OBJECTIVEAugmented reality (AR) is a novel technology that has the potential to increase the technical feasibility, accuracy, and safety of conventional manual and robotic computer-navigated pedicle insertion methods. Visual data are directly projected to the operator’s retina and overlaid onto the surgical field, thereby removing the requirement to shift attention to a remote display. The objective of this study was to assess the comparative accuracy of AR-assisted pedicle screw insertion in comparison to conventional pedicle screw insertion methods.METHODSFive cadaveric male torsos were instrumented bilaterally from T6 to L5 for a total of 120 inserted pedicle screws. Postprocedural CT scans were obtained, and screw insertion accuracy was graded by 2 independent neuroradiologists using both the Gertzbein scale (GS) and a combination of that scale and the Heary classification, referred to in this paper as the Heary-Gertzbein scale (HGS). Non-inferiority analysis was performed, comparing the accuracy to freehand, manual computer-navigated, and robotics-assisted computer-navigated insertion accuracy rates reported in the literature. User experience analysis was conducted via a user experience questionnaire filled out by operators after the procedures.RESULTSThe overall screw placement accuracy achieved with the AR system was 96.7% based on the HGS and 94.6% based on the GS. Insertion accuracy was non-inferior to accuracy reported for manual computer-navigated pedicle insertion based on both the GS and the HGS scores. When compared to accuracy reported for robotics-assisted computer-navigated insertion, accuracy achieved with the AR system was found to be non-inferior when assessed with the GS, but superior when assessed with the HGS. Last, accuracy results achieved with the AR system were found to be superior to results obtained with freehand insertion based on both the HGS and the GS scores. Accuracy results were not found to be inferior in any comparison. User experience analysis yielded “excellent” usability classification.CONCLUSIONSAR-assisted pedicle screw insertion is a technically feasible and accurate insertion method.

<p class="Abstrak">Rumah Sakit Semen Gresik merupakan fasilitas kesehatan yang ada di Kabupaten Gresik dengan akreditasi tingkat paripurna. Rumah Sakit Semen Gresik di kondisi pandemi saat ini mengalami penurunan jumlah pasien dan pendapatan, sehingga Rumah Sakit Semen Gresik berencana untuk menghadirkan layanan kesehatan yang dapat dilakukan di rumah menggunakan aplikasi untuk memudahkan pasien dalam mendapatkan layanan Kesehatan tanpa datang ke rumah sakit. Aplikasi yang dibangun harus memberikan kenyamanan saat digunakan oleh pengguna, maka dari itu perlu adanya rancangan <em>user experience. Design thinking </em>merupakan metode yang digunakan untuk merancang <em>user experience </em>pada aplikasi HomeCare dengan mendefinisikan permasalahan serta memberikan solusi desain yang dapat menyelesaikan permasalahan tersebut. Solusi desain selanjutnya diuji menggunakan <em>user experience questionnaire </em>(UEQ) untuk mengetahui apakah solusi desain yang dirancang sudah menyelesaikan permasalahan yang dialami oleh calon pengguna. Hasil dari pengujian menggunakan UEQ yaitu, untuk aplikasi HomeCare dengan pengguna pasien memiliki nilai <em>mean</em> tiap skala UEQ yang berada pada kategori positif dengan semua skala UEQ berada pada kategori baik kecuali skala <em>dependability </em>yang berada pada kategori sangat baik, sedangkan untuk aplikasi HomeCare Giver dengan pengguna tenaga kesehatan memiliki nilai <em>mean</em> tiap skala UEQ yang juga berada pada kategori positif dengan semua skala UEQ berada pada kategori baik kecuali skala <em>attractiveness </em>dan <em>novelty </em>yang berada pada kategori sangat baik<em>. </em>Sehingga aplikasi HomeCare dan HomeCare Giver memiliki rancangan <em>user experience </em>yang baik.</p><p class="Abstrak"><em><strong>Abstract</strong></em></p><p class="Judul2"><em>Semen Gresik Hospital is a health facility in Gresik Regency </em><em>with a paripurna level of accreditation</em><em>. Semen Gresik Hospital in a pandemic condition is currently experiencing a decrease in the number of patients, so that Semen Gresik Hospital plans to provide health services that can be done at home using an application to make it easier for patients to get health services without coming to the hospital. Applications that are built must provide comfort when used by users, therefore there is a need for a user experience design. Design thinking is a method used to design user experiences on the HomeCare application by defining problems and providing design solutions that can solve these problems. The design solution is then tested using a user experience questionnaire (UEQ) to find out whether the design solution designed has resolved the problems experienced by potential users. The results of the test using UEQ are, for the HomeCare application whose users are patient, the mean value of each UEQ scale is in the positive category with all UEQ scales in the good category except for the dependability scale which is in the very good category, while for the HomeCare Giver application whose the users are health workers, has a mean value of each UEQ scale which is also in the positive category with all UEQ scales in the good category except the attractiveness and novelty scales which are in the very good category. This can be concluded that HomeCare and HomeCare Giver applications have a good user experience design.</em></p><p class="Abstrak"><em><strong><br /></strong></em></p>

Modern Era

Technology inevitably evolves and develops rapidly in the modern era, industries and professions continue to strive in integrating, adapting and utilising these advancements to improve, optimise and improve the process of design to manufacture to the user experience. One such system that fits into this category is the advent of Virtual Reality and Augmented Reality. The numerous possibilities to which these visually and spatially immersive systems opportunities for immense innovation often lacks direction or an ultimate goal thus rendering this piece of software to often be little more than a visualisation tool.This paper recognises the unique position that VR allows and seeks to interrogate and deconstruct current, traditional design processes to better utilise VR in aiding and reinforcing the idea of partial testing of ideas and concepts throughout the design cycle. Different sciences such as psychology, processes and automation from computational design and considerations within software development will be employed and injected into the broader architectural context in which this research presides. In addition to the VR headset, eye tracking external hardware are integrated to develop a seamless tool and workflow that allows us, as designers to better interrogate clients behaviour within our designed digital representations which leads to validations, evaluations and criticisms of our actions within the architectural realm.

User Centered

Technical and professional communication (TPC) and user experience (UX) design are often seen as intertwined due to being user-centered. Yet, as widening industry positions combine TPC and UX, new streams enrich our understanding. This article looks at three such streams, namely, design thinking, content strategy, and artificial intelligence to uncover specific industry practices, skills, and ways to advocate for users. These streams foster a multistage user-centered methodology focused on a continuous designing process, strategic ways for developing content across different platforms and channels, and for developing in smart contexts where agentive products act for users. In this article, we synthesize these developments and draw out how these impact TPC.

Head Mounted Displays

Virtual Reality and Augmented Reality Head-Mounted Displays (HMDs) have been emerging in the last years. These technologies sound like the new hot topic for the next years. Head-Mounted Displays have been developed for many different purposes. Users have the opportunity to enjoy these technologies for entertainment, work tasks, and many other daily activities. Despite the recent release of many AR and VR HMDs, two major problems are hindering the AR HMDs from reaching the mainstream market: the extremely high costs and the user experience issues. In order to minimize these problems, we have developed an AR HMD prototype based on a smartphone and on other low-cost materials. The prototype is capable of running Eye Tracking algorithms, which can be used to improve user interaction and user experience. To assess our AR HMD prototype, we choose a state-of-the-art method for eye center location found in the literature and evaluate its real-time performance in different development boards.
