Abstract
While users tend to perceive instructional videos as an experience rather than a lesson with a set of instructions, instructional videos are more effective and appealing than textual user manuals and eliminate the ambiguity in text-based descriptions. However, most software vendors only offer document manuals that describe how to install and use their software, leading burden for non-professionals to comprehend the instructions. In this paper, we present a framework called M2V to generate instructional videos automatically based on the provided instructions and images in user manuals. M2V is a two-step framework. First, an action sequence is extracted from the given user manual via natural language processing and computer vision techniques. Second, M2V operates the software sequentially based on the extracted actions; meanwhile, the operation procedure is recorded into an instructional video. We evaluate the usability of automatically generated instructional videos via user studies and an online survey. The evaluation results show, with our toolkit, the generated instructional videos can better assist non-professional end users with the software operations. Moreover, more than 85% of survey participants prefer to use the instructional videos rather than the original user manuals.
