An Alternative Approach to Data Acquisition Using Keyboard Emulation Technique

چکیده
A number of data acquisition systems depend on human interface to access computer for measuring, processing and analyzing data and to prepare it for presentation and storage. Data acquisition software is installed on the computer and all intended operations are performed manually. The data acquisition software requires user intervention for operations like selection of measurement setup, acquisition and storage of data to computer. The duty of users becomes laborious if the data acquisition process lasts for a long duration and requires continuous repetition of steps. An appropriate solution to overcome such problem is to replace the physical operator with a virtual user. This software generated simulated user sits at the data acquisition process through out and automate all the intended steps of data acquisition. This paper presents a new approach for data acquisition by using keyboard emulation technique. A keyboard emulation software is developed which runs beside the main data acquisition software and acts as a virtual user. All the operations which require user interface are performed through fully automated computer program. The developed software/system is executed in a real time environment and the functionality of the software is verified. In the end, potential application areas of the designed keyboard emulation software are explored.

Using Arduino microcontroller boards to measure response latencies.
Latencies of buttonpresses are a staple of cognitive science paradigms. Often keyboards are employed to collect buttonpresses, but their imprecision and variability decreases test power and increases the risk of false positives. Response boxes and data acquisition cards are precise, but expensive and inflexible, alternatives. We propose using open-source Arduino microcontroller boards as an ine...
