H-ITT Announces New Faster Base Unit and Software!

New H-ITT Hardware and Software Reduces the Occurrence of False Positives.

Wednesday June 14, 2006: Hyper-Interactive Teaching Technology (H-ITT), a leader in hand-held remote technology for the classroom, is now offering a new, faster base unit and software version that reduce the possibility of students experiencing "false positives."

A false positive occurs when a student remote displays a green light without the response being recorded by the computer. This can occur in H-ITT's previous two-way system if a student responds to a question before or after the instructor presses the start or stop buttons in the software, respectively. The new software has an option to put the base units to "sleep" between questions so the remotes cannot display a green light prior to the instructor pressing the start button. In addition, the new base units have an adjustable baud rate setting which allows them to run at speeds up to 115.5 Kbps, about 5 times faster than the previous base units. This feature provides for faster response collection.

These new base units are fully backward compatible with existing base units, remotes, and software. However, the sleep function and the faster baud rates are only available when running the new 1.9 version of the H-ITT software.

The new software also offers the ability to change the font size of the text while displaying questions, as well as the ability to save the ID box display and histogram as a bitmap in PNG, TIFF, or JPG format. As always, the H-ITT software runs on Windows, Mac, Linux

The key advantages of the new adjustable baud rate USB base units are:

  • Fully backward compatible with old two-way USB models and old software versions.
  • Higher baud rates for faster response collection in the classroom.
  • Ability to be put to sleep so remotes do not get green light when a button is pressed.
  • For experts, base units have internal jumpers that allow separate disconnection of USB power and power to CAT 5 cables for large room installations.

The key new features of version 1.9 of the H-ITT software are:

  • Fully backward compatible with all base units and remotes.
  • Ability to run at faster baud rates with new base units for faster response collection in the classroom.
  • Ability to put the new base units to sleep so remotes do not get green light when a button is pressed.
  • Ability to change the font size of the text while displaying questions
  • Ability to save the ID box display and histogram as a bitmap in PNG, TIFF or JPG format.
  • As always, runs on Windows, Mac, Linux.

H-ITT develops their software using C++ and the popular open-source wxWidgets (www.wxWidgets.org) C++ library. This library allows H-ITT's software development team to target multiple platforms from one code base. In addition, utilizing wxWidgets allows the applications to have the native look-and-feel of their respective operating systems.
