Joint attention in autism: A narrative review of assessment techniques from behavioral observation to artificial intelligence
Joint attention (JA), the shared focus between two individuals on an object or event, plays a pivotal role in social communication, cognitive development, and language acquisition during early childhood. However, JA is frequently impaired in children with autism spectrum disorder (ASD), highlighting the need for precise assessment to support early diagnosis and intervention. This narrative review explores the evolution of JA assessment methods, tracing the shift from human-mediated techniques to technology-driven approaches, including artificial intelligence (AI). The study analyzes research indexed in major bibliographic databases between 2002 and 2024, categorizing findings into human-mediated and technology-assisted methods. Key aspects such as target populations, data collection processes, and validation strategies are examined. By highlighting the strengths and limitations of existing approaches, the review identifies future research directions that can advance JA assessment and inform early intervention strategies, ultimately benefiting children with ASD and their families.

This section aims to uncover the methods and techniques that rely on non-technological (psychologically based) means to evaluate an individual's ability to engage in JA behaviors. These methods typically involve direct observation of the individual's behavior in structured or unstructured settings, often using standardized tasks or tasks designed by the assessor (Charman, 2003). These assessments are usually administered in person by trained professionals, such as psychologists, speech therapists, or educators, and may involve interaction with the individual being assessed and/or their caregivers (Charman, 2003; Mundy et al., 2003). In most cases, the assessment sessions are video recorded, allowing the assessor to review the footage post-assessment to analyze behaviors and generate an evaluation score.

Advancements in technology, particularly in computer graphics, have prompted researchers to transition from traditional methods to computer-based technological approaches for assessing JA (Jyoti et al., 2020). Furthermore, the progress in human-computer interaction has facilitated enhanced communication between humans and computers, leading to the development of technologies such as eye-tracking, face recognition, VR, and robotics (Zhang et al., 2018). As a result, recent research has predominantly focused on integrating these technologies for the task of JA assessment. This section delves into the various technology-based approaches for JA assessment, including eye-tracking, VR, robotic systems, and computer vision. A total of 43 primary studies were identified in this category, with 27 focusing on eye-tracking technology.

Studies using Eye-Tracking Technology
Automated JA Detection with AI
Zhang et al. (2018) proposed a vision-based system that uses an RGB camera and Kinect sensor to detect JA automatically. The key components of their system include hand gesture recognition, face detection, and eye gaze tracking, which are used to measure the essential elements of JA – the adult’s pointing/gaze, eye contact between the adult and child, and the child’s gaze following the adult’s to the target object. The researchers evaluated their system by testing it on eight non-ASD adults and found that it could effectively detect JA with good accuracy, except for one case where the child’s small face size led to poor eye gaze detection. Similarly, Prakash et al. (2023) assessed a broader range of behaviors and skills in children with ASD, including JA using computer vision. In particular, they developed two models – one to recognize when a child follows the gaze direction of the therapist to establish JA, and another to detect when the child points a finger to respond to the therapist’s verbal questions and establish JA. Another method proposed by Ko et al. (2023) focused on JA tasks, video data acquisition, and a deep learning (DL) model to detect and assess symptoms of ASD.
This section discusses new directions that have yet to be explored in the assessment of JA. These directions are derived from the insights, observations, and open research issues identified in existing approaches.
| Approach | Key Limitations |
|---|---|
| Human-mediated | Subjectivity, inter-rater variability, limited temporal resolution |
| Technology-assisted | Reduced social richness in some setups; cost and accessibility |
| Combined | Increased methodological and analytical complexity |
The Power of Multimodal AI for Comprehensive JA Assessment
One promising direction in JA assessment is the fusion of multimodal data, which involves combining behavioral observations with visual, audio, and eye-tracking data. This multimodal approach presents a more robust, dense, and complete representation of behavior for several reasons. Firstly, different sensing technologies excel at capturing particular aspects of a phenomenon. For instance, visual data can provide detailed information on facial expressions and body movements, audio data can capture nuances in vocal intonations and speech patterns, and eye-tracking data can precisely measure gaze direction and fixation durations. Secondly, multimodal sensing captures a broader range of information, effectively overcoming the limitations inherent in relying on a single sensing modality (Varghese et al., 2021). Incorporating AI into this multimodal approach demonstrates remarkable potential in utilizing a wide array of data to solve real-world problems, particularly in the context of JA assessment (Porayska-Pomsta et al.., 2018).
