AbstractIn the healthcare domain, head-mounted displays (HMDs) with augmented reality (AR) modalities have been reconsidered for application as a result of commercially available products and the needs for using computers in mobile context. Within a user-centered design approach, interviews were conducted with physicians, nursing staff and members of emergency medical services. Additionally practitioners were involved in evaluating two different head-mounted displays. Based on these measures, use cases and usability considerations according to interaction design and information visualization were derived and are described in this contribution.

Optical head-mounted displays (OHMDs) could support members of emergency medical services in responding to and managing mass casualty incidents. In this contribution, the authors describe the human-centered design of two applications for supporting the triage process as well as the identification of hazardous materials. They were evaluated with members of emergency medical services and civil protection units. In this regard, challenges and approaches to human-computer interaction with OHMDs in crisis response and management are discussed. The conclusion is drawn that often mentioned advantages of OHMDs like hands-free interaction alone will not lead to usable solutions for safety-critical domains. Interaction design needs to be carefully considered right down to the last detail.

Energy Domain

Long-term energy saving and reduction of environmental consequences of energy consuming are among the most challenging objectives of our time. People are prone to routine and habit. To change these habits is almost a Sisif’s work. In spite of continuous efforts from environmental specialists, we are witnessing an increase in electricity (and gas) consumption, at least at the level of households. Studies carried on have shown that consumers have in many cases an irrational behaviour. To correct that, researchers are studying consumers’ decision making behaviour and try several intervention measures. In our paper we are presenting the design and development of a web based adaptive system aimed to educate citizens for an electrical energy saving behaviour. The system is composed of three subsystems: adaptation system, user’s profile and knowledge base. We have used a user-centered design approach. For adults, users’ profiles are build taking into account age group, educational level, gender, income, professional aspects, consuming behaviour. A set of questionnaires have been designed in order to collect users’ data. For children, the standard profiles are more complicated and, in function of the age group, can be obtained off line through interviews or/and through online activities (games, quizzes etc.). The knowledge base is build for the electrical energy domain. The adaptation sub-system will present information to the user based on s/he profile. The system is populated with data for users of 6 to 10 years of age. For this users group a social and affective interaction design approach was used.

Crossing, or goal crossing, has proven useful in various selection scenarios, including pen, mouse, touch, and virtual reality (VR). However, crossing has not been exploited for freehand selection using augmented reality head-mounted displays (AR HMDs). Using the HoloLens, we explore freehand crossing for selection and compare it to the state-of-the-art “gaze and commit” (head gaze) method. We report on three studies investigating freehand crossing in multiple use cases. The first study shows that crossing outperforms head gaze in selection scenarios of varying target arrangements. The second explores crossing, head gaze, and hand pointing in radial menu and dynamic interface scenarios. The third explores crossing as a function carrier for a variety of basic interaction functions in a drawing application. This work builds on existing knowledge on the goal-crossing paradigm by demonstrating its potential as a useful interaction method in 3D AR HMD interfaces.

Business Placement Center membantu mengelola website alumni dalam memenuhi kebutuhan alumni salah satunya memberikan informasi mengenai lowongan pekerjaan. Website Alumni Amikom sudah memberikan informasi mengenai lowongan pekerjaan. Namun website alumni masih perlu ditambahkan fitur-fitur menu penunjang dalam mempermudah pencarian informasi pekerjaan yang sesuai keinginan pengguna. Penggunaan metode User Centered Design untuk mempermudah pengguna dalam menggunakan fasilitas yang ada pada website ketika mencari informasi lowongan pekerjaan dan pengguna berperan penting dalam setiap proses UCD. Dengan pendekatan User Centered Design diharapkan dapat menghasilkan tampilan dan fungsionalitas yang maksimal pada rancangan sistem yang dibangun sehingga sesuai dengan kebutuhan pengguna. Metode penelitian yang dilakukan yaitu observasi, wawancara dan kuesioner untuk mengetahui kebutuhan pengguna. Analisis dan perancangan menggunakan pendekatan User Centered Design dan implementasi perancangan sistem. Hasil penelitiannya adalah pengguna merasa nyaman dengan tampilan antarmuka website yang sudah dibangun, informasi yang disajikan mudah dipahami dan fitur-fitur menu sudah berhasil berjalansesuai fungsi.Business Placement Center help manage the website for the needs of alumnus one of them is to provide information on a vacancy. The alumnus website’s provides information about job vacancy. The website still need the support to facilitate the searching all the features the work in accordance with what the use. The method of user centered design to make it easy for users in the use of the existing facilities at the website while searching for information a vacancy and users play an important role in any proses UCD. User Centered Design approach is expected to produce the interface and functionality maximal built in the system so that in accordance with the need of users. Research methodology was by observation, interviews and quesionnaires to find out the need of users. Analysis and design using UCD approach and implementation of the system. The results of research is users feel comfortable with a display interface of website which have been built, the information is easily understood and menu features has been successfully run a function.

This chapter introduces the field of computational interaction, and explains its long tradition of research on human interaction with technology that applies to human factors engineering, cognitive modelling, artificial intelligence and machine learning, design optimization, formal methods, and control theory. It discusses how the book as a whole is part of an argument that, embedded in an iterative design process, computational interaction design has the potential to complement human strengths and provide a means to generate inspiring and elegant designs without refuting the part played by the complicated, and uncertain behaviour of humans. The chapters in this book manifest intellectual progress in the study of computational principles of interaction, demonstrated in diverse and challenging applications areas such as input methods, interaction techniques, graphical user interfaces, information retrieval, information visualization, and graphic design.
