Description:FIELD OF THE INVENTION

[0001] The present invention relates to a disk jockey controller management assistive device that enhances the precision and reliability of using a disk jockey controller in both live performances and training environments. Additionally, the device disclosed in the present invention minimize user error, provide consistent control responses, and improve the overall performance experience.

BACKGROUND OF THE INVENTION

[0002] Disk jockeys often juggle multiple hardware and software components simultaneously, including mixers, turntables, effects units, and digital audio interfaces. This multitasking lead to inefficiencies, especially during live performances where timing and precision are critical. A disk jockey controller becomes essential to streamline workflow, enhance control precision, and reduce cognitive load. Without such assistance, users face challenges such as delayed transitions, misfired effects, or difficulty in maintaining audio consistency, especially in complex or fast-paced sets. Additionally, physical fatigue from constant manual adjustments and the lack of real-time feedback or automation further hinder performance quality and user comfort, necessitating an intelligent, ergonomic assistive solution.

[0003] Several DJ controller systems are currently available, such as Pioneer DJ’s DDJ series, Native Instruments’ Traktor Kontrol, and Roland DJ controllers, each offering integrated hardware-software control for mixing, effects, and sampling. However, these devices often lack adaptability to individual performance styles and do not provide intelligent assistance or automation, relying heavily on manual input. Many are also bulky, limiting portability, and have fixed control layouts that can restrict creativity. Furthermore, real-time error correction and ergonomic support features are generally absent, which can lead to user fatigue during extended sessions. These limitations highlight the need for a more adaptive, assistive device that enhances both performance quality and user comfort without compromising control precision.

[0004] US20140214189A1 discloses a wireless DJ controller includes an accelerometer, a control button, and a wireless transceiver. The wireless DJ controller detects when the control button has been depressed and accesses an output value from the accelerometer. Based on the accessed output value, the DJ controller generates a control signal and transmits the control signal to manipulate an audio signal. Methods of manipulating audio signals using the DJ controller are also disclosed.

[0005] US8362349B2 pertains to the field of control and manipulation of a digital audio signal by a user manipulable touch sensitive control surface. The present invention is specifically applicable to user manipulation of digital audio signals by disc jockeys (DJs). A touch sensitive surface substantially circumferential in shape is divided into two regions: an inner or central portion and an outer or circumferential portion. The inner portion responds to linear motion imparted by the user while the outer portion responds to circumferential motion. The linear motion imparted by the user in the central portion is used manipulate a digital audio data stream in order to impart a scratch effect.

[0006] Conventionally, many devices are available in the market for managing disk jockeys. However, the cited inventions lack adaptability and real-time error correction. These shortcomings limit performance quality, increase user fatigue, and restrict creative control. Additionally, there remains a need for an improved DJ controller that seamlessly integrates adaptive, assistive, and ergonomic features to enhance both user experience and live performance precision.

[0007] In order to overcome the aforementioned drawbacks, there exists a need in the art to develop a device that is required to be capable of adapting to individual performance styles, providing real-time error correction. Additionally, the developed device also needs to be ergonomic, reduce user fatigue, enhance creative control, and improve overall workflow efficiency, thereby elevating live performance quality and user comfort for disk jockeys.

DETAILED DESCRIPTION OF THE INVENTION

[0018] The following description includes the preferred best mode of one embodiment of the present invention. It will be clear from this description of the invention that the invention is not limited to these illustrated embodiments but that the invention also includes a variety of modifications and embodiments thereto. Therefore, the present description should be seen as illustrative and not limiting.

[0019] In any embodiment described herein, the open-ended terms "comprising," "comprises,” and the like (which are synonymous with "including," "having” and "characterized by") may be replaced by the respective partially closed phrases "consisting essentially of," consists essentially of," and the like or the respective closed phrases "consisting of," "consists of, the like.

[0020] As used herein, the singular forms “a,” “an,” and “the” designate both the singular and the plural, unless expressly stated to designate the singular only.

[0021] The present invention relates to a disk jockey controller management assistive device that supports both learning and professional applications by automatically modifying its operational behavior based on the mode selected by the user. In addition, the device ensures an optimized interface and performance level, providing beginners with guided assistance while offering advanced control features suited to experienced disk jockeys during live or studio sessions.

[0022] Referring to Figure 1, an isometric view of a disk jockey controller management assistive device is illustrated, comprising a body 101 equipped with a plurality of actuators 102, a gripping assembly 103 installed on the body 101 via a primary sliding arrangement 104, a securing means 105 mounted on the body 101 via a rotating assembly 106, attached to an extendable L-shaped link 107 connected to a secondary sliding arrangement 108, a crowd inspection unit 109 installed on the body 101, a microphone 110 installed on the body 101 and a holographic projection unit 111 arranged on the body 101.

