows for orientation and movement to be recorded. This data can then be used by computer software applications that run on PC’s, including 3D Simulations, game programs, and image analysis software. With the head tracking feature, the research department for one company was able to track locomotion of animals in their observation chambers with very high accuracy.
- Camera and laser positioning
Cameras are mounted onto the unit (three cameras total), and two lasers are placed in the room, horizontally and vertically. This allows for the software to track visual images of an object or animal, as well as its 3D position in real-time. This data can be used to monitor the movement of an animal’s head or body, as well as its eye movements. The lasers can be attached to different objects in order to measure distances between them. The device can also be calibrated with a magnetic compass, which is useful for determining an object’s position with respect to magnetic north.
- Eye tracking features
This allows for eye movement and gaze position to be monitored in real-time using the device’s camera. With this feature, it is possible to monitor eye movements both independently and in conjunction with head movement or animal body position data. This information can be used for psychological research as well as marketing research. The visual data can also be used for image analysis studies, such as facial recognition or motion tracking of sports players movements on a field.
- Recording of data
The device can be set up to retrieve recorded data at any point in time, based on the user’s preference. This allows for video recordings, audio recordings, or even customized data collection with the use of scripts and programming. The device is capable of storing 3 hours worth of data before it needs to be uploaded to a computer. If iPods are attached to the head unit, it is possible for a lot more recording time to be available. The information being recorded can also be saved as a .csv file and imported into Microsoft Excel or other spreadsheet programs. This allows for codified analysis of research outcomes as well as real-time plots that are available after an experiment has finished.
