Designed for cognitive and perception tasks that require millisecond precision. Powerful and easy to use.
Do you have tasks in which you measure RTs that average less than 1000ms? Do you have tasks in which stimulus onset and presentation times are seriously expressed in milliseconds and not seconds? Are you comfortable with the “blocks of trials” concept? If so, then you have come to the right place - Direct RT can dramatically simplify your life.
DirectRT designed for cognitive and perception tasks that require millisecond precision. Powerful and easy to use. With Direct RT you can quickly and easily create reaction time tasks that require precision timing. You will be able to easily obtain accurate high speed response and input from keyboards, mice, joysticks, microphones and external hardware. Present sound, video, images and text with exacting precision. You will be amazed at how DirectRT can make this so easy.
DirectRT comes with extensive on-line help files and a manual, and an on-line tutorial with over 40 samples that illustrate simple and advanced techniques.
DirectIN response systems are designed for use with DirectRT or MediaLab, and can be used with other software too.
Offering researchers an easy-to-configure, durable and user-friendly method of collecting data using their software of choice. The system is based on a high-performance microcontroller which communicates with the host computer via USB.
Because the average timing latency and error of the DirectIN electronics is well under a millisecond, it is ideally suited for precision response time measurement. The box is is also ideally suited for even the most physically demanding experimental environments.
The box works with any operating system that can accept a standard USB connection and appears to be a standard (albeit extremely precise) QWERTY keyboard when connected to any computer running DirectRT or MediaLab. Any button of the hardware system can be easily programmed to appear as any key on a standard keyboard.
The base unit contains the control electronics for the system, as well as a connector which mates with the wiring harness attached to a top which can be changed at a moment's notice. You can make the change in under two minutes.
Additional custom-designed tops can be specifed with a template
DirectIN precision keyboard
A modified high quality keyboard (from Apple) with a circuit board and chip that can be used to scan and report keyboard activity with almost no delay (~900 microseconds). This provides the convenience of a standard keyboard with the speed and accuracy of a custom-made button box.
The upgraded keyboard will appear as a standard keyboard when connected to any computer (PC or Mac) via USB or USB2.
It is strongly recommended that systems running DirectRT have at least 128mb of memory, a graphics card with at least 8mb of video memory and a processor speed of at least 500mhz. The log files that DirectRT produces will show you whether or not any computer in question can handle your experimental design.
DirectRT requires that Microsoft’s DirectX Version 7 or later be installed (Windows ME, 2000, or XP you will already have DirectX Version 7 or later installed). Windows NT4 Does not support DirectX.
Finally, it is also necessary to have a spreadsheet application installed (e.g., Excel) if you plan to edit or view the DirectRT input and output files on that machine-or if you plan to try the DirectRT on-line tutorials. All input and output files are created and saved in .CSV format which is editable from any standard spreadsheet application.