[0023] The device disclosed in the present invention comprises of a plurality of actuators 102, which are responsible to securely hold an auxiliary disk jockey controller for providing stability to the disk jockey during operation. The actuators 102 ensure the disk jockey controller remains firmly in place, preventing movement or slipping, which enhances overall performance and safety.

[0024] To activate the device, the user manually presses a push button which is installed on the body 101. Upon pressing the button, the circuits within the device gets close, allowing electric current to flow. The push button has an outer casing and an inner arrangement, including a spring and metal contacts. When the button is pressed, the spring-loaded assembly inside is pushes down on. In the default state, the internal contacts are apart, so the circuit is open and no electricity flows. Pressing the button makes the contacts touch each other, closing the circuit and allowing electricity to flow, which activates an inbuilt control unit that regulates the further options of the device.

[0025] Upon activation of the device, the control unit activates an inbuilt communication module for establishing a wireless connection between the control unit and a computing unit that is inbuilt with a user-interface and accessed by the user for enabling the user to create personalized profiles and select between a learner mode or professional mode. The user interacts with the interface through a touch screen, keyboard, or other input methods available on the computing unit. The computing unit mentioned herein includes, but not limited to smartphone, laptop, tablet.

[0026] The communication module mentioned herein includes, but not limited to Wi-Fi (Wireless Fidelity) module, Bluetooth module, GSM (Global System for Mobile Communication) module. The communication module used in the device is preferably the Wi-Fi module. The Wi-Fi module enables wireless communication by transmitting and receiving data over radio frequencies using IEEE 802.11 protocols. It connects to a network via an access point, converting digital data into radio signals. The module processes TCP/IP protocols for data exchange, interfaces with microcontrollers through UART/SPI, and ensures encrypted communication using WPA/WPA2 security standards for secure and efficient wireless connectivity. On the basis of the profile of the user, the control unit dynamically modifies component functioning to enable customized instruction for novice users and guarantee smooth audio track playback with ideal rest periods for expert users.

[0027] Post creating the profile of the user, the controller unit actuates a primary sliding arrangement 104 installed on the body 101 to provide horizontal movement to a gripping assembly 103 arranged over the primary sliding arrangement 104 over switches and jog wheels of the controller. The primary sliding arrangement 104 includes a dovetail sliding unit for providing horizontal movement to the gripping assembly 103.

[0028] The dovetail sliding unit provides horizontal movement to the gripping assembly 103. The dovetail sliding unit consists of a fixed base with a dovetail guide, and a moving slide (carriage) that fits tightly into the guide. The slide is connected to the gripping assembly 103 and moves along the guide, ensuring smooth linear motion without lateral play. Gib strips are used to maintain a snug fit and adjust for wear. Motion is provided via a lead screw using a motor. The motor is actuated to drive the slide for moving the gripper horizontally in order to position the gripping assembly 103 over the switches of the controller.

[0029] The gripping assembly 103 includes a motorized clamp controlled by an extendable L-shaped rod, connected to the primary sliding arrangement 104, which are configured to actuate at pre-determined time-intervals for selective manipulation of the controller’s switches. The extendable rod is actuated by the control unit for positioning the motorized clamp in proximity of the switches of the controller.

[0030] The extendable rod is powered by a pneumatic arrangement that includes an air compressor, air cylinder, air valves and piston which works in collaboration to aid in extension and retraction of the rod. The pneumatic arrangement is operated by the microcontroller, such that the microcontroller actuates valve to allow passage of compressed air from the compressor within the cylinder from one end, the compressed air further develops pressure against the piston and results in pushing and extending the piston. The piston is connected with the rod and due to applied pressure the rod extends and similarly, the microcontroller retracts the rod by pushing compressed air via the other end of the cylinder, by opening the corresponding valve resulting in retraction of the piston, and the retraction of the rod. Thus, the microcontroller regulates the extension/retraction of the rod to position the clamp in proximity of the switches of the controller.

[0031] The clamp is then actuated by the control unit for manipulation of controller switches to maintain ideal audio track parameters during operation. The motorized clamp works by using an electric motor connected to a sliding jaw via a screw. The motor provides power to the screw that is attached to the fixed frame of the clamp. As the screw rotates, it pushes or pulls the sliding jaw towards or away from the fixed jaw depending on the direction of rotation. This movement allows the clamp to manipulate the switches.

[0032] In synchronization with the gripping assembly 103, the controller unit actuates a rotating assembly 106 installed on the body 101 to engage and rotate jog wheels, for optimizing scratching, beat-matching and track navigation in real-time. The rotating assembly 106 including a ball detent assembly 107, attached to an extendable L-shaped link 107 connected to a secondary sliding arrangement 108, for providing controlled movement to a securing means 105 configured with the rotating assembly 106 for precise jog wheel manipulation to enhance audio track performance.

