Human motion and posture detection based on the multi-nodes sensors will help people to realize the law of body's movement through obtaining the kinetic parameters, so that it can be used as a quantitative analysis tool for some specific applications such as health care, sport training and military affairs, etc. Compared with optical method, inertial sensors for body motion analysis have advantages...
This paper presents an online steady-state visual evoked potential (SSVEP) based brain-computer interface (BCI). Stimuli are displayed on a liquid crystal display (LCD) screen with a frame based encoding method to elicit SSVEPs with a wide range of frequencies. This system focuses strongly on practicability and convenience, including an adequate alphabet (42 characters) that can allow a wide range...
This paper proposes an improved method for generating different phases of visual stimulus while liquid crystal display (LCD)/cathode ray tube (CRT) is employed as the visual stimulator. Since using the traditional method can only generate the limited frequencies and phases of visual stimulus, increasing the number of different flickering targets becomes very difficult in steady-state visual evoked...
