“…With veridical multisensory information, these mechanisms appear to enhance perception accuracy and reaction time (Deiderich, 1995), as well as modulate ongoing cognitive processes (Schroeder & Foxe, 2005) while improving workload performance and SA (Wickens & Holland, 1999). By exploiting this cortical crossmodal integration (Calvert, 2001), we and other researchers have shown that individuals with sensory loss due to artificial restrictions, disease, congenital defect, or injury can use sensory substitution interfaces to exploit this inherent plasticity of the brain and nervous system for both long term and short term anatomical and functional remapping of sensory data (Walcott & Langdon, 2001;Ptito, Moesgaard, Gjedde & Kupers, 2005;Kaczmarek, Bach-y-Rita, Tompkins & Webster, 1985) and improvement in SA (Raj, Kass, & Perry, 2000;Saunders, Hill & Franklin, 1981). Recent brain imaging studies have confirmed crossmodal modulation of activity across different sensory cortices that varies depending on whether multiple sensory channels provide congruent information or incongruent information (Johnson & Zatorre, 2005;Jones & Callan, 2003;Fort, et al, 2002;Laurienti, et al, 2002).…”

During year one of the Anthro-Centric Multisensory Interface Vision Augmentation/Substitution (ACMI-VAS) project, the research team developed an integrated system that can substitute tactile stimulation for visual stimulation to mimic the function of the retina. The ACMI-VAS concept uses a video camera connection to, or data from, a computer to represent, tactually, high resolution narrow field, mid resolution wider field and low resolution 360 degree visual information simultaneously. We will complete the testbed hardware and software in year two of the project and complete a experimental protocol to test the usefulness of the integrated system against a single tactile display for those (military and civilian) with profound blindness. Tasks will include reading, visual acuity, web browser navigation, walking an obstacle course and identifying colors. 15.

Cognitive Infocommunications (CogInfoCom) is an emerging discipline that investigates synergies between infocommunications and the cognitive sciences, with the goal of creating engineering applications in which systems with various levels of cognitive capability are enabled to work together more effectively. While infocommunications deals with the error-free encoding, transmission and decoding of raw data, CogInfoCom aims to transmit information at a higher, conceptual level in a way that appeals to the receiver's cognitive capabilities. Thus, CogInfoCom may have implications for a wide variety of fields in the future, including virtual reality, 3D Internet and Internet of Things. In this paper, we provide a brief, application-oriented overview of the existing background of CogInfoCom, and outline future perspectives for the field.

“…Initial investigations with tactile displays explored their potential to compensate for sensory loss or impairment [1]. For example, sensory substitution devices have been developed to assist people with impaired vision [1], [7], hearing [8] or balance sense [9]. Unlike sensory substitution, which translates the form of one modality into the form of another; sensory augmentation adds new synthesized information to an existing sensory channel.…”

Sensory augmentation operates by synthesizing new information then displaying it through an existing sensory channel and can be used to help people with impaired sensing or to assist in tasks where sensory information is limited or sparse, for example, when navigating in a low visibility environment. This paper presents the design of a 2nd generation head-mounted vibrotactile interface as a sensory augmentation prototype designed to present navigation commands that are intuitive, informative, and minimize information overload. We describe an experiment in a structured environment in which the user navigates along a virtual wall whilst the position and orientation of the user's head is tracked in real time by a motion capture system. Navigation commands in the form of vibrotactile feedback are presented according to the user's distance from the virtual wall and their head orientation. We test the four possible combinations of two command presentation modes (continuous, discrete) and two command types (recurring, single). We evaluated the effectiveness of this 'tactile language' according to the users' walking speed and the smoothness of their trajectory parallel to the virtual wall. Results showed that recurring continuous commands allowed users to navigate with lowest route deviation and highest walking speed. In addition, subjects preferred recurring continuous commands over other commands.
