The overall efficiency and success of AI solutions depends fundamentally on the quality and effectiveness of the resulting human-AI interaction [1]. Rapid technological adoption often outpaces the careful consideration of ethical challenges and human-centered design principles that are critical for successful implementation and agility. Key stakeholders\u2014including strategic decision-makers, AI engineers<\/a>, and user interface designers\u2014often lack sufficient awareness of the specific pitfalls at the human-AI interface. These multifaceted challenges range from algorithmic opacity and the risk of systemic bias to data privacy concerns, premature automation, eroded human agency, and unclear responsibilities [2\u20135].<\/p>\n\n\n\n

For industrial settings, the research focus often leans heavily towards technical feasibility and performance metrics [6, 7], relegating human and ethical factors to an afterthought. Although numerous frameworks for ethical AI have been proposed, most articulate high-level principles\u2014such as transparency, fairness, non-maleficence, responsibility, and privacy\u2014without offering concrete guidance for implementation [8, 9]. This leaves a persistent operationalization gap between abstract ideals and everyday AI development.<\/p>\n\n\n\n

Efforts to address this gap have led to a growing number of methods and tools, yet these typically target only isolated stages of the development process or specific modalities for addressing ethical AI issues, like summaries, notions, code, and education [9]. Consequently, the landscape remains fragmented, with few approaches considering how different forms of guidance\u2014ranging from conceptual reflection to technical implementation\u2014can interact to support practitioners throughout the entire AI lifecycle.<\/p>\n\n\n\n

In response to this fragmentation, human-centered AI (HCAI) has gained attention as an applied perspective aiming to translate ethical principles into sociotechnical design and development practices [6, 10]. While ethical AI focuses on normative principles and governance, HCAI stresses participation, usability, and the augmentation of human capabilities. Despite their overlap, the two differ in focus: ethical AI defines what should be achieved, HCAI explores how it can be realized. Yet, both continue to struggle with operationalizing these principles in practice.<\/p>\n\n\n\n

tachAId (technical assistance concerning human-centered AI development<\/em>) was developed to address this gap [11]. It is an interactive, web-based self-service advisory tool designed to embed HCAI considerations directly into the technical implementation process. This paper reports on the design principles and qualitative validation study of the tachAId artifact. Through two industrial case studies, it demonstrates how such a tool can begin to bridge the operationalization gap in applied AI ethics, while illuminating the related challenges.<\/p>\n\n\n\n

Operationalizing human-centered AI with tachAId<\/em><\/h2>\n\n\n\n

tachAId originated with the aim of raising awareness about HCAI among diverse stakeholders, guiding their reflection on HCAI principles within their specific project context, and providing actionable guidance, regardless of their initial level of AI or ethics expertise. This section outlines both the theoretical foundations that inform HCAI in practice and the design of tachAId, which operationalizes these principles through interactive, stakeholder-oriented guidance.<\/p>\n\n\n\n

Theoretical foundations: Grounding HCAI in practice<\/h3>\n\n\n\n

Developing and deploying AI necessitates a shift towards HCAI, an approach that emphasizes aligning AI systems with human values, needs, and capabilities to enhance, augment, and empower individuals rather than automate tasks [3, 6, 10]. Achieving HCAI in practice requires navigating key ethical criteria that manifest across the AI lifecycle [8]. Building on frameworks that analyze HCAI configurations in organizational contexts [12], tachAId operationalizes criteria particularly pertinent to applied ethics in industrial settings.<\/p>\n\n\n\n

Human agency and domain knowledge integration<\/h3>\n\n\n\n

A central tenet of HCAI is designing AI systems as tools that support user control, enhance skills, and foster a sense of ownership, preventing deskilling or over-reliance [3, 4, 12]. This involves creating human-in-the-loop systems where humans remain in control and AI acts as a collaborative partner, augmenting capabilities in complex situations. By reinforcing human agency through meaningful involvement, such systems uphold responsibility, trust, fairness, and non-maleficence\u2014ensuring decisions and thereby accountability remain transparent and preventing automation bias or unintended harm [8].<\/p>\n\n\n\n

Effective AI solutions also require actively integrating domain user expertise not only in deployment, but throughout the development lifecycle\u2014from data collection and feature engineering to model validation\u2014ensuring tools are technically sound, practically relevant, and usable. Embedding expertise across stages further promotes beneficence and sustainability by grounding system behavior in contextual understanding and long-term societal benefit rather than short-term performance [8].<\/p>\n\n\n\n

Clarification of responsibilities and processes<\/h3>\n\n\n\n

AI integration introduces ambiguity into existing workflows. A human-centered approach requires defining clear roles, accountabilities, and processes for data management, model training and monitoring, and handling AI failures or unexpected outcomes [12, 13]. This clarity is essential for establishing trust and ensuring safe operation.<\/p>\n\n\n\n

Design and implementation of tachAId<\/em><\/h3>\n\n\n\n

To translate HCAI criteria into a practical and engaging tool, we developed tachAId for the self-guided exploration of HCAI topics, integrating them into the technical steps of AI implementation. It targets stakeholders with diverse roles and expertise\u2014including decision-makers, developers, and researchers\u2014and moves beyond static formats like checklists or white papers by facilitating reflection and learning rather than merely presenting information. Drawing on Hohman et al.\u2019s interactive article affordances [14], we derived five design principles (DPs) that guided tachAId\u2019s creation and structure. See Figure 1<\/strong> for our DPs and Figure 2<\/strong> for a view of tachAId.<\/p>\n\n\n\n

Methodology: A formative evaluation in two industrial cases<\/h2>\n\n\n\n

To evaluate the utility, usability, and effectiveness of tachAId, a qualitative validation study was conducted. The primary goal was to generate actionable feedback for improvement. It was a formative, naturalistic evaluation: formative because findings directly informed the tool\u2019s next design iteration, and naturalistic because participants applied the tool to their real-world projects, increasing ecological validity. For this purpose,tachAId was evaluated in two distinct industrial manufacturing contexts, chosen to represent different points in the AI adoption journey and test the tool\u2019s relevance across varying organizational AI maturity levels and application settings (Fig. 3<\/strong>). In total, three participants with different stakeholder roles were recruited.<\/p>\n\n\n\n
