“…In these studies, the subjects used the new auditive information to reorganize and adapt the existing internal model, improving the overall performances of their limbs (Ghez et al, 2000;Dursun et al, 1992;Huang et al, 2006Huang et al, , 2005Dozza et al, 2004;Moran et al, 1995;Kousidou et al, 2007).

Figure 1 shows a diagram describing the feedback methods used for different applications (Ghez et al, 2000;Dursun et al, 1992;Huang et al, 2006Huang et al, , 2005Dozza et al, 2004;Moran et al, 1995;Kousidou et al, 2007;Jovanov et al, 1999;Karron and Bucholz, n.d.;Wang and Shamma, 1995;Hernández et al, 2005;Dillon et al, 2004;Szeto and Saunders, 1982). It can be noticed that auditive feedback has been used only to help users improve the dynamics of their own limbs, but not to convey information of an external limb's dynamics.…”

It is widely agreed that amputees have to rely on visual input to monitor and control the position of the prosthesis while reaching and grasping because of the lack of proprioceptive feedback. Therefore, visual information has been a prerequisite for prosthetic hand biofeedback studies. This is why, the underlying characteristics of other artificial feedback methods used to this day, such as auditive, electro-tactile, or vibro-tactile feedback, has not been clearly explored. The purpose of this paper is to explore whether it is possible to use audio feedback alone to convey more than one independent variable (multichannel) simultaneously, without relying on the vision, to improve the learning of a new perceptions, in this case, to learn and understand the artificial proprioception of a prosthetic hand while reaching. Experiments are conducted to determine whether the audio signals could be used as a multi-variable dynamical sensory substitution in reaching movements without relying on the visual input. Two different groups are tested, the first one uses only audio information and the second one uses only visual information to convey computer-simulated trajectories of two fingers.

“…The auditive systems, as the visual system, is capable of sensing and processing large amounts of information in real time, which makes it a good biofeedback channel option to convey dynamical data from the artificial limb to the person for training purposes [10][11][12][13][14][15][16][17][18][19]. Audio tones or music have been used as proprioceptive feedback for neuromotor rehabilitation therapies in order to guide a person achieving certain tasks, like reaching and grasping [10][11][12][13][14][15][16] more accurately with good outcome.…”

Visual input is one of the prerequisites for most biofeedback studies for prosthetic hand control, since amputees lost part of their proprioception. This study explores whether it is possible to use audio feedback alone to convey more than one independent variable, without relying on visual input, to improve the learning of new perceptions; in this case artificial proprioception of a prosthetic hand. This way different features of the audio feedback can be observed to design applications capable of coupling different sensory inputs that will improve the acceptance and control of prosthetic devices. Experiments were conducted to determine whether the audio signals can be used as a multi-variable dynamical sensory substitution in reaching movements. The results showed that it is possible to use auditive feedback to create a body image without using the visual contact as a guide, thus to assist prosthetic hand users by internalizing new perceptions..

Visual information is one of the prerequisites for most biofeedback studies. The aim of this study is to explore how the usage of an audio aided training helps in the learning process of dynamical electro-tactile perception without any visual feedback. In this research, the electrical simulation patterns associated with the experimenter's finger postures and motions were presented to the subjects. Along with the electrical stimulation patterns 2 different types of information, verbal and audio information on finger postures and motions, were presented to the verbal training subject group (group 1) and audio training subject group (group 2), respectively. The results showed an improvement in the ability to distinguish and memorize electrical stimulation patterns correspondent to finger postures and motions without visual feedback, and with audio tones aid, the learning was faster and the perception became more precise after training. Thus, this study clarified that, as a substitution to visual presentation, auditory information could help effectively in the formation of electro-tactile perception. Further research effort needed to make clear the difference between the visual guided and audio aided training in terms of information compilation, post-training effect and robustness of the perception.
