The present invention relates generally to wearable devices, specifically those designed for wirelessly hands-free control of external systems, such as computers or presentation software, through the detection of finger movements.
In the realm of modern presentations, the effectiveness of communication is paramount. Presenters rely heavily on various tools to enhance their delivery, with one of the most common devices being the wireless presenter, also known as a clicker. This device allows the presenter to control the flow of slides, facilitating a smooth and uninterrupted presentation. However, the traditional wireless presenter, while widely used, imposes certain limitations that can impede the natural flow of a presentation. These limitations stem from the necessity of physically holding the device, which restricts the presenter's ability to use both hands freely, consequently affecting their ability to engage fully with the audience through gestures and other non-verbal communication cues.
The reliance on a handheld clicker can disrupt the fluidity of a presentation, particularly for presenters who naturally use both hands for gesturing. Effective presentation delivery often involves the use of hand gestures to emphasize points, engage the audience, and convey enthusiasm. However, when one hand is occupied with a clicker, the range of expressive gestures is significantly limited, which can reduce the overall impact of the presentation. This limitation is especially pronounced in dynamic presentations where the speaker's physical movement and hand gestures are integral to the delivery.
Moreover, the requirement to focus on operating the clicker can distract the presenter, dividing their attention between managing the device and delivering the content. This distraction can lead to a disjointed presentation, where the speaker's engagement with the audience is compromised. The cognitive load associated with operating the clicker, albeit minor, can accumulate, particularly in high-stakes presentations, leading to a decrease in the overall effectiveness of the communication. Presenters often aspire to maintain a seamless connection with their audience, and the need to constantly manage a handheld device can hinder this objective.
Another drawback of the traditional wireless presenter is its impact on the presenter's mobility. When a presenter is confined to holding a clicker, their movement across the stage may become less fluid, as they must balance the need to operate the device with the desire to move naturally. This can be particularly challenging in large venues or in presentations where the speaker needs to interact with the audience across a wide area. The physical constraint of holding a device can lead to less dynamic presentations, where the presenter is more stationary than they might otherwise be, thereby limiting their ability to fully engage the audience.
In addition to these functional limitations, traditional wireless presenters are often not adaptable to the varying needs of different users. Presenters with disabilities or those who may have difficulty using one hand for extended periods may find these devices cumbersome and challenging to use effectively. The one-size-fits-all design of many clickers does not account for the diverse needs of all presenters, which can result in a less inclusive experience. This lack of adaptability highlights a significant gap in the current market for presentation tools, where a more versatile solution could greatly enhance the usability for a broader range of presenters.
Furthermore, the evolution of presentation technology has outpaced the design of traditional clickers. As presentations become more interactive and complex, with multiple media types and the need for real-time adjustments, the limitations of a simple, handheld device become more apparent. The need for a device that can seamlessly integrate with modern presentation software, while also allowing the presenter to maintain full control without physical constraints, has become increasingly evident. The current generation of clickers fails to address these evolving needs, leading to a growing demand for a more advanced solution that can cater to the dynamic requirements of contemporary presentations.
It is within this context that the present invention is provided.

Extending from the wearable unit 100 is a pair of flexible wires 104, which serve as the connecting element between the wearable unit 100 and the sensors 106, 108 positioned on the user's hand. The flexible wire 104 is designed to be lightweight and durable, allowing for free movement of the hand and fingers without causing discomfort or interference. The wire 104 is insulated with a protective sheath to prevent damage from wear and tear during regular use, and it is routed along the side of the hand to minimize obstruction.
The sensors 106, 108 are positioned on the palm side of the hand, specifically at the base of the ring finger and middle finger, respectively. These sensors 106, 108 are configured to detect the pressure exerted by the fingers when they fold over and press against the sensors, generating signals corresponding to the pressure detected. In one implementation, the sensors 106, 108 may be pressure sensors that change resistance based on the amount of force applied, though other types of sensors, such as capacitive or optical sensors, could also be employed. The sensors 106, 108 are securely attached to the fingers using a stretchable strap 110 that wraps around the palm, holding the sensors 106, 108 in place while allowing for flexibility and comfort.
The control module within the wearable unit 100 is configured to interpret the signals received from the sensors 106, 108 via the flexible wire 104. When the user folds and presses the ring finger, the first sensor 106 detects the pressure and sends a corresponding signal to the control module, which then processes the signal and generates a control signal for transmission to the external system. Similarly, when the user folds and presses the middle finger, the second sensor 108 detects the pressure, and the control module processes this signal to generate a different control signal. These control signals are then transmitted wirelessly to the external system via the wireless communication module housed within the wearable unit 100.
The wireless communication module, integrated within the wearable unit 100, may utilize Bluetooth Low Energy (BLE) technology to establish a stable connection with the external system. The BLE module ensures that the control signals generated by the control module are transmitted efficiently, with minimal power consumption, over a typical range suitable for presentations.
Additionally, the wearable unit 100 includes a rechargeable battery, which powers the entire system. The battery is rechargeable via a USB-C port located on the wearable unit 100, allowing for convenient recharging when necessary. The control module may also include a power management system that conserves battery life by entering a low-power mode when the device is not in active use.
Upon detecting the bending motion, the first sensor 106 sends a signal through the flexible wire 104 to the control module housed within the wearable unit 100. The control module processes the signal and determines that the specific gesture corresponds to an action command, in this case, advancing to the next slide in a presentation.
The control module then generates a control signal based on this input and transmits it wirelessly via the wireless communication module integrated within the wearable unit 100. As illustrated, this wireless signal 112 is sent to an external device 114, such as a computer running presentation software. The external device 114 receives the control signal and, in response, executes the command to advance the presentation to the subsequent slide.
At the core of the wearable device is the control module, which in the present example is a microcontroller unit (MCU) 122, responsible for processing signals and executing commands. The MCU 122 is electrically connected to the power source 124, which, in this embodiment, is a rechargeable lithium-ion battery. The battery 124 provides power to all components of the wearable device and is rechargeable via a USB-C port 126 also integrated into the wearable unit.
The control module 100 is further connected to the first sensor 106 and the second sensor 108 via the flexible wire 104. The sensors 106 and 108 detect finger movements, such as bending, and send corresponding signals to the MCU 122 for processing.
The sensors may be simple pressure sensors that detect the change in resistance or the like when a user has been their corresponding finger to press them.
In other examples, the MCU 122 may run software modules that include a signal processing module and a gesture recognition module. The signal processing module filters and interprets the raw data received from the sensors 106 and 108, distinguishing between valid gestures and incidental movements. The gesture recognition module then maps the processed signals to specific commands based on predefined thresholds and patterns stored within the module.
Either way, once the device identifies a command, the MCU 122 communicates with the wireless communication module 128. In this embodiment, the wireless communication module 128 is a Bluetooth Low Energy (BLE) module that establishes a wireless connection 130 with an external device 114, here represented as a laptop. The BLE module 128 transmits the control signals generated by the MCU 122 to the laptop 114.
The laptop 114 executes the command received from the wearable device. In the current example, this command corresponds to advancing to the next slide in a presentation application running on the laptop 114. The laptop 114 may also include additional software to manage the connection with the wearable device, ensuring secure and reliable communication.
