For university classrooms, are telepresence robots the next best thing to being there?

The findings are notably essential given the nationwide shift to on-line instruction brought on by the COVID-19 pandemic, forcing many college students who in any other case can be in school rooms and labs to pursue their schooling from a distance.

The Nationwide Science Basis research led by Naomi Fitter of the OSU Faculty of Engineering examined the experiences of college college students attending courses in three codecs: in particular person; by way of a telepresence robotic; and through distance studying instruments similar to livestreaming, recorded lectures and calling into class with questions.

Findings have been revealed in Robotics and Automation Letters.

The preferences of the 18 engineering college students who have been studied have been break up between distance studying instruments, or DLTs, and attending in particular person. Instructors of the 4 programs within the research uniformly most popular instructing college students in particular person.

However the instructors felt telepresence robots have been preferable to distance studying instruments for distant studying, and the scholars famous the robots’ potential to maintain them extra engaged, expressive and self-aware.

Even earlier than the pandemic, Fitter notes, 14% of college college students in the USA have been pursuing levels completely on-line, and one other 15% have been utilizing distance studying applied sciences at the very least a few of the time.

“College students have interaction in distance studying for a lot of causes,” she mentioned. “There are basic challenges in distance studying, similar to the necessity to discover a method to prepare college students within the time administration and lively listening abilities sometimes developed throughout increased schooling. Distance learners are additionally inclined to lacking out on benefiting from their friends — efficient social interplay whereas studying results in higher essential considering and longer-term info retention.”

The person interface for the robots within the research included forward- and downward-facing digicam views, zooming choices, mouse- and keyboard-based robotic driving, and menus for adjusting audiovisual parts.

“Previous analysis has explored the usage of telepresence robots in all kinds of contexts together with hospitals, workplaces, museums and professional conferences,” Fitter mentioned.

Individuals within the research, which additionally included researchers Nisha Raghunath and Christopher Sanchez of the OSU Faculty of Liberal Arts, attended class through every assigned methodology for a two-week interval. The programs have been 4 medium-sized, upper-level engineering courses — machine studying, software program architectures, evaluation of algorithms, and pc programs group — consisting primarily of conventional lectures in a classroom, with pupil participation inspired.

The OSU researchers and collaborators on the College of Southern California and the College of California, Santa Cruz, entered the research with three hypotheses:

• Attending class in particular person will result in higher self-reported studying outcomes for college kids.
• Utilizing the telepresence robotic will result in higher emotions of presence and self-expression than the space studying applied sciences — the emotions of presence when utilizing a robotic will likely be nearer to the emotions of presence when attending class in particular person than by way of distance studying strategies.
• When college students are unable to attend class in particular person, they and their instructors will want telepresence robots as a distant studying resolution over distance studying strategies.

“Individuals typically used the robots to view the lecture, ask questions throughout the lecture, and transfer round throughout breaks to speak to mates or instructors,” Fitter mentioned. “When requested to decide on a single favourite methodology for attending class, 9 contributors selected in-person attendance, eight selected the DLT sources, and one selected the telepresence robotic.”

In-person studying ranked increased than the opposite attendance strategies in each side of a every day survey accomplished by contributors aside from ease of studying, wherein it tied with distance studying applied sciences. In-person studying was described as extra social and individually expressive in comparison with different studying strategies, and emotions of presence and interplay talents have been additionally higher in particular person.

“Not all college students had realized the worth of in-person studying earlier than the research,” Fitter mentioned. “Instructors uniformly most popular in-person attendance by college students. However there have been drawbacks to in-person studying too, similar to ‘an individual sits beside me and is at all times speaking.'”

Of their post-study interviews, pupil contributors typically provided constructive feedback in regards to the robots however famous imperfections like “there have been occasions once I was not in a position to learn from the display correctly” and “I wasn’t positive about my talking quantity.”

“If a telepresence robotic does not have enough digicam high quality, investing in different new options for it might be futile,” Fitter mentioned.

Instructors for essentially the most half appreciated with the ability to see college students’ faces and nonverbal expressions whereas expressing a desire for distant college students attending class utilizing a telepresence robotic.

“Regardless of reporting sure challenges, contributors appeared to have general constructive experiences utilizing the telepresence robots,” Fitter mentioned. “Understanding use applied sciences to maintain individuals linked will improve in significance on this world of more and more spread-out households, groups and courses.”
