Touch sensing can help robots understand their surrounding environment, and in particular the objects they interact with. To this end, roboticists have, in the last few decades, developed several tactile sensing solutions, extensively reported in the literature. Research into interpreting the conveyed tactile information has also started to attract increasing attention in recent years. However,...

Supplementing the presentation of colors with tactile displays has yet to be developed. This study used Russell’s affective plane to investigate the association between the rainbow colors and vibrotactile and variable-friction stimuli presented as tactile displays. A user study indicated that high-frequency and rhythmical tactile stimuli that were perceived as arousing were suitable for present...

This study investigated the neural mechanisms implicated in tactile perception using a discrimination task. We also investigated the influence of the type of presentation on the subject's uncertainty. The stimuli varied across four levels of roughness and were presented using a pure/mixed block design. We used an oddball paradigm with three target stimuli varying in the level of roughness, and ...

Aim: To investigate students’ perceptions of using e-models in an inquiry-based curriculum. Approach: 52 second-year dental students completed a preand post-test questionnaire relating to their perceptions of e-models and their use in inquiry-based learning. The pre-test occurred prior to any learning with e-models. The follow-up survey was conducted after one year's experience of using e-model...

The study of the brain bases for normal musical listening has advanced greatly in the last 30 years. The evidence from basic and clinical neuroscience suggests that listening to music involves many cognitive components with distinct brain substrates. Using patient cases reported in the literature, we develop an approach for understanding disordered musical listening that is based on the systema...

Affective touch plays an important role in children's social interaction and is involved in shaping the development of the social brain. The positive affective component of touch is thought to be conveyed via a group of unmyelinated, low-threshold mechanoreceptive afferents, known as C-tactile fibers that are optimally activated by gentle, slow, stroking touch. Touch targeting these C-tactile f...

Tactile stimuli on moving limbs are typically attenuated during reach planning and execution. This phenomenon has been related to internal forward models that predict the sensory consequences of a movement. Tactile suppression is considered to occur due to a match between the actual and predicted sensory consequences of a movement, which might free capacities to process novel or task-relevant s...

Ultrasound mid-air haptic (UMH) devices can remotely render vibrotactile shapes on the skin of unequipped users, e.g., to draw icons or virtual object shapes. Spatio-temporal modulation (STM), state-of-the-art UMH shape rendering method, provides large freedom in design and produces strongest possible stimuli for this technology. Yet, STM are often reported be blurry, complicating identificatio...

Perceptual completion is a fundamental perceptual function serving to maintain robust perception against noise. For example, we can perceive vivid experience of motion even for the discrete inputs across time and space (apparent motion: AM). In vision, stimuli irrelevant AM are suppressed smooth along trajectory where no physical applied. We investigated whether such masking induced by dynamic ...
