The Use of a Distal-to-Tactile Sensory Substitution Interface Does Not Lead to Extension of Body Image February 7, 2012

Marek McGann presented our team’s ongoing research at the The International Conference SKILLS 2011, which was held in Montpellier, France, December 15-16, 2011.

The Use of a Distal-to-Tactile Sensory Substitution Interface Does Not Lead to Extension of Body Image

Marek McGann, Tom Froese, William Bigge, Adam Spiers, and Anil K. Seth

A range of studies in the past decade and a half indicate significant impacts of tool use on body image. In cases of intentional action, contractions of near space or experienced extensions of limbs have been shown when using tools such as rakes. It remains unclear whether the changes in body image are effected by the tool enabling perception at a distance or action/manipulation of the environment at a distance. We studied this issue using a new research tool, the Enactive Torch, a sensory substitution device specifically designed for research into perception and bodily action. The Enactive Torch allows perception at a distance without the capacity for distal action. We report a first experiment indicating that its use on a navigation task has no effect on body image.

Presentation at ASSC 15 April 5, 2011

An abstract based on our recent pilot study with the Enactive Torch has been accepted as a presentation at this year’s annual conference of the Association for the Scientific Study of Consciousness (ASSC), to be held in Kyoto, Japan, on June 9-12.

Distal perception via use of distal-to-tactile sensory substitution interface does not lead to extension of body image

Tom Froese, Marek McGann, and Anil K. Seth

It is well known that bodily transformations are entailed by practical tool-use, such as changes in body schema and body image after pointing with sticks or manipulating with rakes (see Maravita and Iriki 2004). What remains unclear is which aspects of tool-use cause the transformations. Since no effects are found in control tasks with laser pointers, the changes appear to be related to reachability (Longo and Lourenco 2006).

Talk: Enacting your body? January 18, 2011

An abstract based on the first set of psychological experiments with the Enactive Torch, which were recently conducted at MIC, University of Limerick, has been accepted as a concurrent talk at this year’s Toward a Science of Consciousness conference in Stockholm, Sweden (May 1-8, 2011).

Enacting the body? Use of distal-to-tactile sensory substitution interface does not lead to extension of body image

Tom Froese, Marek McGann, and Anil K. Seth

There is a growing amount of evidence in the cognitive sciences documenting a variety of profound personal and sub-personal transformations entailed by practical tool-use (see Maravita and Iriki 2004). In the neurosciences there is well-known evidence that tools can be incorporated into the body schema during usage. For example, distant object manipulation with rakes leads to an extension of the body schema for the arm (Iriki, et al. 1996). In psychology related effects have been observed in terms of the body image and object perception. For example, when sighted subjects had to complete tasks involving the use of elongated tools, and were subsequently blind-folded and then tapped on their arm, they consistently misjudged the position of the tactile sensations as if their arm had become extended during tool-use (Cardenali, et al. 2009).

ET3 unveiled April 6, 2009

The latest Enactive Torch prototype (ET3) was unveiled at the e-sense workshop held at the end of March. 

 

 

This version of the Enactive torch features live data streaming over Bluetooth which allows an experimenter to remotely observe and record a participant’s use of the torch. ET3 is also much more robust than the last prototype in a number of ways and many successful efforts have been made to reduce noise throughout the device. As in ET2 a number of distance / stimulation profiles are implemented in the device which can be easily selected during the experiment. The device also has lower power consumption so uses fewer batteries than the last Enactive Torch prototype (over the course of the entire workshop the torch showed no signs of running low on power).

ET3 meets all the technical goals that were originally proposed at the start of work on the Enactive Torch. Once the design of this torch has been finalised into a production-ready version, we hope to be able to start making enactive torches on demand for laboratories that wish to use the device in their research.

Workshop on Philosophy and Engineering October 23, 2008

An extended abstract on some of the philosophical aspects of using the Enactive Torch has been accepted for a talk at this year’s Workshop on Philosophy and Engineering (WPE-2008) to be held in London.

Engineering Conceptual Change: The Enactive Torch

R. Chrisley, T. Froese & A. Spiers

In the Philosophy and Engineering community, there is general agreement that interaction between the two fields can be mutually beneficial. However, there are distinctive ways in which engineering can play a crucial role in assisting the particular case of philosophy of mind, especially concerning our understanding of conscious experience and perception. The reciprocal design/use cycle of certain kinds of experience-augmenting technologies can facilitate the kind of conceptual advance that is necessary for progress toward a scientific account of consciousness, a kind of advance that is not possible to induce, it is argued, through traditional discursive, rhetorical and argumentative means. We present an example of engineering activity that plays this crucial role in informing philosophical research in the PAICS group at the University of Sussex: the design and use of a novel sensory substitution device (the Enactive Torch) as a means of inducing in the user new philosophical concepts of perceptual experience.

Interacting with the Enactive Torches September 2, 2008

The first and second prototype of the Enactive Torch were demonstrated at this weekend’s Workshop on Enactive Approaches to Social Cognition in Battle, UK. This was the first opportunity to explore the effects of participants interacting with each other via this device.

Whether it is possible to use several Enactive Torches in order to conduct a scientific study of the dynamics of perceptual crossing still requires further investigation, though it seems plausible that when two Torches cross they significantly boost each others signal.

Here are some pictures from the workshop demonstration:
