在课堂上增强现实交流的眼镜:向内看

【内向的学生有福了 增强现实交流的眼镜】Carlos III大学开发一个增强课堂反馈系统,教授可以通过它看到学生对课堂材料的理解。学生用手机标记他们是否跟上教授的解释,教授们需要佩戴增强现实的眼镜看到学生头上的符号,同时能看到聚合学生答案的饼状图。目前更符合人体工程学模型的AR眼镜正在开发中。

Scientists at Spain's Universidad Carlos III en Madrid developed a software system for augmented reality glasses that will allow professors to "see" how their students are understanding class material.
The proposed system, called Augmented Lecture Feedback System (ALFs), requires professors to wear augmented reality glasses in order to see symbols above students' heads and to facilitate communication between students and professors.
The symbols are activated by students via their cellphones, which allow them to indicate whether they are following the professor's explanations. In addition, professors will also be able to view a pie chart with the aggregate of students' answers.

"Many of [the students] are not keen on or feel inhibited by participating in the class. Sometimes they feel shy or they have fear to expose themselves in front of their classmates," wrote Telmo Zattaonandia, one of the researchers at the university, in an email. "An AR [augmented reality] device ... provides a communication channel unavailable previously between students and teachers which is private."
Ignacio Aedo, a tenured professor in the computer science department, said that the only problem is their weight. "Although the models of AR glasses available at the moment are suitable for research, they are still too heavy and cumbersome to be used on a daily basis," he said. More ergonomic models are in development for easier use, he added.
The glasses currently in use are a pair of Vuzix STAR 1200, but an integration of the ALFs into devices such as Google Glass seems to be a logical next step for the implementation of the technology.
Aedo continued:
We are really looking forward to to having a pair of Google Glass with us so we can develop a version of the ALF system for them. Of course it will be necessary to carry out some adjustments, as it seems that in this device only a small portion of the user's vision is augmented. It is very likely that we will have to sacrifice the symbols over the students' heads in favor of using pie charts and other ways of representing the summary of the responses from the students.
Ultimately, the creators hope to use the ALF system in other areas, such as office presentations and conference talks, Aedo added. "The main outcome of the system is that it provides a continuous flow of information from the audience."
