Techniques for intraoral data manipulation are disclosed. Wired connectivity between a first device inside a mouth and a second device inside the mouth is provided. The wired connectivity is provided by a dual-frequency serpentine coupling. The dual-frequency serpentine coupling enables three-dimensional flexibility for the coupling inside the mouth. Wireless connectivity is provided between the first device and a device outside the mouth. The wireless connectivity is enabled using a wireless transceiver. Data transmission is enabled between the first device and the device outside the mouth. The dual-frequency serpentine coupling includes a higher-frequency serpentine shape overlaid on a lower-frequency serpentine shape. The higher-frequency serpentine shape can be overlaid on a continuous segment of the lower-frequency serpentine shape. The higher-frequency serpentine shape can be overlaid on one or more discontinuous segments of the lower-frequency serpentine shape. The discontinuous segments are folded adjacent to each other.

A three-dimensional control system includes an input device, a computing device, and a tracking assembly. The input device can include an input sensor, an inertial measurement unit sensor, and an ultrasonic speaker. The tracking assembly can include a plurality of ultrasonic microphones and an inertial measurement unit disposed on or with the computing device. The plurality of ultrasonic microphones can include three microphones in a first plane and at least one other ultrasonic microphone disposed out of the first plane. The ultrasonic microphones can be configured to detect ultrasonic waves output by the speaker of the input device and the computing device can triangulate the position of the input device relative to the computing device in space.
