2. Introduction

When we talk about artificial intelligence (AI), most people think of machines that process data, solve complex problems, or automate tasks. In medicine, this translates into algorithms that read x-rays, predict cardiovascular risks, or help optimize patient flow. But there is a new field emerging powerfully—one that doesn’t just analyze what we are, but what we feel: emotional artificial intelligence.

Can a machine interpret distress in how we write a message? Recognize a depressive episode before the patient confesses it? Modify its tone and content to adapt to the user’s emotional state?

These questions, which until recently seemed like science fiction, already have practical answers in multiple clinical applications. We are witnessing the rise of artificial systems designed to detect, model, and respond to human emotions—without having emotions themselves, but with an increasing capacity to simulate emotional understanding.

It is crucial to distinguish between feeling empathy and simulating it. Feeling empathy involves an authentic emotional experience, an inner resonance with another’s suffering—something unique to the human condition. Simulating empathy, on the other hand, generates a response that seems compassionate without an inner experience of the emotion. Emotional AI systems fall into this second category: they respond with carefully designed phrases, modulated tone, and adapted content, but without any consciousness to understand what they are expressing.

This distinction is not trivial. It has profound ethical and therapeutic implications, as emphasized by medical ethicists like Pellegrino and Thomasma (1993), who argue that clinical relationships require moral authenticity—something that cannot be replicated by technological simulations, especially in health contexts where emotional containment is essential to patient recovery.

This technology, known as Artificial Emotional Intelligence or Affective Computing, represents a radical advance. It is not limited to interpreting clinical signs, but is trained to interpret the emotional dimension of human experience. Its foundation is not empathy, but pattern recognition: voice inflections, microexpressions, typing rhythm, pauses, omissions, sleep patterns, and more. With these, it builds functional emotional models.

In medicine, this can change everything.

Because pain is not always spoken. Therapeutic abandonment often has emotional roots. And the best diagnostic tool is not always a blood test, but the ability to listen beyond words.

From virtual assistants that adapt their language when they detect frustration to remote monitoring platforms that predict mental health crises, emotional AI is already being implemented—silently but effectively—in clinics, hospitals, mental health apps, and chronic care programs.

And here the ground becomes fascinating… and delicate.

Because if a machine can know how we feel, who guarantees it will use that information for our well-being and not to manipulate us? If a digital system intervenes when it detects sadness, is it offering help or invading privacy? And what about consent, privacy, and the dignity of those who no longer have emotionally sensor-free spaces?

Even more: if an algorithm can simulate emotional support, can it replace human presence? And do we want to live in a world where compassion is emulated by code?

This article aims to explore that threshold. We will define what emotional AI is, describe its main health applications—from the detection of mental disorders to the improvement of therapeutic adherence—and analyze its ethical, clinical, and philosophical boundaries.

Because in the near future, we will no longer ask whether AI can diagnose pneumonia.

We will ask: Can this AI understand my sadness? Can it respond in a way that makes me feel accompanied? And do I want it to?

3. What is Artificial Emotional Intelligence?

Artificial Emotional Intelligence, also known as Affective Computing, refers to the field of artificial intelligence focused on enabling systems to detect, interpret, and simulate human emotional responses. Coined and popularized by Rosalind Picard at the MIT Media Lab in the 1990s, this discipline has since evolved into a powerful domain with clinical, commercial, and social applications.

Unlike traditional AI—focused on structured data, logic, and computation—emotional AI works with ambiguous, imprecise, and highly contextual data: facial expressions, voice tone, body language, language use, typing rhythm, and more. From these, systems derive inferences about the user’s emotional state.

These systems do not feel—but they can convincingly mimic the act of feeling. Using computational emotion models—such as Plutchik’s wheel of emotions or Russell’s circumplex model—they classify emotional states in real time and adapt their responses accordingly. For example, an application might detect signs of anxiety in a user’s input and modify its interface or dialogue to soothe, guide, or emotionally contain the person.

In the healthcare setting, emotional AI offers a twofold promise: it allows a richer understanding of patients’ emotional states and enables tailored responses that enhance adherence, trust, and therapeutic outcomes. However, it also presents a critical risk: responses perceived as manipulative, shallow, or invasive could erode the patient’s trust.

As this technology continues to evolve, clinicians must learn not only how it works but also when and how it should be used—balancing its capacity to augment care with the imperative to preserve human dignity and emotional authenticity.

4. Clinical Applications of Emotional AI in Healthcare

The implementation of emotional artificial intelligence in healthcare is no longer theoretical—it is a rapidly growing reality. Hospitals, startups, and public health systems are integrating emotionally aware AI into various stages of the care continuum. Four primary areas are emerging: mental health, therapeutic adherence, telehealth consultations, and emotional support in chronic illness.

In the field of mental health, emotionally intelligent chatbots such as Woebot and Wysa have gained prominence. These tools use natural language processing (NLP) algorithms to engage in automated conversations that recognize emotional cues like hopelessness, anger, anxiety, or suicidal ideation. Their responses incorporate cognitive behavioral therapy (CBT) techniques and, when necessary, suggest connecting with a human professional. Clinical trials have shown promising outcomes in reducing symptoms of mild-to-moderate depression, especially among digitally literate youth populations.

