During our research, we became aware of XRAI, the provider of the augmented reality app <\/span><b>XRAI Glass<\/b><span style=\"font-weight: 400;\">which explicitly promotes its use in teaching\/learning settings. Specifically, live subtitling via augmented reality glasses is to be used to display subtitles directly below the person speaking, thereby reducing barriers for people with hearing impairments. <\/span><\/p>\n<p><span style=\"font-weight: 400;\">The app is installed on a standard smartphone connected to AR glasses. When we contacted the app developer at the end of 2022, we were initially given access to the beta version of the app, which could only be used on Android. XRAI Glass is now also available for iOS. <\/span><\/p>\n<p><span style=\"font-weight: 400;\">The setup in a live context includes the following components:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">A smartphone with the &#8220;Nebula&#8221; and &#8220;XRAI Glass&#8221; apps installed on it<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">The glasses incl.

An overview in three thematic blocks: <\/span>[\/vc_column_text]<div class=\"pn-headline-container  \n                        size-h2  \n                        font-weight-  \n                        text-transform-  \n                        color-  \n                        alignment-left\n                        icon-false\n                        h1\">\n                \n                <h2 id=\"\" class=\"inner-headline pn-headline\">1) Dealing with technology, app and data protection<\/h2>\n            <\/div>[vc_column_text css=&#8221;&#8221;]<span style=\"font-weight: 400;\">Before we got down to the actual practice, we introduced the students to the hardware and software mentioned above, which we provided. Although not all participants had worked with AR before, the familiarization went largely smoothly: after an initial demonstration, the students were able to use the apps and glasses independently. Only the XRAI app itself turned out to be a little sluggish, sometimes requiring several attempts to start it or bring the AR view to the desired height in the field of vision. <\/span><\/p>\n<p><span style=\"font-weight: 400;\">A bigger hurdle than the technical component is the major issue of <\/span><b>data protection.<\/b> <span style=\"font-weight: 400;\">Theoretically, there are several providers for subtitles and translations available via the app, but we only used Vosk to avoid storing them in the cloud. <\/span><\/p>\n<p><span style=\"font-weight: 400;\">The subtitles generated in this way are only saved locally, but if personal data is disclosed in the recorded conversation, it will appear in the transcript. An example: A student uses the XRAI app in a seminar where a discussion is taking place. The participants mention the names of their fellow students. This information would then be saved locally in the transcript as part of the conversation. <\/span><\/p>\n<p><span style=\"font-weight: 400;\">Our solution: For courses in which the glasses are to be used, we offer to explain the benefits and functionality to all participants in advance, i.e. also to &#8220;passive users&#8221;. The person using the XRAI undertakes in writing to delete the stored data promptly. This also represents a compromise in the face of individual concerns that the transcriptions would offer an advantage in examination situations &#8211; an aspect that once again made it clear to us that the principle of compensating for disadvantages is not present for everyone. <\/span>[\/vc_column_text]<div class=\"pn-headline-container  \n                        size-h2  \n                        font-weight-  \n                        text-transform-  \n                        color-  \n                        alignment-left\n                        icon-false\n                        h1\">\n                \n                <h2 id=\"\" class=\"inner-headline pn-headline\">2) Evaluation of subtitling<br \/>\n<\/h2>\n            <\/div>[\/vc_column][\/vc_row][vc_row][vc_column width=&#8221;1\/2&#8243;][vc_column_text css=&#8221;&#8221;]<span style=\"font-weight: 400;\">Once the bureaucratic and technical hurdles have been overcome, the actual use can begin. Anyone who has ever used automatic subtitling knows that it is not perfect and the choice of words is sometimes quite creative &#8211; for example, &#8220;digital teaching&#8221; sometimes becomes &#8220;guitar teaching&#8221;. Nevertheless, the assessment of the students with hearing impairments was optimistic, and the context made it clear what was meant, even in the case of errors. In cases where students have previously had an automatic transcription running on the screen in seminars, the AR aspect was also positively emphasized: This means you no longer have to constantly look back and forth between slides on the wall and a screen with subtitles. <\/span>[\/vc_column_text][\/vc_column][vc_column width=&#8221;1\/2&#8243;][vc_single_image image=&#8221;20922&#8243; img_size=&#8221;full&#8221; css=&#8221;&#8221;][\/vc_column][\/vc_row][vc_row][vc_column][vc_column_text