“…Virtual reality technology is a typical human-machine intelligent interaction. rough the connection of the network, direct dialogue between machines and humans can be realized, which greatly enhances the user's experience [3,21]. However, in the traditional human-machine system, people are regarded as the operators of the system, and they only operate the machines without real interaction.…”

In order to reduce the difficulty of the Internet of Things intelligent environment system to provide users with layout services and optimize the system structure, this paper proposes to design a context-aware service system based on the user interaction mode of the Internet of Things. This article first collected a large amount of data through the literature survey method, which laid a sufficient theoretical foundation for the subsequent research; then, using smart sensors, smart interaction technology, and context awareness methods is employed to design and build a context-aware service system based on the user interaction modality of the Internet of Things; in order to test the performance and effect of the situational awareness system, take the elderly home care behavior as the research object, collect the 28-day home behavior of the elderly as sample data, and divide it into 7-day data, 14-day data, 21-day data, and 28-day data, by adopting rule pruning demand reasoning algorithm and evidence theory algorithm to reason about the service demand of the elderly. Finally, the experimental results show that the rule-pruning-based service demand reasoning algorithm combined with the evidence theory algorithm optimizes the system, which can better perceive the situation of the elderly living alone and can well reason about the elderly’s service demand, which is of great significance for solving the life and safety problems of the elderly.

“…Nowadays it is not only expert developers that program, but people with all levels of expertise carry out various programming-like tasks, from simple configurations of IoT systems in their smart home (Ur et al 2016; Fig. 1 Overview of the contributions of the paper with references to relevant sections Markopoulos et al 2017;Brich et al 2017), to more complex installation and management of technology systems in their work, to more unconventional forms of programming using visual languages (Erwig et al 2017;Akiki et al 2017) (such as Fraunhofer's IoT Programming Language NEPO 5 or Google's Blockly) or domain specific languages, and even assembling ready-programmed components into a final software system as done, e.g., in the IBM's IoT development environment. 6 This is because of the proliferation of simple (abstract, graphical, etc.)…”

Studying human-to-computer bias transference

It is generally agreed that one origin of machine bias is resulting from characteristics within the dataset on which the algorithms are trained, i.e., the data does not warrant a generalized inference. We, however, hypothesize that a different ‘mechanism’ may also be responsible for machine bias, namely that biases may originate from (i) the programmers’ cultural background, including education or line of work, or (ii) the contextual programming environment, including software requirements or developer tools. Combining an experimental and comparative design, we study the effects of cultural and contextual metaphors, and test whether each of these are ‘transferred’ from the programmer to the program, thus constituting a machine bias. Our results show that (i) cultural metaphors influence the programmer’s choices and (ii) contextual metaphors induced through priming can be used to moderate or exacerbate the effects of the cultural metaphors. Our studies are purposely performed with users of varying educational backgrounds and programming skills stretching from novice to proficient.

“…Blockly's paradigm is similar to jigsaw puzzles, which researchers introduced and evaluated in the area of end-user development [98,99]. We also used jigsaw puzzles as the visual notation for Visual Simple Transformations (ViSiT), which is an approach that empowers end-users to wire together previously incompatible IoT objects [100]. The previous work showed that end-users perceive visual interlocking blocks to be usable and learnable.…”

“…Another important criterion is also the usability of Blockly's visual paradigm that constitutes interlocking blocks. A similar type of blocks, namely jigsaw puzzles, proved to be understandable by end-users in a previous work that we did on end-user development for IoT [100]. In that work, we assessed our puzzle notation based on the cognitive dimensions framework and with end-users.…”
