Kinesthetics is the perception of one’s own body motion. Some examples may better explain kinesthetic sensitivity. Few young people have any difficulty in recognizing when they are sitting upright or are partially prone. Nor do they often make mistakes when called upon to locate their feet relative to their knees, such as when climbing on uneven terrain. Usually they are able to make generalized postural adjustments when getting to their feet and compensate for slight misalignments without giving the matter any thought. Some older adults, on the other hand, are not able to control body position or movement unconsciously; the loss of their kinesthetic senses leaves them vulnerable to accidental falls and postural instability. For each of us the sense of movement, touch, and position depends in part on receptors located in muscles, joints, and the skin. For various reasons, some of which can be traced to sensory impairments and some to a breakdown of the brain’s integrative capacities, the dizziness or vertigo reported by some older adults is attributed to dysfunctions in these receptors as well as to the integration of visual cues with the receptor information.
Spatialized Vibrotactile Feedback Improves Goal-Directed Movements in Cluttered Virtual Environments

Haptic perception combines two types of perceptual information. The kinesthetic perception delivers information on both the relative positions and movements of body parts and muscular effort. Tactile perception enables the feeling of different types of stimulus on the skin, such as thermal properties, vibration, pressure, and pain. Touch has been used to substitute other perceptions (visual, auditory) or as an extra information medium. Three main transducer types are used for tactile display of spatial patterns on the skin: static tactile, electrotactile, and vibrotactile (Kaczmarek & Bach-y-Rita, 1995).
Examination of effectiveness of kinaesthetic haptic feedback for motor imagery-based brain-computer interface training

In this study, we explored a method for users to experience kinesthetic haptic feedback that passively moved their arm according to detected movement intention. This will be valuable in next steps of our study where users will feel the feedback about their motor imagery and be able to operate a robot without needing visual feedback.
