Recently, steady-state visual evoked potential (SSVEP)-based brain-machine interface (BMI) speller systems have shown a great performance increase with high information transfer rate (ITR) and short response time. In previous BMI speller systems, however, users should utilize the systems at fixed viewing distance environment for evoking SSVEP signals because a variation of the SSVEP signals according...
In the Brain-Computer Interface (BCI) based on Steady-State Visual Evoked Potential (SSVEP), the viewing distance is usually fixed in the 1 m. However, the performance of SSVEP was decreased when the viewing distance is increasing. This paper aims to investigate the effects of viewing distance variation to the SSVEP. We designed an experimental environment with different viewing distance and generated...
Goal: Micromagnetic stimulation using coils sufficiently small to be implanted has been suggested as a potential method to overcome the limitations of electrical stimulation. We investigated the temperature increases in the brain implanted with planar coils. Methods: We conducted computational simulations on the thermal effects of implantable magnetic stimulation in a brain model using finite-element...
This paper examines and summarizes the research trends in the field of rehabilitation robotics for treadmills that automatically adapt to the walker's desired speed. Treadmill training is a method of ambulatory rehabilitation for patients who have lost their ambulatory function before or after a joint replacement surgery, or from arthritis, a stroke, or a spinal cord injury. The existing treadmill...
Gait training equipment, which enables the handicapped and elderly to perform activities independently, primarily includes a rehabilitation exercise robot that assists a person's movement by detecting limb motions and a robot that moves the arms and hands by using a person's neuronal signals. Gait training equipment is part of the category of medical robots, and specific standardized documents are...
This paper aims to investigate the effects of steady-state visual evoked potential (SSVEP) in the aspects of viewing distance variation for a smart TV control system. We designed an experimental environments with different viewing distance. Four healthy people (age 27.5±1, male) participated in the experiment. Four visual stimuli with a round shape were designed and presented on LED monitor flickering...
