Design Goals for End-User Development of Robot-Assisted Physical Training Activities: A Participatory Design Study

Programming robots presents significant challenges, including high costs, extensive time commitments and steep learning curves, particularly for individuals lacking technical background in engineering. These barriers have been partially mitigated by the emergence of end-user development methodologies. Yet existing approaches often fall short in equipping users with the necessary software engineering competencies to develop comprehensive robot behaviors or to effectively maintain and re-purpose their creations. In this paper, we introduce a novel end-user development approach designed to empower physical therapists to independently specify robot-assisted physical training exercises, eliminating the need for robotics experts' intervention. Our approach is based on a set of design goals obtained through a participatory design study with experts in the field. It utilizes a textual domain-specific language (DSL) that enables users to define expected robot behaviors through Behaviour-Driven Development (BDD) scenarios. This paper discusses key themes, design objectives, and the evolution of requirements that emerged from an evaluative workshop.

Defining complexity in anaesthesia: description and validation of the Oxford Anaesthetic Complexity (OxAnCo) score.

Increasing demand for surgery and anaesthesia has created an imperative to manage anaesthetic workforce and caseload. This may include changes to distribution of cases amongst anaesthetists of different grades, including non-physician anaesthetists. To achieve this safely, an assessment of case complexity is essential. We present a novel system for scoring complexity of cases in anaesthesia, the Oxford Anaesthetic Complexity score. This integrates patient, anaesthetic, surgical and systems factors, and is different from assessments of risk. We adopted an end-user development approach to the design of the score, and validated it using a dataset of anaesthetic cases. Across 688 cases, the median (IQR [range]) complexity score was 19 (17-22 [15-33]). Cases requiring a consultant anaesthetist had a significantly higher median (IQR [range]) score than those requiring a senior trainee at 22 (20-25 [15-33]) vs. 19(17-21 [15-28]), p < 0.001. Cases undertaken in a tertiary acute hospital had a significantly higher score than those in a district general hospital, the median (IQR [range]) scores being 20 (17-22 [15-33]) vs. 17 (16-19 [17-28]), p < 0.001. Receiver-operating characteristic analysis showed good prediction of complexity sufficient to require a consultant anaesthetist, with area under the curve of 0.84. Any rise in complexity above baseline (score > 15) was strongly predictive of a case too complex for a junior trainee (positive predictive value 0.93). The Oxford Anaesthetic Complexity score can be used to match cases to different grades of anaesthetist, and can help in defining cases appropriate for the expanding non-physician anaesthetist workforce.

Context-Aware End-User Development Review

Context-aware application development frameworks enable context management and environment adaptation to automatize people’s activities. New technologies such as 5G and the Internet of Things (IoT) increase environment context (from devices/services), making functionalities available to augment context-aware applications. The result is an increased deployment of context-aware applications to support end-users in everyday activities. However, developing applications in context-aware frameworks involve diverse technologies, so that it traditionally involves software experts. In general, context-aware applications are limited in terms of personalization for end-users. They include configurations to personalize applications, but non-software experts can only change some of these configurations. Nowadays, advances in human–computer interaction provide techniques/metaphors to approach non-software experts. One approach is end-user development (EUD)—a set of activities and development tools that considers non-software experts as application builders. In this paper, we present our analysis of existing EUD approaches for building context-aware applications. We present a literature review of 37 screened papers obtained from research databases. This review aims to identify the methods, techniques, and tools proposed to build context-aware applications. Specifically, we reviewed EUD building techniques and implementations. Building techniques include metaphors/interaction styles proposed for application specification, composition, and testing. The implementations include a specification method to integrate and process context on the target application platforms. We also present the adoption trend and challenges of context-aware end-user development.

Integrated Monitoring System to Improve the Procurement Process through Provider with an End-User Development Approach (Case Study: XXX Institute)

This study aims to identify problems in procurement activities through providers at XXX Institute and to provide solutions to improve the procurement process through providers with an integrated system design to monitor the procurement process at XXX Institute. XXX Institute under the authority of Government that services in education and training. XXX institute are required to follow the procedures and rules set by the government to achieve the procurement objectives as stipulated in Presidential Regulation No. 16 Tahun 2018. Based on the identification problems, some obstacles is still existing in the procurement activities at XXX Institute due to negligence of procurement parties. An integrated monitoring system is needed for procurement parties to monitor the procurement process, so that the impact of procurement inconsistencies can be systematically resolved. In this research, the theories uses the PIECES Framework and the FAST method developed by Whitten and Bentley (2007) to identify problems in the system and create a system design to overcome these problems. The system design uses the end-user development system design process. According to Marshall B. Romney (2018) end-user development is a computer-based application which is the users can manage and develop the system. The result of the system design is a system to monitor every process of procuring goods or services at XXX Institute.

