A small floating drone device for viewing on smartphones

Abstract

To provide a device that enables a user to comfortably view videos while walking without holding a smartphone in his / her hand. [Solution] The device combines a small drone with a smartphone holder, a facial recognition camera, an AI control unit, and a position control module, allowing the drone carrying the smartphone to float a specified distance in front of the user's face, allowing the user to always view the video in the optimal position.

Description

[Technical Field] This invention relates to a small drone device that holds a mobile device such as a smartphone floating in front of the user's field of vision, allowing the user to comfortably view images and information while walking or working. [Background technology] Traditionally, smartphones have been viewed by hand, which can be tiring to hold for long periods of time. Holding a smartphone while walking is also problematic from a safety perspective. Drone technology, however, is becoming increasingly compact and lightweight, and the use of smaller drones to hold devices is gaining attention. Summary of the Invention [Problem to be solved by the invention] To provide a device that allows a user to view the screen of a smartphone without using their hands even while walking. [Means for solving the problem] The device includes a smartphone holder, a small drone equipped with multiple propellers to lift the holder, and a control unit that detects the user's face and maintains a frontal position, allowing the user to comfortably view the smartphone screen while walking. [Effects of the Invention] According to this invention, users can view their smartphone screen without using their hands even while walking or working, greatly improving convenience and safety. [Brief explanation of the drawings] [Figure 1] Figure 1 is a front view of the smartphone floating drone device of the present invention. [Figure 2] FIG. 2 is a diagram showing the side structure of the retaining portion and the propeller guard. [Figure 3] Figure 3 shows an example of use, where the robot floats in front of a person. [Figure 4] Figure 4 shows the block configuration of the control unit, holding unit, camera, etc. [Figure 5] Figure 5 is a diagram to aid understanding. DETAILED DESCRIPTION OF THE INVENTION The smartphone floating drone device of this invention recognizes the user's face and autonomously positions itself at a predetermined distance in front of the user, allowing hands-free viewing of the smartphone. [Example] The following describes an embodiment of the invention with reference to the drawings. As shown in Figures 1 and 2, the device of the invention is composed of a smartphone holder 5 that holds a smartphone 1 and a small drone body 4 for levitating the smartphone 1. The drone body 4 is equipped with multiple (e.g., four) propellers 3, enabling stable levitation and positioning. The smartphone holder 5 has a clamp structure that secures the back or side of the smartphone 1 and is made of lightweight material so as not to impair the balance of the drone. Furthermore, a propeller guard 2 is provided on the outer periphery to prevent contact with the propellers, enhancing safety. As shown in Figures 3 and 4, this device detects the face of a user 6 using a camera 7 mounted on the drone body 4, and a control unit 8 analyzes the position of the face and controls it to automatically follow the face at a position 30 to 50 cm in front of the face. At this time, the device corrects its altitude and position according to the user's movements, always maintaining an angle and distance that is easy to view. In the configuration diagram shown in Figure 4, the control unit 8 includes a face recognition module that analyzes the video signal obtained by the camera 7, a position control module 9, an attitude control module, and a propeller drive unit. The face recognition module detects the user's face in real time, the position control module 9 generates movement commands to maintain the forward distance, and the attitude control module performs horizontal stability control. The propeller drive unit also controls each propeller to achieve stable hovering. Furthermore, the device of this invention is lightweight, making it suitable for indoor use, and its output can be adjusted according to the weight of the smartphone. The battery 11 is a small, highly efficient lithium polymer battery that can operate continuously for approximately 30 minutes under normal use. The camera 7 and control unit 8 are integrated, and the device is equipped with wireless communication functionality with external devices, allowing for user voice control and app integration. As described above, this device allows users to comfortably view their smartphones without occupying their hands, even while walking or working. Furthermore, face recognition control enables stable position tracking, offering high mobility and convenience compared to conventional fixed stands. Precautions for Use: When using this device, make sure there are no people or obstacles around and fly it in a safe environment. When used outdoors, it is particularly susceptible to wind and other factors, so it is best to use it in a location where stable flight can be ensured. Also, since the levitation performance varies depending on the weight and model of the smartphone, it is necessary to adjust the balance according to the instruction manual.
