駆動装置、触覚提示装置及び駆動方法
Abstract:
【課題】リアルな触感の提示が可能な空間振動発生装置の駆動装置、触覚提示装置及び駆動方法を提供すること。 【解決手段】本技術に係る駆動装置は、周波数が1Hz以上100Hz未満である第1低周波を第1変調波とし、周波数が100Hz以上300Hz以下である第2低周波を上記第1変調波によって振幅変調してなる波形を第2変調波とし、周波数が20kHz以上100kHz以下である高周波を上記第2変調波によって変調してなる波形を有する駆動信号を生成し、上記駆動信号を圧電素子に出力する。 【選択図】図1
Abstract(English):

To provide a driving device of a space vibration generator that can present a real sense of feeling, a tactile sense presenting device, and a method for driving.SOLUTION: The driving device according to the present technique generates a driving signal which has a first low frequency, which is at least 1 Hz and lower than 100 Hz, as a first modulation wave, has a wave obtained by amplitude-modulating a second low frequency, which is at least 100 Hz and 300 Hz at a maximum, by the first modulation wave as a second modulation wave, and has a wave obtained by modulating a high frequency, which is at least 20 kHz and 100 kHz at a maximum, by the second modulation wave. After that, the driving device outputs the driving signal to a piezoelectric element.SELECTED DRAWING: Figure 1
