A study developed a new computer program that can estimate human emotion through a person’s style of typing.

The study was conducted by researchers from the Islamic University of Technology in Bangladesh. Their goal was to use a technological process that can detect emotion from a person’s computer keystrokes. To do this, the researchers developed a program using various computer formulas.

This program analyzes the characteristics of a person’s keystroke. These characteristics include speed, rhythm of typing pattern, and pauses between pressing and releasing a key. The researchers then examined the program’s data alongside the questionnaires filled out by the participants to identify any of the seven basic emotions, some of which are anger, joy, and sadness.

The program was able to accurately detect two emotions. Based on results, the program correctly identified “joy” 87 percent of the time and “anger” 81 percent of the time. Sadness was the least recognized, with only 60 percent accuracy. This was because participants were less willing to indicate their true emotions to the study’s process when in a negative mood, the researchers explained.

Also, the whole process itself was limited to reading the participants’ typing style and textual statements. It did not consider spontaneous emotion indicators like facial expressions.

Regardless of its limitations, the study’s program may open new doors to building technological machines that are emotionally-oriented and, therefore, more user-friendly. The researchers stated that their program can be a useful tool in developing better online education systems. For instance, content and teaching methods can be made adjustable to the students’ emotional state.
