AI has become ubiquitous in our society, accelerated by the speed of the development of machine learning algorithms and voice and facial recognition technologies used in our everyday lives. Furthermore, AI-enhanced technologies and tools are no strangers in the field of education. It is more evident that it is important to prepare K-12 population o...

This study develops an information-input interface in which a visual stimulus targeted by a user’s eye gaze is identified based on the pupillary light reflex to periodic luminance modulations of the object. Experiment 1 examines how pupil size changes in response to periodic luminance modulation of visual stimuli, and the results are used to develo...

... This is expected as there is presently no K-12 AI curriculum or lessons in Africa, particularly Nigeria that addresses the ethical aspects of AI [68]. Although, there is already an AI ethics curriculum taught in other contexts [59], Nigeria may need to create its own contextually sensitive AI ethical curriculum, which is similar to the approach adopted for the Japanese context [19]. Besides, human-machine interaction is new, especially in the context under study, therefore, ethical dilemma by both teachers and student may be prevalent, which may in turn affected the lack of cognitive competences and AI content regarding ethics. ...
... Hybrid BCI can improve the classification accuracy, increase the number of commands, and shorten the detection time of the BCI system by combining two or more patterns (at least one of which is a brain signal) (Hong and Jawad, 2017). Recently, pupillary responses (PR), such as the pupillary light reflex, have been used as the second pattern in addition to EEG due to the low user burden, non-invasiveness, and no need for training (Muto et al., 2020). Pupil diameter changes steadily with the illuminance of the observed object to regulate the amount of light entering the eye (Crawford, 1936;Woodhouse, 1975;Woodhouse and Campbell, 1975), and the modulation frequency of PR is synchronized with the luminance-modulation frequency of the visual stimulus. ...
