Given the accelerated changes and deeply interconnected activities of the times we are living in, creativity is a key factor of disruptive future developments. Creative and entertainment industries nowadays represent more than 3% of the GDP in Europe and they range from creative content providers (TV & radio, fashion, music) through creative experience providers (movies and music experience) to creative services providers (advertising, design, architecture).

Creative services, contents and experiences present knowledge requirements that are defined increasingly beyond a single discipline and appear to lie in a sound engagement among the creative practitioner (artist/designer/composer/entertainer), the engineer and the scientist. Digital arts, creative industries, and (tele)communication + (social) signal processing speak the language of convergence rather than autonomy. Their interaction calls for special attention now more than ever.

The journal is not limited to only specific aspects of creative technologies but also open to considering the high-level and innovative contributions from a wide range of subfields, especially articles of interdisciplinary nature.

Some of the journal topics are:

Creative Industries - the paper can describe a whole industrial project or framework integrating creative technologies for domains such as:

Creative content providers: TV & radio (broadcast, linked media), fashion (RFID and sensors, energy recycling), music & movies, books (digitization, sonification), museums (creative/artistic installations for tourism or cultural heritage) and media archives, etc.
Creative services providers: Advertising (user-centered web and ads optimization), design (communication devices for creative environments), architecture (places that adapt to people, creativity from domotics), new media and transmedia, etc.
Creative experience providers: Movies and music experience, game-based installations and playable media (participative creation, DJs and VJs creative tools), interactive social and urban spaces, etc.

Scientific topics - the paper can focus on scientific tools for creative industries on topics such as:

Creative content management: Multimedia data mining and innovative browsing, data 2D/3D visualization, digitization and storage, cultural heritage, etc.
Creative interactions: Social signal processing, verbal and nonverbal, explicit or implicit interactions, interacting robots, sensors and MoCap, human-computer interaction, user interface design, serious game etc.
Creative experiences: Affective content analysis and synthesis, immersive technologies, special effects, augmented reality, expressivity and emotion detection and processing, user experiences, etc.

Additional materials such as videos of installations and setups, public/users reactions and comments, or demo links are welcome.

Call for Papers: ICDM 2021 (Manuscript submission deadline: 2021-10-15; Notification of acceptance: 2021-12-10; Submission of final revised paper: 2022-01-21; Publication of special issue (tentative): 2022-02-04)

With the development of artificial intelligence and increased computer power, programmed prediction approaches have demonstrated that they are increasingly effective in predicting stock values. In this study, the Artificial Neural Network, LSTM, and LR techniques were used to predict the closing price for the following day for five companies belonging to different business sectors. In today's economy, the stock market or equity market has a profound
influence. The prediction of stock prices is quite complex, chaotic, and it is a big challenge to have a dynamic environment. Behavioural finance means that investors' decision-making processes are affected by emotions and attitudes in response to particular news. In order to help investors' judgements, we have supplied a technology for the analysis of the stock exchange. The method combines historical price prediction. For predicting, LSTM (Long Short-Term Memory), ANN and LR are employed. It includes the latest information on trade and analytical indicators. Financial data: Open, high, low and close stock prices are used to build new variables needed for model input. The models are validated with standard strategic indicators: RMSE and MAPE. The low values of these two variables indicate that the models are cost-effective.

This rising Internet bandwidth speed has made video data transmission a more popular and modern form of information exchange. For classification of video date files there is a requirement of human efforts. Also for reducing the rate of clutter in video data on Internet, a suitable automatic video classification method is required.

OBJECTIVES: In this work, we tried to find a successful model for video classification.

METHODS: To make a successful model we use different schemes of visual and audio data analysis. On the other hand we choose some music, traffic and sports videos for different analysis. The model is based on Hidden Markov model (HMM) and Artificial neural network (ANN) classifiers. In order to gather the final results, we developed an “enhanced ANN-HMM based” model.

RESULTS: Our approach attained an average of 90% success rate among all three classification classes.

CONCLUSION: In aim of this work is to categorize and caption the videos automatically. Here we proposed an enhanced HMM-ANN based classification of video recordings with the aid of audio visual feature extraction.

One of the key figures in Mahayana Buddhism is the celestial Buddha Amitabha, also known as the Buddha of Infinite Light. Several Buddhist texts describe the “Sukhāvatī” the land that that Amitabha inhabits. The texts not only describe the physical characteristics of this environment but also the soundscape. This paper discusses the process of transcoding an image of Amitabha into sound to create an interactive sonic environment. This process explores how choosing sounds based upon the literary description, can be a way of creating a link between an image and the literary counterpart.

OBJECTIVES: In this project we created a VR AudioVirtualizer able to generate graphics in response to any sound input in a visual style similar to a body of drawings by the first author.

METHODS: In order to be able to make the system able to respond to any given musical input we developed a Unity plugin that employs real-time machine listening on low level and medium-level audio features. The VR deployment utilized SteamVR to allow the use of HTC Vive Pro and Oculus Rift headsets.

RESULTS: We presented our system to a small audience at PROTO in Gateshead in September 2019 and observed people’s preferred ways of interacting with the system. Although our system can respond to any sound input, for ease of interaction we chose four previously created audio compositions by the authors of this paper and microphone input as a restricted set of sound input options for the user to explore.

