Conclusions from previous studies with the GENTLE/A rehabilitation system[14, 15] | Design and aims of current study |
---|---|
Duration given to execute a point-to-point movement was either too short and did not allow the participant to lead the interaction or too long and led to a lazy performance of the participant. | Algorithm: An algorithm was proposed that would adapt the duration given to execute a point-to-point movement to reach an optimum value according to the performance of the participant. |
Type of the movement (reaching/returning) was influencing the performance of the participant. | Points on cube: Set of points was chosen such that different combinations of reach-return and ground level - against gravity – towards gravity movements were executed during the experiment. |
Direction of movement (away/towards) with respect to gravity was influencing the performance, as the participant’s arm was not gravity compensated. | |
Perception of depth in the Virtual Reality (VR) environment presented during the previous studies was felt difficult by the participants. | Embedded vs. Virtual: The virtual environment has been modified to improve the depth perception and an embedded set-up was also introduced to compare the performance of the participants in embedded vs. virtual environments. |
