Haptic anchoring and human postural control
(Pontificia Universidade Católica do Rio de Janeiro; Universidade de Brasília; Universidade de São Paulo, 2014-12)
Several studies have emphasized the contribution of haptic input that results from the use of rigid and non-rigid tools to the postural control system. Experimental protocols such as the light touch and the anchor system ...
A soft pneumatic actuator as a haptic wearable device for upper limb amputees: Toward a soft robotic liner
(IEEE, 2019)
Object manipulation and fluid, goal-directed, movements require sensory information for effective execution. Amputees lose this intrinsic feedback when controlling their artificial limbs and must instead rely on visual ...
Haptic Guidance for Extended Range Telepresence
A novel navigation assistance for extended range telepresence is presented. The haptic information from the target environment is augmented with guidance commands to assist the user in reaching desired goals in the arbitrarily ...
Image map based haptic rendering of surface textures on 3-D virtual objects.
(Instituto Tecnológico y de Estudios Superiores de Monterrey, 2010-12-01)
Computer haptics deals with the problem of computing the correct forces to be sent to the user through a haptic device so as to simulate a virtual object. Most haptic rendering algorithms rely only on the 3-D geometries ...
Task difficulty has no effect on haptic anchoring during tandem walking in young and older adults
(Elsevier B.V., 2018-02-14)
This study assessed the contribution of the anchor system's haptic information to balance control during walking at two levels of difficulty. Seventeen young adults and seventeen older adults performed 20 randomized trials ...
Comparison of grasping movements made by healthy subjects in a 3-dimensional immersive virtual versus physical environment
(Elsevier Science BvAmsterdamHolanda, 2011)
Haptic information provided by the anchor system reduces trunk sway acceleration in the frontal plane during tandem walking in older adults
(Elsevier B.V., 2015-11-16)
This study assessed whether the use of an anchor system benefited older adults who performed a tandem walking task. Additionally, we tested the effects of practice with the anchor system during walking on trunk stability, ...
Ergonomics and usability in sound dimension: Evaluation of a haptic and acoustic interface application for mobile devices
(2014-01-01)
This paper addresses the usability evaluation results performed in an application for mobile devices. The referred application uses haptic and audio interfaces to provide access to web content. Based on the model of listening ...
