“…For each cue, these requirements were compared (TABLE I). In our previous study, we demonstrated that an upper limb motion can be induced by applying the illusory pulling cue to the user's finger tips using non-grounded vibrators [32]. Therefore, all requirements in Table I can be achieved using illusory pulling cues.…”

A white cane is conventionally used by visually impaired persons to assist their mobility. To learn its proper operation, training by an orientation & mobility specialist is necessary. However, because the number of specialists is limited, visually impaired persons often do not receive sufficient training. To rectify this issue, a training environment in which the visually impaired can train independently is required. This paper proposes a training system that enables the visually impaired to learn white cane techniques using illusory pulling cues. Specifically, in the white cane touch technique, which is a basic white cane technique, a system that targets the swing width of the white cane is presented by illusory pulling cues. To verify the efficacy of the system, a prototype was implemented and evaluated via user tests. The results confirmed that the error of the swing width of the white cane decreased following use of the proposed system. The proposed system will contribute to the development of the mobility of the visually impaired by enabling them to train with the white cane independently and spontaneously, thereby reducing the workload of specialists.

“…The real challenge is faced in capturing the hidden connotations when such items are translated to, for instance, Arabic. The notion of "translational force" postulates that certain words, by virtue of their flexibility and dynamism, carry a unique communicative ability and are hence, open to translation confusion (Lee et al, 2019;Tanabe et al, 2020). The verbs 'come' and 'go', among a few others, in the English language exemplify this translational force, stemming from the wide range of polysemous meanings associated with them.…”

This study delves into the translational challenges Arabic translators face in preserving the dynamism and multifaceted meanings of ‘come’ and ‘go’ phrasal verbs during translation using machine tools. Though existing literature has focused on linguistic and cultural equivalence, the ‘translational force’ of specific words is still under-researched. The aim of this study is to verify the accuracy of the output across tools, and to conclude how effective these applications were in the given language pair. The study adopts a mixed methods approach with a survey used to identify the most frequently used machine tools for translation by 27 learners of Translation Studies at Shaqra University, Saudi Arabia. Thereafter, a set of frequently used phrasal verbs in English that use the root verbs ‘come’ and ‘go’ were translated by a convenience sample of 27 final year students of translation as well as by using the popular and free translation tools in the English-Arabic language pair. Results indicated that Saudi students enrolled in translation studies used MateCAT, Google Translate, Reverso to a limited extent, but relied more on online dictionaries for translation to and from English. In addition to this, translation of English phrasal verbs was found to be most accurate in MateCat and there too, accuracy in back translation was found to be more accurate in the case of the phrasal verbs formed with ‘come’ at the root than with ‘go’ verb. Finally, it was found that the translation students preferred ‘soft tools’ like English movies for learning, recall, and use of English phrasal verbs in practice. This study is expected to provide a deeper understanding of the concept of "translational force" and its implications for translating dynamic words in the English-Arabic language pair in the realm of machine-based translation tools.

“…Although the mechanism by which the illusion occurs is not entirely clear, previous researchers have discussed the role of mechanoreceptors [8], the influence of skin deformation [10], and cerebral functions [11] in relation to this illusion. Typical applications of the illusory directional sensation were force feedback [12], navigation [13], [14], and motion guidance for upper-limb [15], [16]. We have specifically focused on the utility of motion guidance and have developed a training system utilizing this illusion for white-cane orientation in patients with visual impairment [17].…”

Illusory directional sensations are generated through asymmetric vibrations applied to the fingertips and have been utilized to induce upper-limb motions in the rehabilitation and training of patients with visual impairment. However, its effects on motor control remain unclear. This study aimed to verify the effects of illusory directional sensations on wrist motion. We conducted objective and subjective evaluations of wrist motion during a motor task, while inducing an illusory directional sensation that was congruent or incongruent with wrist motion. We found that, when motion and illusory directional sensations were congruent, the sense of agency for motion decreased. This indicates an induction sensation of the hand being moved by the illusion. Interestingly, although no physical force was applied to the hand, the angular velocity of the wrist was higher in the congruent condition than that in the no-stimulation condition. The angular velocity of the wrist and electromyography signals of the agonist muscles were weakly positively correlated, suggesting that the participants may have increased their wrist velocity. In other words, the congruence between the direction of motion and illusory directional sensation induced the sensation of the hand being moved, even though the participants' wristmotion velocity increased. This phenomenon can be explained by the discrepancy between the sensation of active motion predicted by the efferent copy, and that of actual motion caused by the addition of the illusion. The findings of this study can guide the design of novel rehabilitation methods.
