After running the above analysis for each participant's data, we averaged the result across participants. Our data analysis suggested that the two phenomena were observed in concentric space, but the estimated range of the proprioceptive drift was slightly narrower than the range of agency. In contrast, to measure feeling of ownership and agency, 13 prefixed right hand positions were examined (Figure ​ (Figure1). As feedback can be fundamentally multisensory, the model can include multisensory parts, such as visual, tactile, and proprioceptive feedback. When participants viewed their left hands in a mirror positioned along the midsaggital axis while moving both hands, the mirror image strongly captured the left hand position and they hardly noticed the spatial offset between the hand in the mirror and the obscured real right hand (Holmes et al.

The mirror illusion: does proprioceptive drift go hand in

I build buildings inside panels and canvases,” he says and shows me the actual scaffolding he uses daily to draw his cityscapes. As a result, it is unclear whether ownership and agency could be generated when different sources of multisensory feedback are inconsistent. In self-body rehabilitation, treatments to improve motor function and pain are often carried out for patients with missing or paralyzed limbs. This exhibition is a once in a lifetime chance to experience in large scale the creativity of Daisuke Tajima, an artist capable of redefining the very potential for 2-dimensional expression.In the case of virtual reality systems, visual feedback is substituted using the virtual body depicted on a monitor. Unlike physical treatment with surgery, the treatment of ownership and agency is based upon the treatment of the patient's subjective experience. Compared to the rubber hand, the hand image in the mirror matched the real appearance of a hand almost perfectly. The axes show vertical and horizontal spatial offset between the hand in the mirror and the obscured real hand. In contrast, in the rubber hand illusion paradigm, the rubber hand does not attract participants' attention—rather, the participant must voluntarily pay attention to the rubber hand.

The plots and lines represent differences between questionnaire categories; the black square, white square, black circle, and white circle represent ownership, ownership control, agency, and agency control, respectively.

When moving one's hand in a radial direction, the elbow joint angle increases relative to that of the shoulder joint. In contrast, the aim of the current study was to describe the spatial overlap area between these phenomena in the strategic design of controlling sensations. He has traveled to many metropolises in mainland China, including Guangzhou, visited Hong Kong more than 10 times and Taiwan more than 30 times. The artist also draws inspiration from his travels to Taiwan, Hong Kong, and China, creating a unique worldview of urban spaces, redefining the potential for two-dimensional expression.

If the position of visual feedback is within the estimated area (see Figure ​ Figure3) 3) when the actual hand position is at its origin, the operator could cannot notice the spatial gap across the modalities and can maintain self-body sensation. Not all the visuo-haptic virtual reality systems and real-time controlling systems are intended for the self-body sensations tested here. Aggressive lines infused with the artist’s impulses criss-cross freely on the screen, and the accumulation of these lines creates a unique worldview.These results suggest that the offset between visual and proprioceptive feedback maintaining proprioceptive drift overlapped almost perfectly with the offset, evoking feelings of ownership and agency as a result of visual feedback from the body. Moreover, since the estimation of subjective experience relies almost solely on the qualitative method (such as the questionnaires) it is difficult to determine the reason why patients are missing ownership and agency for their limbs after treatment.
