What kind of software is characterized by responding quickly to a learner's choices and commands?

Interactive video is the type of software that is characterized by responding quickly to a learner's choices and commands. This type of software allows learners to engage with the content in a dynamic way, making real-time decisions that can affect the outcome of their learning experience.

The interactivity embedded in such programs enables learners to receive immediate feedback, encourages active participation, and enhances retention by allowing users to explore scenarios or paths based on their selections. This adaptability is particularly beneficial in instructional settings, as it caters to diverse learning styles and paces, creating a more personalized and effective learning environment.

In contrast, static presentation slides provide information in a fixed format without interaction; programmed text follows a linear path where the learner does not influence the content and pacing directly. Projected material can be engaging but typically lacks the level of interactivity that distinguishes interactive video.
