Abstract: A method for texturing of 3D model in 2D environment includes (a) generating a texture map set for 3D model data; (b) UV unwrapping the 3D model data on each of projected planes to obtain a UV map set for each projected plane; (c) performing a 2D image authoring on the UV map set for each projected plane to produce an edited image; and (d) mapping the texture map set and the UV map set by reflecting the edited image to the texture map set and the UV map sets that are generated previously until a desired texture map set is completed.

Abstract: An apparatus for positioning and marking a location of an electromyography (EMG) electrode includes a housing having a back surface, an EMG sensor for receiving the EMG signal, an amplifying circuit for amplifying the EMG signal to generate an amplified EMG signal and an audio output terminal for outputting the amplified EMG signal as the audio EMG signal. The examinee may directly position and mark the location of the EMG electrode and may easily detect the fatigue rate of the muscle or the abnormal condition of the muscle by using the sound of the audio equipment.

Abstract: A chromatic display-type biofeedback system and method using brain waves are disclosed. After the brain waves generated from the subject, which are indicative of anxious or relaxed psychological state, are recoded by himself or herself, the subject transforms each psychological state into a chromatic bar represented by a desired color. And then, when the subject measures his or her brain waves, a specific color is displayed on a monitor, so that the subject may verify the present psychological state and repeatedly remind him or her of a color designated as a relaxed state to induce the reaching of the relaxed state. At that time, after a psychological state of the subject is verified by modeling the brain waves using a Hidden Markov Model (HMM) which is used in a statistical signal process, the results is displayed as a chromatic bar designated by the subject on a monitor, so that conversion of the relevant psychological state can be rapidly and easily achieved.
