Dave Vernier's History of Data Collection:
25 Years of Vernier Software & Technology
In honor of our 25th anniversary, I was invited to do a talk at the American Association of Physics Teachers on the history of the company. Getting ready for this talk led me to reminisce on how data collection has evolved over the years.
1980s
Game Port Interfacing with Apple II or IBM-Compatible (MS-DOS) Computers
In the 80s, if you wanted to collect data with a computer, you purchased our software and in the accompanying manual you found instructions on how to build your own sensors from parts that could be purchased at local electronics stores. You plugged sensors into a connector that was really meant for joysticks that were used in games. After a few years, we started selling parts, so you did not have to make trips to Radio Shack. In the late 80s, we started selling assembled sensors (made in our garage).
1990s
Data Collection with Macintosh and
Windows computers using ULI and MPLI.
In about 1990, we introduced two popular interfaces: the Universal Lab Interface (ULI) and the MultiPurpose Lab Interface (MPLI), along with software to run on both Macintosh and Windows computers. We continued to develop curricular materials for using data-collection technology in the classroom from middle school through introductory college science classes.
Serial Box Interface and Calculator-Based Lab (CBL)
The ULI and MPLI interfaces were fine for physics teachers, but chemistry and biology teachers did not need as many features and wanted a lower price, so we developed the Serial Box Interface. (That was my favorite product name of all time. Many people ordered a Cereal Box Interface.) In 1994, Texas Instruments introduced the Calculator-Based Laboratory (CBL™). We worked closely with them to develop compatible sensors and curriculum.
Early 21st Century
Data Collection with Vernier LabPro
In 2000, we introduced LabPro, our lab interface for use with computers, TI graphing calculators, and Palm handhelds. We also introduced more and more powerful versions of Logger Pro software, with new features such as support for balances, spectrometers, GPS devices, and ProScopes. The addition of movies, video synchronization with data, and video analysis have been major improvements.
2004 to Present
Data Collection with Direct USB Sensors and Wireless Sensors
In 2004, we introduced our "Go!" line of products, with the goals of lowering the cost of data collection with computers and providing a solution for elementary schools. Free data-collection software was included with the sensor. We also introduced our "Easy" line of products, which plug directly into the USB port of a Texas Instruments calculator, lowering the total cost of data collection with calculators.
Keeping up with the advancement of technology, in 2006 we added the Vernier Wireless Dynamics Sensor System, our first wireless sensor! We also introduced the Vernier Spectrometer, as well as the Vernier BlueView Transilluminator. Over the years, we have added a few new sensors every year, so that there are now more than 55.
It has been a fascinating 25 years. What will the next 25 years bring? Thanks to all of you for your support over the years.