[0033] The secondary sliding unit works in the similar manner as mentioned above. The ball detent assembly 107 works by using a spring-loaded ball to temporarily lock or position a mechanical component. The spring applies constant pressure, pushing the ball outward from a housing. When the ball aligns with a groove or recess in a mating part, it snaps into place, holding the component securely. When force is applied, the ball is pushed back into the housing, compressing the spring and allowing movement. Once the force is removed and alignment is restored, the spring pushes the ball back into the groove.

[0034] A microphone 110 installed on the body 101 for capturing voice signals. When the user speaks to give voice commands, the given commands are first captures by the microphone 110. These sound waves from the captured voice commands hit the diaphragm which vibrates back and forth in response to sound waves. The back and forth movement of the diaphragm is then transferred to a capacitor connected to the microphone 110 that converts the vibrations into an electrical signal that mirrors the pattern of the sound waves. The electrical signal is sent to the microcontroller for further processing.

[0035] In accordance to the input commands through the microphone 110, a crowd inspection unit 109 installed on the body 101 is activated by the control unit for detecting physiological behavior of an audience to inform audio track selection. The crowd inspection unit 109 includes a vertical cascading slider and a Laser Doppler Vibrometer (LDV) that is configured to measure an average heart rate of the audience, enabling the control unit to retrieve suitable audio tracks from a linked database, which corresponds to the detected physiological responses of the crowd.

[0036] The vertical cascading slider is actuated by the microcontroller for position the crowd inspection unit 109 at the required height. The vertical cascading slider is a telescopic arrangement integrated into the crowd inspection unit 109 to adjust its length dynamically. The telescopic arrangement is powered by a pneumatic unit that embodies an air compressor, air cylinder, air valves, and piston which work in collaboration to perform the extension and retraction of the motorized sleeve. The pneumatic unit comprises a nested tube arrangement that contains multiple hollow tubes connected concentrically, connected to the air cylinder that provides compressed air to the telescopic arrangement to move the attached ... Controlled by the microcontroller, the cascading slider extends or retracts in segments for allowing the crowd inspection unit 109 to adapt its length based on the requirements.

[0037] The crowd inspection unit 109 detects audience physiological responses to guide audio track selection in real time. The crowd inspection unit 109 uses sensors such as a Laser Doppler Vibrometer (LDV) that is configured to measure an average heart rate of the audience.

[0038] The Laser Doppler Vibrometer detects heartbeat of the audience by measuring tiny vibrations on the body 101 surface caused by cardiac activity. The vibrometer emits a laser beam onto areas like the chest or neck, where each heartbeat produces subtle surface motion. The reflected laser light experiences a phase or frequency shift due to these vibrations. The vibrometer analyzes these changes using interferometry or the Doppler effect to determine vibration amplitude and frequency. These measurements are then processed to extract the heartbeat signal, enabling the control unit to retrieve suitable audio tracks from a linked database, which corresponds to the detected physiological responses of the crowd.

[0039] The suitable audio track retrieved by the crowd inspection unit 109, a holographic projection unit 111 arranged on the body 101 is actuated by the control unit for projecting assistive three-dimensional visuals for training and supporting professional operations. The holographic projection unit 111 projects the 3D visual by converting digital map data generated by control unit into an interference pattern using coherent light. The interference pattern is then projected onto a surface and the light diffracted by the interference pattern reconstructs the 3D image of the visuals. The resulting holographic image appears to be displayed on the surface, giving a three-dimensional view of the map.

[0040] Moreover, a battery is associated with the device to supply power to electrically powered components which are employed herein. The battery is comprised of a pair of electrodes known as a cathode and an anode. A voltage is generated between the anode and cathode via oxidation/reduction and thus produces the electrical energy to provide to the device.

[0041] The present invention works best in the following manner, where the plurality of actuators 102 as disclosed in the invention securely holds the auxiliary disk jockey controller, activated by the user via the push button that closes internal circuits to allow electric current flow, triggering the control unit. Upon activation, the control unit initiates the communication module, preferably the Wi-Fi module, to establish wireless connectivity with the computing unit for profile creation and mode selection. Based on the user profile, the control unit dynamically controls the primary sliding arrangement 104, consisting of the dovetail sliding unit, for horizontal movement of the gripping assembly 103 equipped with the motorized clamp actuated through the extendable L-shaped rod powered by the pneumatic arrangement comprising the air compressor, air cylinder, air valves, and piston. This enables selective manipulation of controller switches. In synchronization, the control unit engages the rotating assembly 106 featuring the ball detent assembly 107, extendable L-shaped link 107, and secondary sliding arrangement 108 for real-time jog wheel manipulation. Voice commands are captured by the microphone 110 and processed to control functions. The crowd inspection unit 109, mounted on the vertical cascading slider with the telescopic pneumatic arrangement, detects audience physiological responses using the Laser Doppler Vibrometer to inform real-time audio track selection. The control unit actuates the holographic projection unit 111 for projecting three-dimensional visuals to support training and professional operations.
