The Interface between Interactive Art and Human-Computer Interaction: Exploring Dialogue Genres and Evaluative Practices

The mutual efforts of joining art and science have been an important source of innovation in many fields throughout history. In this article, we investigate the relatively common origins, differences, and similarities between the Interactive Art and Human-Computer Interaction (HCI) areas of knowledge. We also investigate what kind of human-computer interactions are sought by artists or emerge in Interactive Art examples, as well as what kind of frameworks, evaluation criteria or methodologies are reported in the literature to support the design and evaluation of Interactive Art. As a result of our analysis of Interactive Art examples found in the literature and beyond, we derived four genres of dialogue that emerge naturally or are stressed by authors: visual, embodied, tangible and social. These genres, albeit not comprehensive, can inspire the design of novel forms of interaction in computational systems with or without artistic intent. Moreover, frameworks, evaluation criteria, and methodologies may allow a cross-pollination between Interactive Art and HCI. While interactive artists may provide novel ways to look at the design and evaluation of interactive systems, these artists may also benefit from appropriating traditional HCI methods, tools, and technologies for new purposes. Lastly, we draw on our findings and learned lessons to outline a research agenda with the main objectives of 1) encouraging Interactive Art research, 2) studying Interactive Art examples, 3) practicing Interactive Art design and evaluation, and 4) designing Interactive Art for all.

Co-refining Interactive Systems with Older Adults from Function, Form and Interaction

Designing interactive systems that are pragmatic, attractive and easy to use for older adults is challenging. Participatory design, as an approach to enhance the mutual understanding between designers and end users, has been proved to be useful to improve the quality of design for older people. However, PD research has long been criticized for extensively dealing with the early-phase design while putting less emphasis on the later stages. In this paper, we argue for the importance of collaborative refinement when designing interactive systems for older adults. Through a case study, we describe our experience of co-refining the preliminary design of an interactive system with older participants from three perspectives: function, form and interaction. We also explored to adopt some potential PD methods and conclude by discussing the effectiveness of the chosen approach and methods.

Design Of E-Document System With Digital Signature Using User Centered Design Method

UCD (User Centered Design) is a design philosophy that places the user at the center of a system development process. The UCD approach has been supported by various techniques, methods, tools, procedures and processes that help design interactive systems that are more user-centered. This study aims to apply UCD in the design of e-document systems with digital signatures to determine user requirements for system functionality and interfaces. To find out the extent of the application of the UCD, a measurement of the level of acceptance and support of prospective users is used by making a data collection instrument in the form of a questionnaire according to the usability testing framework by using a Likert scale to calculate the variables. The results of testing of potential users showed that 85% stated that the functionality and interface design of the e-document system with digital signatures and can be developed in the next stage.

Discovering the Sweet Spot of Human-Computer Configurations

Interactive intelligent systems, i.e., interactive systems that employ AI technologies, are currently present in many parts of our social, public and political life. An issue reoccurring often in the development of these systems is the question regarding the level of appropriate human and computer contributions. Engineers and designers lack a way of systematically defining and delimiting possible options for designing such systems in terms of levels of automation. In this paper, we propose, apply and reflect on a method for human-computer configuration design. It supports the systematic investigation of the design space for developing an interactive intelligent system. We illustrate our method with a use case in the context of collaborative ideation. Here, we developed a tool for information extraction from idea content. A challenge was to find the right level of algorithmic support, whereby the quality of the information extraction should be as high as possible, but, at the same time, the human effort should be low. Such contradicting goals are often an issue in system development; thus, our method proposed helped us to conceptualize and explore the design space. Based on a critical reflection on our method application, we want to offer a complementary perspective to the value-centered design of interactive intelligent systems. Our overarching goal is to contribute to the design of so-called hybrid systems where humans and computers are partners.

