Sensation and Perception-Virtual Object Weight during Manipulation

Sensation and Perception-Virtual Object Weight during Manipulation

Article 1

In the article “Effect of Cutaneous Feedback on the Perception of Virtual Object Weight during Manipulation,” Park et al. (2020) delve into the extent to which lateral tactile feedback and kinesthetic feedback influence how the weight of virtual objects is perceived during manipulation. Virtual reality technologies employ various haptic technologies to allow users to interact and manipulate virtual objects by creating various tactile sensations. The tests explored cutaneous feedback to kinesthetic feedback. Fingertips help perceive an object’s weight. Therefore, the use of tactile feedback to kinesthetic feedback can affect how users perceive the weight of virtual objects. The authors assume that tactile information can optimally be integrated with kinesthetic feedback to create a better perception of the virtual object’s weight during the manipulation of virtual objects. During the study, the participants’ avatar fingers were used to feel the virtual fingers. The findings show that combining lateral cutaneous feedback with kinesthetic feedback can significantly improve the perception of the weight of virtual objects.

I learned about cutaneous mechanoreceptors and how they influence sensation and perception in class settings. The use of both lateral cutaneous feedback and kinesthetic to improve the perception of weight for virtual objects is quite relatable to applying both types of sensations in real-life settings. From my study lessons, cutaneous feedback is related to the information based on how the sensors on the skin create the perception of an actual object based on the distribution of pressure on the skin. The concepts of cutaneous perception application in the virtual world discussed in this paper are applicable to health and can provide a solution to conditions such as balance, vision, and hearing impairments (Nyasulu et al., 2021).

Article 2

Vu et al. (2022), in the article “Restoration of Proprioceptive and Cutaneous Sensation Using Regenerative Peripheral Nerve Interfaces in Humans with Upper Limb Amputations,” investigate if the activation of regenerating peripheral nerve interfaces using electrical stimulation can yield detectable proprioceptive and/or tactile sensations in upper limb amputations. This investigation aims to determine if electrical stimulation of tactile sensations through the mitigation of neuroma formation can treat and prevent pain following an amputation. The functionality of prosthetic limbs, just as normal body limbs, depends on meaningful sensations relatable to previous experiences. The application of regenerative peripheral nerve interfaces acts as a two-way motor and sensory neuro-prosthetic interface that can improve prosthetics functionality. The authors found that stimulating the regenerative peripheral nerve interfaces on patients with good and prosthetic arms using a real and a phantom arm in which the participants reported experiencing proprioceptive sensations in the phantom hand. Further, stimulation of specific nerves, such as the median and ulnar, created sensory flexions on specific parts of the arm, such as on specific fingers.

The concepts discussed in this paper, especially the stimulated regenerative peripheral nerve interfaces to improve the embodiment of prosthetics and reduction of pain postamputation, apply the same strategies I have explored within the classroom setting, including mirror therapy and motor imagery. Both mirror therapy and motor imagery effectively transfer cutaneous sensations from the good arm to the prosthetic arm, which has a significant impact on the ownership and feeling of the location of the prosthetic arm. Overall, the paper presents empirical evidence on how and why the application of peripheral nerve interfaces to restore proprioceptive and cutaneous sensation can improve the prosthetic embodiment and quality of life for people with amputated upper limbs.
