In late June 2017, Apple Inc. announced that it has acquired SensoMotoric Instruments in Germany, a leading provider of Computer Vision technology for a wide range of applications including autistic child treatment and cognition. Learning and training, language learning, marketing research, sports health, psychology research, virtual reality / augmented reality and many other fields.
According to several overseas media reports, Apple's acquisition of SensoMotoric Instruments is mainly aimed at strengthening its technical layout on AR glasses. However, looking at technology companies' acquisitions of technology providers, Apple may not use the acquisition for a specific product, whether it is from SensoMotoric Instruments' own capabilities or eye tracking applications. Scope, this is an area of ​​imaginative space.
What is eye tracking?
Eye Tracking is the process of measuring the movement of the eyeball relative to the head, while the eye tracker is the instrument used to measure eye position and eye movement. The world around us is 360 degrees, but human eyes can only see 120 degrees of things, and people's eyes will only focus on small areas of no more than 6 degrees in the field of view, and the surroundings are blurred. In the actual time of 19, it was observed that when humans read the text, the eyes were not swept away in the text of the book, but a very short pause and a very short visual jump occurred.
And this observation has also led to new thinking: what text does our eyeball stay on? How long has it stayed? When did it retreat to the text we have seen before? From this allusion, it actually reflects Eye tracking is not a completely new technology. Today, research on eye tracking technology has been going on for decades, and most technology companies have more or less layout in this field.
What is the relationship between eye tracking and educational technology?
Tobii is a Swedish technology company dedicated to the development of eye tracking technology. The company was founded in 2001. Tobii received a $14 million investment from Investor Growth Capital in 2007. In 2009, it received another $16 million in investment from Amadeus Capital Partners and Northzone Ventures. In 2012, it received a $21 million investment from Intel Corporation. The company was listed on the Stockholm Stock Exchange in Sweden in 2015. Tobii's products sell products and services to the world through agents and partners, and currently have offices in the United States, Germany, China, Japan, Ukraine, Norway and other countries.
Tobii's eye tracking technology has also been tried in the field of education. Its eye tracking technology can understand the data of students' learning behaviors and teacher teaching methods in different forms of classroom teaching. Data from eye tracking can help teachers and researchers better understand the student's learning load and can be used to assess whether teachers' teaching methods are effective.
In a Tobii university trial in the United States, the purpose of the study was to examine the student's attention in the classroom to identify factors that would maintain the student's attention during the teaching process and to achieve the goal of keeping the student in the classroom. Engagement and enthusiasm for teaching skills. The researchers conducted research on three aspects: What are the concerns of the students during the classroom instruction? What distracts the students' attention? What are the factors that can keep the students in the classroom?
Tobii's eye tracker recorded 70 minutes of data, including audio, video, and the subject's gaze position (indicated by dots). The screenshot below is a screenshot of the data from the eye tracker output, showing a chart of a participant's observation in the lecture when the instructor interprets the results of the quiz.
Tobii's research found that students pay little attention to lecturers, regardless of other factors, instead they focus on slides or observe their notes. But there are also obvious exceptions. For example, when the lecturer becomes very active, when writing on the blackboard, using humorous words or explaining content other than slides, students will have a tendency to observe the lecturer. Students will also pay attention to the lecturer when the lecturer explains the answers to the weekly test. Finally, the student's Q&A session will have the opposite result.
It's not surprising that the most distracting factors are students. Typing or surfing the Internet (usually Facebook) is a major factor in distracting students, although these behaviors are not recommended in the classroom. Other students in the class are also one of the factors that distract attention. There are also some factors that come from where students sit in the classroom.
