Abstract
A human interface device including a processor coupled to a memory. A plurality of switch banks, also coupled to the processor and a rotary dial and a slider, both coupled to control circuitry, said control circuitry operable to provide positional information from the dial and the slider to the processor. The rotary dial and slider are disposed on the human interface device to form an association with the switch bank, a drive transducer coupled to said processor, said drive transducer including a plurality of LED sources spatially positioned on a positioning ring, a set of non-transitory processor instructions operable to direct the processor to provide MIDI commands through a BLE port.
Core Innovation
The invention relates to a wireless virtual display controller implemented as a human interface device that provides motion/controller sensing from a rotary dial and a slider. The controller includes switch banks with associated rotary dial and slider inputs, where positions are read by a processor and converted into MIDI compliant data.
The controller further includes a drive transducer with spatially distributed light sources on a positioning ring, and an optical-based positional tracking arrangement that identifies a position of the human interface device by a remote optical-based positional tracking system. The positional information is obtained using a receive transducer such as phototransistors/cameras, and may also use QR code/barcode scannable indicia and inertial measurement unit information.
A remote system receives the MIDI compliant data and renders a 3D/VR-aligned representation and data layers whose properties are controlled by the dial/slider inputs. The remote system operates in a client-server manner, transmitting the MIDI commands via BLE with alternatives such as DMX, and controlling virtual display UI elements such as anchored 3D GUI labels based on viewpoint or proximity.
Claims Coverage
The partial content includes three independent claims. Each independent claim contains multiple inventive features centered on receiving switch and slider position information, converting or using positional information in MIDI compliant formats, and transmitting the information to a remote system, with the positional information identified by a remote optical-based positional tracking system or generated by an inertial measurement unit.
Switch and slider position to MIDI compliant transmission
Receiving at a processor switch position information for a switch selected from a set of switches; receiving at the processor slider position information for a slider physically associated with the switch; converting the switch position and slider position into MIDI compliant data; and transmitting the MIDI compliant data to a remote system.
Tracking marker for remote optical-based positional tracking
Displaying, on a human interface device, a tracking marker operable to identify a position information of the human interface device by a remote optical-based positional tracking system.
Position identification via MIDI compliant position information
Receiving, at a processor, switch position information in a MIDI compliant format; receiving, at the processor, slider position information in a MIDI compliant format; and receiving at the processor position information from the human interface device that is operable to identify a location of the human interface device by a remote positional tracking system.
Inertial measurement unit physical position transmission
Receiving, at the processor, physical position information of the human interface device generated by an inertial measurement unit physically coupled to the human interface device; and transmitting the switch position information, slider position information, and physical position information to a remote system.
Across the independent claims, the main inventive elements are obtaining switch position information and slider position information, representing or converting positional inputs as MIDI compliant data, associating the human interface device with a tracking marker for remote optical-based positional tracking or generating physical position with an inertial measurement unit, and transmitting the resulting data to a remote system.
