Hi pavelfatin
i had downloaded & install java and typometer. but not able to use it and i did not find any other notes which explains how to use typometer.Can you please guide me about its uses.

Thanks

To start the application simply run typometer.jar via a double click, alternatively, you can run java -jar typometer.jar from the command line.

The "Usage" section of the Typometer description explains the principles and the steps fairly well.

There are also a few practical tips on how to use Typometer posted as a comment to the main technical article.

Hi Pavalfatin
i am able to launch the application by simply running Typometer.jar file.I went through Typometer description but one thing i did not understood is what kind of file(.txt, .xls, .doc or .csv format) i should use for testing purpose.because i am trying to open the excel sheet and other format for benchmarking but it does not start.
i can see some screenshot but that is about after benchmark is completed.i am working on keyboard for which i need to measure latency of key press.Since u have have done alot of work on this,so can u please guide me.Will be waiting for your reply.

Thanks & Regards

There's no need to load any files before starting the benchmark (the option to open a file is intended only for importing of previously exported results).

Typometer doesn't rely on physical keyboard - it inserts characters automatically and measures delays between the emulated keystrokes and the appearance of new symbols on a screen.

To perform the benchmark, one needs to:

• open a text editor (e.g. Notepad),
• open Typometer application,
• start a benchmark in the Typometer,
• transfer OS focus to the editor (activate the editor window),
• wait for the benchmarking to complete.

Hi pavelfatin
Thanks pavalfatin for quick reply.i am able to run benchmark as you mentioned in the description.But it doe not serve my purpose.i wanted to measure the latency of the keyboard.i mean when we press the key,how many milliseconds it takes to appear on display.
But your application do it automatically.so my question is can your application be modified and it take input from user and then display the min and maximum time.

Thanks and Regards

In principle, it's possible to modify the code so that the tool will employ user-generated input instead of the auto-generated keystrokes. However, such a modification is hardly practical, because, in software, there's no significant difference between those cases, yet there's no way to precisely control the timing of user-generated input (which is required to make the results reproducible).

If you want to measure "physical" keyboard input lag, you need to use a hardware-based solution.