From smart objects to smart experiences: An end-user development approach

Abstract The growing availability of smart objects is stimulating researchers to investigate the Internet of Things (IoT) phenomenon from different perspectives. The potential of this technology is evident in different domains. In Cultural Heritage (CH), it may enhance access to CH collections, in order to ensure a more engaging visit experience and to increase the appropriation of CH content by visitors. So far, research on IoT has primarily focused on technical features of smart objects (e.g., how to program sensors and actuators), while there are very few approaches trying to facilitate the adoption of such a technology by end users. This lack limits the social and practical benefits of IoT; it creates barriers in all those usage scenarios where people would like to define the behavior of smart objects but they might not have the required programming skills. This is becoming evident in CH sites, where different stakeholders would benefit from managing ecosystems of interoperable smart objects to create enhanced visit experiences. This article presents a visual composition paradigm that allows non-programmers to synchronize the behavior of smart objects, thus determining more engaging user experiences. It discusses how the paradigm suites the need of curators and guides of CH sites to define smart visit experiences through which visitors can acquire CH content by interacting with the surrounding environment and the smart objects included in it. A serious game designed with professional guides of CH sites is used as a case study to show the potential of the presented approach.

An example is worth a thousand words: Creating graphical modelling environments by example

Domain-specific languages (DSLs) are heavily used in model-driven and end-user development approaches. Compared to general-purpose languages, DSLs present numerous benefits like powerful domain-specific primitives, an intuitive syntax for domain experts, and the possibility of advanced code generation for narrow domains. While a graphical syntax is sometimes desired for a DSL, constructing graphical modelling environments is a costly and highly technical task. This relegates domain experts to a rather passive role in their development and hinders a wider adoption of graphical DSLs. Our aim is achieving a simpler DSL construction process where domain experts can contribute actively. For this purpose, we propose an example-based technique for the automatic generation of modelling environments for graphical DSLs. This way, starting from examples of the DSL likely provided by domain experts using drawing tools like yED, our system synthesizes a graphical modelling environment that mimics the syntax of the provided examples. This includes a meta-model for the abstract syntax of the DSL and a graphical concrete syntax supporting spatial relationships like containment and adjacency. Our system, called metaBUP, is implemented as an Eclipse plug-in. In this paper, we demonstrate its usage on a running example in the home networking domain and evaluate its suitability for the construction of graphical modelling environments by means of a user study.

Visual Simple Transformations

Empowering end-users to wire Internet of Things (IoT) objects (things and services) together would allow them to more easily conceive and realize interesting IoT solutions. A challenge lies in devising a simple end-user development approach to support the specification of transformations, which can bridge the mismatch in the data being exchanged among IoT objects. To tackle this challenge, we present Visual Simple Transformations (ViSiT) as an approach that allows end-users to use a jigsaw puzzle metaphor for specifying transformations that are automatically converted into underlying executable workflows. ViSiT is explained by presenting meta-models and an architecture for implementing a system of connected IoT objects. A tool is provided for supporting end-users in visually developing and testing transformations. Another tool is also provided for allowing software developers to modify, if they wish, a transformation's underlying implementation. This work was evaluated from a technical perspective by developing transformations and measuring ViSiT's efficiency and scalability and by constructing an example application to show ViSiT's practicality. A study was conducted to evaluate this work from an end-user perspective, and its results showed positive indications of perceived usability, learnability, and the ability to conceive real-life scenarios for ViSiT.

TAPAS: A tangible End-User Development tool supporting the repurposing of Pervasive Displays

These days we are witnessing a spread of many new digital systems in public spaces featuring easy to use and engaging interaction modalities, such as multi-touch, gestures, tangible, and voice. This new user-centered paradigm — known as the NUI — aims to provide a more natural and rich experience to end users; this supports its adoption in many ubiquitous domains, as it naturally holds for Pervasive Displays: these systems are composed of variously-sized displays and support many-to-many interactions with the same public screens at the same time. Due to their public and moderated nature, users need an easy way of adapting them to heterogeneous usage contexts in order to support their long-term adoption. In this paper, we propose an End-User Development approach to this problem introducing TAPAS, a system that combines a tangible interaction with a puzzle metaphor, allowing users to create workflows on a Pervasive Display to satisfy their needs; its design and visual syntax stem from a study we carried out with designers, whose findings are also part of this work. We then carried out a preliminary evaluation of our system with second year university students and interaction designers, gathering useful feedback to improve TAPAS and employ it in many other domains.

Multi-Level Adaptation in End-User Development of 3D Virtual Chemistry Experiments

Multi-level adaptation in end-user development (EUD) is an effective way to enable non-technical end users such as educators to gradually introduce more functionality with increasing complexity to 3D virtual learning environments developed by themselves using EUD approaches. Parameterization, integration, and extension are three levels of adaptation ranging from straightforward to complex in terms of what end users have to understand in order to develop functional software applications, all within reach of end users without special training on programming. A 3D educational application EUD system prototype, iVirtualWorld, has been expanded to support 3D virtual chemistry experiments generation using these three levels of EUD adaptation. An evaluation has been conducted on 18 participants from the education domain, and the results confirmed ease-of-learn, ease-of-use, and usefulness of this solution. Contributions of this paper are 1) a paradigm for applying EUD technologies in 3D virtual learning environment creation; 2) an easy-to-use tool for educators to build customized virtual chemistry experiments; and 3) empirical assessment data for the multi-level adaptation solution.