css=&#8221;&#8221;]<span style=\"font-weight: 400;\">The international students were significantly more critical, which we attribute to various reasons: For example, they are less likely to use automatically generated subtitles and may therefore have a lower tolerance for errors. Secondly, reliability varies depending on the language. <\/span>[\/vc_column_text]<div class=\"pn-headline-container  \n                        size-h2  \n                        font-weight-  \n                        text-transform-  \n                        color-  \n                        alignment-left\n                        icon-false\n                        h1\">\n                \n                <h2 id=\"\" class=\"inner-headline pn-headline\">3) Overall impression<\/h2>\n            <\/div>[vc_column_text css=&#8221;&#8221;]<span style=\"font-weight: 400;\">In a survey, international students predominantly stated that they would not use the XRAI app. Their main concern was that the app looked too conspicuous. <\/span><\/p>\n<p><span style=\"font-weight: 400;\">Among students with hearing impairments, the conclusion is more tolerable. &#8220;At the beginning, [die Brille] may be a little awkward, but it becomes more manageable over time. However, you have to bear in mind that it is even more complicated without aids,&#8221; concludes Nick Massing, a digital media student who took part in one of the tests. Another student praises the subtitling, but criticizes the fact that the frame is not particularly flexible and therefore uncomfortable to wear over a longer period of time &#8211; all the more so for people who also wear normal glasses. <\/span>[\/vc_column_text][vc_single_image image=&#8221;20924&#8243; img_size=&#8221;full&#8221; css=&#8221;&#8221;]<div class=\"pn-headline-container  \n                        size-h2  \n                        font-weight-  \n                        text-transform-  \n                        color-  \n                        alignment-left\n                        icon-false\n                        h1\">\n                \n                <h2 id=\"\" class=\"inner-headline pn-headline\">Our conclusion and outlook<\/h2>\n            <\/div>[vc_column_text css=&#8221;&#8221;]<span style=\"font-weight: 400;\">Subtitling glasses like the XRAI are not a sure-fire success, as we are well aware after the tests we have conducted over the past few months. In terms of foreign languages, we now see them primarily as a means of giving students a practical understanding of the basic possibilities and functions of AR. <\/span><\/p>\n<p><span style=\"font-weight: 400;\">In the context of accessibility, we see glasses as <\/span><b>a solid addition <\/b> <span style=\"font-weight: 400;\">for short-term assignments such as lectures. However, it is also clear that it does not relieve teachers of their responsibility to break down barriers in other ways, e.g. by providing transcripts or notes. In addition, the <\/span><b>Group of students with hearing impairments is too heterogeneous<\/b><span style=\"font-weight: 400;\">to make a general judgment about their benefit.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The tests and feedback from people who are not affected have also shown us that there is still room for improvement in terms of awareness of accessibility. In particular, teachers and other event organizers must be aware that <\/span><b>Accessibility is not a &#8220;nice to add&#8221;<\/b><span style=\"font-weight: 400;\"> , but legal obligations exist and assistive technologies compensate for disadvantages. Where data protection and accessibility or audit rules and accessibility stand in the way of each other, willingness is required, <\/span> <span style=\"font-weight: 400;\">to find<\/span> <b>practical solutions<\/b>.<span style=\"font-weight: 400;\">We will continue to keep our eyes open for helpful technologies &#8211; but above all, we will remain in contact with the students concerned in order to recognize needs even where we are not aware of them at first, and to remove barriers wherever possible.<\/span>[\/vc_column_text]<div class=\"pn-headline-container  \n                        size-h2  \n                        font-weight-  \n                        text-transform-  \n                        color-  \n                        alignment-left\n                        icon-false\n                        h1\">\n                \n                <h2 id=\"\" class=\"inner-headline pn-headline\">Authors<\/h2>\n            <\/div>[\/vc_column][\/vc_row][vc_row][vc_column width=&#8221;1\/4&#8243;][vc_single_image image=&#8221;20909&#8243; css=&#8221;&#8221;][\/vc_column][vc_column width=&#8221;3\/4&#8243;][vc_column_text css=&#8221;&#8221;]<a href=\"https:\/\/www.linkedin.com\/in\/dabayer\/\"><span style=\"font-weight: 400;\">Daniel Bayer<\/span><\/a><\/p>\n<p><span style=\"font-weight: 400;\">Daniel Bayer is head of the Teaching Competence Center, which is the central point of contact at Mainz University of Applied Sciences for teaching design and development.