Therapeutic adherence is another promising area. Applications like AiCure and Wellth leverage facial recognition and voice tone analysis through smartphone cameras to confirm medication intake. These tools also assess emotional signals—such as gaze aversion or flat affect—to infer motivational barriers to treatment. In response, they adjust communication tone, reinforce positive behaviors, or alert caregivers to signs of non-compliance. These systems function as hybrid agents: technical monitors and emotional coaches.

In remote care settings, emotional AI has been integrated into telehealth platforms. During video consultations, the system analyzes facial expressions, speech cadence, and silence intervals to flag signs of distress, fatigue, or emotional discomfort. These insights augment digital semiology, helping clinicians detect issues that patients may not verbalize—thus enabling more sensitive, person-centered interventions.

For patients with chronic illnesses—such as cancer, COPD, or chronic pain—emotional AI assistants provide continuous support between clinical visits. These systems adapt the frequency, tone, and complexity of their messages based on detected emotional states. If signs of persistent sadness arise, they reduce cognitive load and offer reassurance. If emotional resilience improves, they promote more active self-care routines. These adaptive algorithms seek to emotionally sustain the patient’s engagement over time.

Together, these applications highlight that emotional AI is not a novelty—it is an emerging pillar of personalized medicine. Its potential lies in enhancing the therapeutic bond, anticipating emotional crises, and supporting adherence in ways that conventional technologies cannot. Still, its use must be paired with rigorous ethical safeguards, clinical oversight, and a deep respect for emotional privacy. Because while AI can interpret feelings, it does not yet understand suffering. And that distinction remains essential.

5. Ethical Challenges and Dilemmas in Implementing Emotional AI

The implementation of emotional artificial intelligence in clinical practice raises a wide array of ethical questions and practical challenges that go far beyond technology. As AI systems become increasingly capable of detecting and simulating emotional responses, fundamental issues arise regarding consent, confidentiality, autonomy, and the authenticity of the therapeutic relationship.

One of the first challenges is informed consent. Many patients do not realize that behind a friendly interface lies a system that analyzes their voice tone, pauses, word choices, and even facial expressions in real time. Should each emotional detection mechanism be explained in detail? How can we ensure that users explicitly consent to the analysis of their emotions, especially when this often occurs in the background? These issues are particularly delicate in mental health, where emotional vulnerability is a central component of the therapeutic bond.

Another major dilemma is affective privacy. Emotional data, although not always biomedical, are deeply personal. The recording of sadness, frustration, or anxiety patterns—when stored, processed, and potentially shared—requires protection standards even higher than current norms. Who has access to this information? Can an insurance company use it to adjust premiums? Does an employer have the right to know whether an employee has interacted with an emotional AI on a wellness platform?

Questions also arise about the authenticity of the therapeutic bond. If an automated system can generate empathetic responses that soothe, support, and guide, what does that mean for the role of the human professional? Is there a risk that patients may prefer algorithmic interaction due to its immediate availability and lack of judgment? And how does this affect long-term trust-building in the physician-patient relationship?

From a humanistic psychotherapy perspective, the therapeutic relationship is not solely based on the utility of the response, but on the genuine presence of another human being—someone who not only interprets what one feels but also resonates emotionally with that experience. Carl Rogers, for instance, argued that congruence, unconditional positive regard, and real empathy were necessary conditions for psychological change. Emotional AI may simulate these conditions, but it cannot live them—raising questions about the depth and sustainability of the bond it creates.

Narrative medicine, likewise, stresses the importance of actively listening to a patient’s story as a co-construction of meaning. In this approach, the personal narrative is not just clinical data, but a pathway to understanding human suffering. If the interlocutor is a system with no history, no body, and no embodied experience, can it truly participate in that narrative process—or is it merely acting as a technical mirror?

These disciplines remind us that the therapeutic value of a relationship goes beyond the effectiveness of a response: it lies in the ability to hold another’s pain through meaningful human presence—something that, at least for now, machines cannot authentically replicate.

Added to this is the growing concern about algorithmic emotional manipulation. In some cases, systems may be programmed with commercial intentions, generating suggestions or content designed to trigger specific emotional responses. If a system detects mild anxiety and recommends an app, product, or intervention that has been sponsored, who oversees the ethics behind that suggestion? What accountability framework exists when emotional comfort becomes a vehicle for monetization?

Lastly, there is a structural dilemma: emotional technological dependency. Among vulnerable populations—such as the elderly, socially isolated individuals, or patients with mental health disorders—emotional AI can become their primary emotional connection. Are we ready for a society where emotional support is delegated to machines? What effects will this have on community mental health, perceptions of loneliness, or the humanization of care?

These challenges require a multisectoral response: regulators must define clear normative frameworks; healthcare institutions must establish ethical implementation protocols; clinicians must uphold human judgment as the core of care; and developers must commit to explicit bioethical standards. Because while emotional AI can be a powerful tool, its unreflective use may gradually erode the very foundation of medicine: respect for the other’s emotional dignity.

As medical philosopher Edmund Pellegrino reminds us, “medical care can never be reduced to technique; it always involves a moral act in which human suffering is approached with responsibility” (Pellegrino & Thomasma, 1993). This warning compels us to remember that even the most sophisticated innovations must remain subordinate to a deeper ethical imperative: to protect the human encounter—not replace it. Emotional AI, while useful, cannot carry that ethical mantle on its own. It requires human mediators who are conscious, critical, and committed.