The Research and Implementation of Interactive Media Art Design System

Interactive media art is an important part of the new cultural industry, is a typical combination of art and technology, which combines visual, auditory, space design, light, electricity and other forms of effect to fresh vibrant feeling. Interactive media art is widely used in exhibition industry, interactive advertising, stage art and performance, interactive games and other fields. China’s interactive media art has just entered a stage of rapid development, there is no ready-made universal interactive media design system, which is the bottleneck of the development and application of interactive media in china. This paper first carries out research on interactive media system involves hardware and software development technology, then explain the interactive media art and design of each subsystem and their design method and implementation process. In this system, we design and implement a set of visual programming model based on node, and develop a friendly interactive authoring environment, visual interactive subsystem and a powerful plug-in system.

Tangibly understanding intangible complexities: Designing for distributed autonomous organizations

Abstract New digital technologies such as Blockchain and smart contracting are rapidly changing the face of value exchange, and present new opportunities and challenges for designers. Designers and data specialists are at the forefront of exploring new ways of exchanging value, using Blockchain, cryptocurrencies, smart contracting and the direct exchanges between things made possible by the Internet of Things (Tallyn et al. 2018; Pschetz et al. 2019). For researchers and designers in areas of Human Computer Interaction (HCI) and Interaction Design to better understand and explore the implications of these emerging and future technologies as Distributed Autonomous Organisations (DAOs) we delivered a workshop at the ACM conference Designing Interactive Systems (DIS) in Edinburgh in 2017 (Nissen et al. 2017). The workshop aimed to use the lens of DAOs to introduce the principle that products and services may soon be owned and managed collectively and not by one person or authority, thus challenging traditional concepts of ownership and power. This workshop builds on established HCI research exploring the role of technology in financial interactions and designing for the rapidly changing world of technology and value exchange (Kaye et al. 2014; Malmborg et al. 2015; Millen et al. 2015; Vines et al. 2014). Beyond this, the HCI community has started to explore these technologies beyond issues of finance, money and collaborative practice, focusing on the implications of these emerging but rapidly ascending distributed systems in more applied contexts (Elsden et al. 2018a). By bringing together designers and researchers with different experiences and knowledge of distributed systems, the aim of this workshop was two-fold. First, to further understand, develop and critique these new forms of distributed power and ownership and second, to practically explore how to design interactive products and services that enable, challenge or disrupt existing and emerging models.

Designing for the Mindbody in Technology-Mediated Music-Making

The mind and body have an important joint role to play in how we experience, understand and create music. Our bodily experiences in the world shape how we comprehend music. In turn, our mind's music cognition and intentionality, which are based on our bodily experiences, are mediated through the body when we make music. This mind-body interaction has provided important contributions to the intelligibility, relatability and embodiment of our musical experiences, yet this dynamic is not always intact in today's technology-mediated music-making. Employing practice-based and practice-led methodologies, my research explores the potential of considering the mindbody in the design of interactive computer systems for music-making. This paper outlines the motivation, context, research methodology, and completed and future projects of my research towards a Doctor of Philosophy in Music with a specialization in Computational Media Design.

GenYacht: An interactive generative design system for computer-aided yacht hull design

In the present work, a new digital design system, GenYacht, is proposed for the creation of optimal and user-centred yacht hull forms. GenYacht is a hybrid system involving generative and interactive design approaches, which enables users to create a variety of design alternatives. Among them, a user can select a hull design with desirable characteristics based on its appearance and hydrostatics/hydrodynamic performance. GenYacht first explores a given design space using a generative design technique (GDT), which creates uniformly distributed designs satisfying the given design constraints. These designs are then presented to a user and single or multiple designs are selected based on the user’s requirements. Afterwards, based on the selections, the design space is refined using a novel space-shrinking technique (SST). In each interaction, SST shrinks the design space, which is then fed into GDT to create new designs in the shrank space for the next interaction. This shrinkage of design space guides the exploration process and focuses the computational efforts on user-preferred regions. The interactive and generative design steps are repeated until the user reaches a satisfactory design(s). The efficiency of GenYacht is demonstrated via experimental and user studies and its performance is compared with interactive genetic algorithms.

User-Centred Design in Content Management System Development: The Case of EMasters

Including users in design and development of an interactive product is crucial to achieve high level of usability. Content management systems have two categories of users, content creators and content consumers, and designers of these systems have to considers the needs of both user groups. In design of interactive learning systems, special attention has to be given to the process of learning, which means that functional, accessible and usable interface has to serve the purpose of knowledge acquisition. Designing for mobile learning brings additional challenges due to the small screens of mobile devices. The paper describes the process of utilization of user-centred design in development of a simple content management system for learning called EMasters. The aim of the EMasters is to enable teachers to easily create and organize courses which will be delivered to students to facilitate web-based and mobile learning. According to the user-centred design approach, teachers and students are involved in iterative process of design, implementation and evaluation of EMasters. Evaluation study used complementary methods and provided quantitative and qualitative feedback. The usability score reached good level and the guidelines for redesign of the system interface are drown. According to the obtained results, proposed framework is confirmed to be applicable in user-centred design of content management systems in general. In addition, the directions for adjustment of the framework for specific cases are provided.

On the visual reality and monitoring of gantry cranes using FBG sensing

ABSTRACT The gantry crane is an important and representative rotary rail loading and unloading crane. In order to ensure the safe and reliable operation of the gantry crane, it is particularly important to monitor its condition. Many ports still use the traditional after-sales maintenance system. And, the equipment and means for fault detection and repair are also backward. This paper proposes a design of a human-computer interaction system for gantry crane equipment on-line monitoring. The virtual reality technology is used to display the monitoring data and analysis results of the gantry crane in the three-dimensional space in real time. We sample the stress and temperature signals of the gantry crane using Fibre Bragg Grating sensors installed in some structural key points. The sensors are connected to the fibre grating demodulator of the monitoring room through a transmission fibre. Signals collected by the sensors are processed and analysed to diagnose the condition of the gantry crane. The system presents the crane’s operating status to the user in a realistic ‘virtual environment’, so that the fault information can be quickly and accurately fed back.

Objective monitoring of attentional states based on collaborative force-position control tasks

Accurate haptic interaction tasks require intensive activation of attentional resources. Exploring the relation between haptic channel and attention is not only conducive to understanding the interaction mechanism between human perception and cognition but is also important for the design of brain-computer interaction system based on haptic modality. In this paper, we built a virtual reality environment incorporating the multiregion force feedback and immersive visual displays and developed a collaborative force-position control task to monitor the attentional states objectively based on this platform. The force and position control performances of users at four different difficulty levels were used to measure the attentional level and attentional spotlight. The users subjective assessment showed that the task can effectively activate attentional resources. The experimental results showed that the task can be used as an attentional oscilloscope to monitor the changes in the attentional level and target of attentional spotlight with a high temporal resolution, providing a behavioral ground truth for exploring attentional biomarkers.

Disturbance-Observer-Based Compliance Control of Electro-Hydraulic Actuators With Backdrivability

This letter proposes an intrinsically backdrivable electro-hydraulic torque actuator (EHTA) and associated control algorithms that could lead to the design of a high-performance interactive robot system. The EHTA consists of (electro-hydraulic) backdrivable servovalves and double vane rotary hydraulic actuators. It is represented as a flexible actuator model considering servovalve dynamics and fluid dynamics. In the flexible actuator structure, the interaction stability is not guaranteed because the EHTA is a noncollocated system. However, due to the use of backdrivable servovalves, the EHTA is rigidly represented in the finite frequency region that a robot operates in daily life; it has the property of finite frequency passivity. Based on this property, a disturbance observer was designed to compensate for friction effects and model uncertainties. Then, the compliance control was applied to the friction-free actuator. Consequently, we achieved the actuator with a torque sensitivity of 0.1 Nm and a maximum torque output of approximately 100 Nm. The proposed actuators and controllers were evaluated through experiments.
