  • Publication number: 20230409155
    Abstract: Operation input device with few gesture operation erroneous detections is provided. Operation input device includes substrate; plurality of detecting electrodes provided on substrate surface; detecting unit detecting capacitance occurring between each detecting electrode and operating body upon operating body being brought close to substrate; and determining unit determining whether gesture operation by operating body has been performed.