CONCLUSION: We found that people’s previous experience with VR or gaming influenced how much interaction they used in the system. Whilst it was possible to navigate within the scenes and jump to different scenes by selecting a 3D sculpture in the scene, people with no previous VR or gaming experience often preferred to just let the visuals surprise them. They used mainly head movement to change their point of view, whereas people with previous VR or gaming experience quickly learned inherent capabilities of the system. The AudioVirtualizer system is most suited to respond to electronic soundscapes and microphone input.

In this discussion, the term ‘gesture’ indicates a movement of the body consciously performed and able to express or communicate something. The expression ‘cognitively plausible’ refers to an interactive sound response that is immediate, continuously varying and enactively coherent with the generating (sonified) gesture.

OBJECTIVES: The objectives of this paper are two. The first is an artistic exploration of gesture sonifications in various contexts. The second is rather methodological, i.e., to provide a possible general paradigm for Artistic Research (AR).

METHODS: More in detail, the AR phenomenological approach is modeled according to an Interaction Design (IxD) research paradigm.

RESULTS: A number of case studies of gesture sonification are presented and discussed according to the above methodological framework.

CONCLUSION: We claim that the introduction of such methodological framework was successful in terms of providing robust guidelines for our research and for a clear and structured presentation of its results.

The conventional method of calling name of each student is time consuming and there is always a chance of proxy attendance. The following system is based on face recognition to maintain the attendance record of students. The daily attendance of students is recorded subject wise which is stored already by the administrator. As the time for corresponding subject arrives the system automatically starts taking snaps and then apply face detection and recognition technique to the given image and the recognize students are marked as present and their attendance update with corresponding time and subject id. We have used deep learning techniques to develop this system, histogram of oriented gradient method is used to detect faces in images and deep learning method is used to compute and compare feature facial of students to recognize them. Our system is capable to identify multiple faces in real time.

Considering that Art reflects social, cultural and sometimes political realities, we identify types of messages that an artwork using advanced technological might transmit to us, spectators or artists. This paper focusses on the Cyborg Theatre, whereby the technology is its inherent element without which the performance could not happen. Such a technological performance cannot occur without a body. We refer here to a cyborg body as a human organism extended with mechanical parts, which integrate non organic components in order to gain meaning within the artwork. By focusing on such a theatrical performance, we observe a relationship developing between the performer and the spectator. This is an unusual interaction, which deserves our attention. We claim that both the performer and the spectator take part in a social event that does not only represent societal realities, but also indicates future ones.

This study reports on research into the impact of digital technological interventions for including kids with attention and developmental dificulties into school class contexts. The paper describes, how the authors have approached the challenge of researching inclusion of kids with attention and developmental deficits for communication, collaboration and knowledge sharing. Some of the questions addressed in the study are: How – and in what sense - may technology and technological interventions be utilised to enhance this approach with our focus learners? In which situations does it occur in the case study? The data analysis assesses the potential of interventions with digital technology for acting as stimulating enzymes for life and learning. On the basis of a thorough discussion of the analysis and findings, the authors assess the degree to which interventions with digital technologies may promote inclusion through stimulating the participation in life and learning of kids with attention and developmental deficits.

The amplifier was designed and simulated using large signal Si-LDMOS transistor model to achieve 53% PAE, 41dBm Pout, 14 dB gain at P1dB saturation point. The proposed balanced RF power amplifier was fabricated and measurement results for phase variation of the signal between the carriers have been the main focus. At 1dB compression point power added efficiency increased to 81.5% with 19.5 gain at the Pout. The AM-AM and AM-PM measured data of the balanced RF power amplifier was extracted from the MATLAB fitting tool to produce polynomials. The polynomials were used in the proposed pre-distortion technique to compensate for the nonlinearities of the balanced power amplifier. A simple linear model was designed for behavioural modelling of the memory-less baseband digital pre-distorter. A Simulink IEEE 802.11a OFDM Transceiver system was used to demonstrate validity of the proposed pre-distorter. To the best of authors’ knowledge, this study presented excellent results of predistortion system that compensated the nonlinearity behaviour of the balanced RF power amplifier using the Simulink version R2011a.

Recent studies have shown a significant gap between design frameworks and gamified products, reflected in a lack of consistency, integrity, measurement and a comprehensive process that covers the different phases to achieve a quality
gamified product. For this purpose, a specific quality model software for evaluation is required. Our contribution consists of making an analytical and qualitative study of the existing Gamification frameworks and platforms, with the aim of proposing a model for quality evaluation of the gamified applications. This proposal is based on the patterns and attributes determined during the conducted bibliographic study and comparative studies, with an attempt
to integrate the ISO 25010 quality model.

Highly complex models are a requirement for the successful delivery of many scenes and environments. While workflows such as rendering, compositing and animation have been streamlined to accommodate increasing demands, modelling complex models is still a laborious task. This paper introduces the computational benefits of an Interactive Genetic Algorithm (IGA) to computer graphics modelling while compensating the effects of user fatigue, a common issue with Interactive Evolutionary Computation. An intelligent agent is used in conjunction with an IGA that offers the potential to reduce the effects of user fatigue by learning from the choices made by the human designer and directing the search accordingly. This workflow accelerates the layout and distribution of basic elements to form complex models. It captures the designer’s intent through interaction, and encourages playful discovery.

The device differs from many traditional haptic feedback implementations in that it combines vibrotactile feedback with gesture based input, thus becoming a two-way conduit between the user and the virtual environment. The device is intended to challenge what is considered an “interface” and sets out to purposefully blur the boundary between man and machine. This allows for a more immersive experience, and a user evaluation shows that the intuitive interface allows the user to become the aircraft that is controlled by the movements of the user's hand.
