Somatosensation01:33

Somatosensation

42.0K
The somatosensory system relays sensory information from the skin, mucous membranes, limbs, and joints. Somatosensation is more familiarly known as the sense of touch. A typical somatosensory pathway includes three types of long neurons: primary, secondary, and tertiary. Primary neurons have cell bodies located near the spinal cord in groups of neurons called dorsal root ganglia. The sensory neurons of ganglia innervate designated areas of skin called dermatomes.

Sensory Perception: Organization of the Somatosensory System

10.3K
The somatosensory system is the central and peripheral nervous system component that senses and processes touch, pressure, pain, temperature, and body position or proprioception. The process of sensation takes place at three levels:
The receptor level:
The receptor level is the first stage of sensation. It involves the detection of a stimulus by specialized sensory receptors. The stimulus must arrive within the receptor's receptive field. Next, the receptor converts the energy of the...

Design Example: Resistive Touchscreen

570
A device engineer plays a crucial role in designing user interfaces for mobile devices. One such interface is the resistive touchscreen, which fundamentally consists of two metallic layers: a flexible upper layer and a rigid lower layer, separated by a narrow gap. The high resistance between these two layers is a key characteristic of this design.
When a user touches the screen, the two layers make contact at a specific point known as the touchpoint. This contact reduces the resistance between...

Sensory Functions of the Skin01:16

Sensory Functions of the Skin

7.1K
The skin is the largest organ of the human body and plays a crucial role in our sensory perception. It contains a vast network of sensory receptors that contribute to the skin's protective function by perceiving physical, biological, and environmental cues and generating relevant responses.
There are two main categories of receptors on the skin: capsulated and non-capsulated. The non-capsulated ones are mainly the pain receptors. The capsulated ones can be further categorized based on the...

The Sense of Self: Reflected Self-Appraisal and Social Comparison

54.3K
According to Charles Cooley, we base our image on what we think other people see (Cooley 1902). We imagine how we must appear to others, then react to this speculation. We don certain clothes, prepare our hair in a particular manner, wear makeup, use cologne, and the like—all with the notion that our presentation of ourselves is going to affect how others perceive us. We expect a certain reaction, and, if lucky, we get the one we desire and feel good about it. But more than that, Cooley...

Tactile and Chemical Senses01:27

Tactile and Chemical Senses

481
Tactile senses encompass touch, temperature, and pain, each mediated by specific receptors. Touch receptors detect mechanical energy or pressure against the skin. Sensory fibers from these receptors enter the spinal cord and relay information to the brain stem. Here, most fibers cross over to the opposite side of the brain. The touch information then moves to the thalamus, which projects a map of the body's surface onto the somatosensory areas of the parietal lobes in the cerebral cortex.

Area of Science:

  • Human-Computer Interaction
  • Neuroscience
  • E-textile Design

Background:

  • Rapid technological advancements are shifting our perception of reality.
  • While e-textiles are used in applications like exergame and space suits, their potential for creating embodied experiences through internal garment sensations is underexplored.

Purpose of the Study:

  • To investigate the transformative potential of internal garment sensations for altering body perception.
  • To explore the use of vibrotactile array-based fabrics and haptic metaphors in art-science collaboration.

Main Methods:

  • An iterative design process combining neuroscience findings and body-centered design principles.
  • Two user studies were conducted to evaluate the effects of various vibration patterns on body perception and emotional responses.
  • Utilized 2D vibrotactile array-based fabrics to create spatial haptic metaphors.

Main Results:

  • Vibration patterns within textiles can be designed to evoke specific body perceptions, such as feeling heavy or strong, by drawing parallels to material sensations like rocks.
  • User studies demonstrated the potential of these haptic metaphors to influence body perceptions and emotional responses.

Conclusions:

  • The research introduces a novel approach to sensorial design for embodied experiences based on "material perception" and haptic metaphors.
  • Haptic clothing presents significant opportunities for altering body perception and enhancing embodiment in virtual environments and human-computer interaction.
