EXPLORING THE TACTILE MODALITY FOR HMDs

چکیده
Humans commonly are considered to have five separable named senses, called hearing, sight (vision), smell, taste, and touch, providing information about the external world. These senses, their organs, and respective modalities are listed in Table 18-1. The two most dominant senses are sight and hearing. Equipment designers understand human reliance on these two senses and have used them as the basis for most instruments and controls, as would be expected since humans manipulate and receive most feedback from their external environment based on what they see and hear. However, humans have a limited capacity to receive, hold in working memory, and cognitively process information taken from the environment through any particular sensory pathway. For operators of complex or multiple systems processing demands may be so large that the sole reliance on sight and hearing can lead to an overloading of these two sensory channels (Sorkin, 1987; van Veen and van Erp, 2001).

Auditory-visual Interactions
Most displays or other devices designed to communicate information focus on a single sensory modality. This is perhaps a consequence of the fact that most research examining human perceptual capabilities has focused on a single sensory system at a time. However, most events in the natural environment generate physical information affecting multiple sensory modalities. This information is typica...
متن کاملExploring the Relationship Between Modality and Readability Across Different Text Types
With regard to the relationship between the use of modality and readability levels oftexts, 2 opposing views have been raised. The first view endorses direct positiverelationship between modality and readability in the sense that the use of modalityincreases textual understandability. The second view is that the use of modality leadsto an increase in the number of words, resulting in readabilit...
متن کاملA Tactile Sensing System Based on Arrays of Piezoelectric Polymer Transducers
Tactile sensing enables robots to interact safely and effectively with unstructured environments and humans in case of both voluntary and reactive interaction tasks. Focusing on humanoid robots, there is increasing interest in avoiding negative human feelings towards the “entity” [1], enabling robots to interact with humans in more intuitive and meaningful ways [2-4]. This requires designing me...
متن کاملEffects of Vestibular and Tactile Stimulation on Behavioral Disorders due to Sensory Processing Deficiency in 3-13 Years Old Iranian Autistic Children
Objectives: Among the most important problems of autistic children are the behavioral disorders due to sensory processing deficiency, which are typically reflected in behaviors such as impulsivity, attention and concentration disorders, undesirable emotional reactions, sensory seeking in the form of stereotype behaviors, self-injury and self-stimulating. The present study aimed at exploring the...
متن کاملIndependent Attention Mechanisms Control the Activation of Tactile and Visual Working Memory Representations.
Working memory (WM) is limited in capacity, but it is controversial whether these capacity limitations are domain-general or are generated independently within separate modality-specific memory systems. These alternative accounts were tested in bimodal visual/tactile WM tasks. In Experiment 1, participants memorized the locations of simultaneously presented task-relevant visual and tactile stim...
