Mobile Device Gesture Control for DJ Audio Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Disc jockeys face challenges in controlling audiovisual equipment while interacting with the audience, as they must remain stationary near the DJ console to manage the equipment effectively, leading to audience disengagement and reduced performance quality.
Innovation Solution
A computer-implemented method using a mobile device to determine the angle of interest and select output devices, allowing for gesture-based control of audiovisual equipment, enabling DJs to move freely and dynamically adjust performance settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the DJ remains at the DJ console to control equipment, then equipment control capability is improved, but audience monitoring capability deteriorates
Solution Approach 1:
The system divides control functionality between a fixed DJ console for equipment control and a mobile computing device for audience monitoring. The DJ can physically separate these functions by using the mobile device to control equipment while moving around to monitor the audience, thus segmenting the single operator into two functional roles.
Solution Approach 2:
The mobile computing device acts as an intermediary between the DJ and the audio equipment. Instead of directly controlling equipment from a fixed position, the DJ uses the mobile device as a mediator that can be moved freely while maintaining wireless connectivity to control audio output devices.
2Loss of information
If the DJ moves freely to interact with the audience, then audience engagement is improved, but equipment control capability deteriorates
Solution Approach 1:
The system replaces the mechanical connection between the DJ and equipment (physical presence at the console) with wireless electronic control. The mobile computing device enables the DJ to control audio equipment remotely through wireless communication, substituting physical proximity with electronic signal transmission.
Solution Approach 2:
The control system transitions from a static configuration (DJ fixed at console) to a dynamic one where the DJ can move freely while maintaining control capability. The mobile computing device enables dynamic positioning while preserving equipment control through wireless connectivity and spatial audio processing.
3Loss of information
If a sound engineer operates the DJ console, then the DJ can interact with the audience, but dynamic performance tuning capability deteriorates
Solution Approach 1:
The DJ maintains self-service capability for equipment control by using the mobile computing device. Instead of delegating control to a sound engineer, the DJ independently controls audio equipment while interacting with the audience, ensuring real-time adaptive performance tuning remains with the performer.
Data Source
AI summary
In various embodiments, a control application enables mobile control of output devices, such as speakers. In operation, the control application receives visual data from a mobile device and one or more cameras that track motions associated with the mobile device. Based on the location of the mobile device and an angle of interest indicated by the visual data transmitted from the mobile device, the control application selects one or more output devices. The control application then processes the visual data provided by the cameras in order to identify and extract gestures and transmit associated control signals to the selected output devices.
