“…The plausibility illusion, proposed by Slater [28], describes the illusion that the event in VR is really occurring. When it comes to interaction with virtual characters, achieving the plausibility illusion needs to fulfil three criteria: the characters should demonstrate responsiveness to the participant's behaviour: their behaviour should refer directly to the participant; and their behaviour should align with what the participant will expect in similar real-world scenarios [14].…”

Figure 1: Scenario with one actor jumping between several "agent avatars" and interacting with the user when necessary. (a) The user enters the scene and discovers three agent avatars. All three agent avatars are playing pre-recorded, loopable clips. Two of them portray customers while the third one acts as the barista. An actor, who is invisible to the user, is ready to take over any of the agent avatars and interact with the user. (b) The actor realizes that the participant intended to interact with agent avatar number 0, who is playing the role of a barista. Consequently, the actor plans to take control of that agent avatar and embody it to respond to and interact with the user. (c) The actor takes control of Avatar0 and is now interacting with the user. Meanwhile, all the other agent avatars continue to play their pre-recorded clips. (d) The actor releases control of Avatar0 and switches to another agent avatar to interact with the user. This creates the illusion that all three agent avatars were being controlled by real humans.

“…An emotionally guided virtual character can respond more convincingly to interactions with users and promotes user engagement. Therefore, developing a believable autonomous virtual character is still a challenging issue (Gillies, 2018). Moreover, simultaneously getting autonomy in some task and behaviors with emotion and personality traits require meeting multiples goals.…”

We have developed an autonomous virtual character guided by emotions. The agent is a virtual character who lives in a three-dimensional maze world. We found that emotion drivers can induce the behavior of a trained agent. Our approach is a case of goal parameterized reinforcement learning. Thus, we create conditioning between emotion drivers and a set of goals that determine the behavioral profile of a virtual character. We train agents who can randomly assume these goals while trying to maximize a reward function based on intrinsic and extrinsic motivations. A mapping between motivation and emotion was carried out. So, the agent learned a behavior profile as a training goal. The developed approach was integrated with the Advantage Actor-Critic (A3C) algorithm. Experiments showed that this approach produces behaviors consistent with the objectives given to agents, and has potential for the development of believable virtual characters.

“…By giving the learning algorithm examples of movements and interactions of real people, it can create a model which can interact with the input of the user in the finalized VR application. This process is a solid example (Gillies, 2018), while empirical research underpins the notion of inclusion of agents with a virtual body increasing the user's confidence in the agent's abilities and trustworthiness (Kim et al, 2018).…”

Managing complexity in marketing: from a design Weltanschauung

Marketing is the field of business studies that relates the firm to its wider environment, while its raison d'être is shifting to have wider societal implications beyond the limited dimension of the pure markets, wherein it was originated. The dimension of thought within the mainstream marketing is not adequate for the contemporary evolution of the design-based cyber-physical new economic-order.The current Zeitgeist of sustainability delivers many aspects that go beyond rational economics Weltanschauung, which has occupied marketing-thought by focusing on short time-horizons and the spectrum of the field's applicability based on transactional and mercantile market relations.The dissertation addresses these trends and develops a unified logical framework for marketing in the contemporary era, coined as the "Design Weltanschauung" (DWA), wherein it paves a path to conceptualize the necessary rapprochement between the fields of design and marketing designed as a course-correcting pivot within the field, called the "Design Dominant Logic" (DDL) for an integrative marketing scholarship and practice. DDL evolves marketing beyond its transactionary modus operandi towards a meaning-laden unconcealment of artefacts, which goes beyond the dimensions of a "Unique Sales and Value proposition" towards the notions of "Unique Meaning and Design Propositions", which are based on the co-evolutionary foundations of the contemporary interconnected and globalized cyber-physical-realities. While, marketing originated in a "market(ing)-to" foundation and the latest developments, were founded on a "market(ing)-with" premise, the author has introduced a new foundation of the "marketin(ing)-within", which reflects the contemporary intertwined-ness of marketing with the advancements of technology. Hence, the dissertation has paved a solid path for marketing's shifting raison d'être, wherein marketing is dominated by Artificial intelligence (AI). The dissertation has designed a marketing interpretation for AI integration and also shifted the perceptions of the role of the organizational structural embodiment and ethos for the state of theory and practice for marketers to navigate towards creating meaningladen artefacts' and innovations, wherein customers can self-actualize based on the "requisitevarieties" the firms can offer.The DWA establishes a more embracive logic for marketing replacing the pure economic view that seems to be out of touch with the challenges the firms and societies face.
