Real time control of the ASBGo walker through a physical human–robot interface
Martins, Maria M.; Santos, Cristina; Frizera, Anselmo; Ceres, RamónAvailable online 5 November 2013 ; In this work it is presented the development of the conceptual design, implementation and validation of a Smart walker with an inexpensive integrated interface. This interface is based on a joystick and it intends to extract the user’s command intentions. Preliminary sets of experiments were performed which showed the sensibility of the joystick to extract navigation commands...
Multivariate analysis of walker-assisted ambulation
Martins, Maria M.; Santos, Cristina; Costa, L.; Frizera Neto, AnselmoIn an aging society it is extremely important to develop devices which can support and aid the elderly in their daily life. Walkers play an important role, due to the large number of potential users, its simplicity and their ambulatory potential. However, there are no clinical evidences that prove the efficacy of such devices, mainly rollators that present forearm supports. In this context, the authors aim to p...
A novel human-machine interface for guiding : the NeoASAS Smart Walker
Martins, Maria M.; Frizera Neto, Anselmo; Urendes, Eloy; Santos, Cristina; Ceres, R.In an aging society it is extremely important to develop devices, which can support and aid the elderly in their daily life. This demands tools that extend independent living and promote improved health. In this work it is proposed a new interface approach integrated into a walker. This interface is based on a joystick and it is intended to extract the user’s movement intentions. The interface is designed to be...
Assistive mobility devices focusing on smart walkers : classification and review
Martins, Maria M.; Santos, Cristina; Frizera Neto, Anselmo; Ceres, R.In an aging society it is extremely important to develop devices, which can support and aid the elderly in their daily life. This demands means and tools that extend independent living and promote improved health. Thus, the goal of this article is to review the state of the art in the robotic technology for mobility assistive devices for people with mobility disabilities. The important role that robotics can pl...
Revisão e classificação de dispositivos de treino e reabilitação da marcha humana
Martins, Maria M.; Frizera Neto, Anselmo; Santos, Cristina; Ceres, R.O treino de marcha convencional recorre a uma passadeira. Este tipo de treino comporta custos consideráveis, para além de exigir o constante envolvimento e esforço de dois ou três terapeutas. De modo a reduzir este esforço, inúmeros grupos de investigação têm desenvolvido uma série de alternativas a este método através da ajuda de dispositivos robóticos que realizam a assistência de pacientes na passadeira. Par...
Review and classification of human gait training and rehabilitation devices
Martins, Maria M.; Frizera Neto, Anselmo; Santos, Cristina; Ceres, R.The number of people with reduced mobility capabilities increases every year. This reduction arises mainly due to spinal cord injuries; strokes which caused hemiparesis; or due to an advanced age. This decrease in mobility is a factor that influences both their quality of life and their dependence of others in daily life. Thus, it becomes necessary to find means and tools to prevent, compensate, improve or help...
Small bowel tumors detection in capsule endoscopy by gaussian modeling of color...
Martins, Maria M.; Barbosa, Daniel; Ramos, Jaime; Lima, C. S.This paper is concerned with the classification of tumoral tissue in the small bowel by using capsule endoscopic images. The followed approach is based on texture classification. Texture descriptors are derived from selected scales of the Discrete Curvelet Transform (DCT). The goal is to take advantage of the high directional sensitivity of the DCT (16 directions) when compared with the Discrete Wavelet Transfo...
