Learning materials for the visually impaired.

Abstract

This invention is a learning tool for the visually impaired, consisting of: The three main components are: 1. Internal structure, 2. Control device, and 3. Cover. The internal structure includes the base. The main structure is a circular plate with a stand. It has a steel frame that can rotate around the base of the main structure, which houses the media base. Learning dance moves or choreography using three-dimensional models and embossed pin art displayed in multiple locations. The lesson consists of one media base, representing one dance move or sequence, controlled by a microcontroller. Controlling two motors, one motor drives the media base to rotate left and right for selecting lessons, and the other controls the base's movement. A motor-driven mechanism lifts the media base above the perforated cover on top, raising the base one lesson at a time. There is a sound from... The audiobook instructs learners to touch three-dimensional models and embossed pin art while the content is narrated. The dance lesson shows the steps and instructs the user to follow the lesson displayed on the front. There are three buttons: a button to play. The button on the right switches to the next lesson, and the button on the left switches to the next lesson.

Claims

OCR 09WP 01 / 09 / 2568 1. Learning materials for the visually impaired, which consist of three main components: the internal structure. The control device / cover has the following specific characteristics: The internal structure consists of: - The main structural base (1) is a circular plate with raised edges to support the cover (2) nearby. On the outer edge there is a lock (3) which is an angle iron installed to lock the media base (4) in place. At the center of the circular plate, there is a central axis (5) which acts as the axis of rotation of the steel frame (6) base. The main structure (1) has an inner base (15) which supports the media stand (16), on which the media stand (16) is mounted. Connected to the slide rail assembly (17) for up and down movement along the driven axis of the piston motor. (Linear Actuator) (18) Casters (31) are installed on the table legs for easy movement. - The steel frame (6) is assembled onto the main structural base (1) by placing it on top of the main structural base (1). The central circular opening (7) is fitted onto the central axis (5) to allow rotational movement on the main structural base (1). The central axis (5) has the form of a steel or aluminum frame in the shape of a circular plate with holes. The central circle (7) has a diameter slightly larger than the central axis (5) and has a square opening. At least 6 slots are included: the outer slot (8) used for placing the media base (4) and the inner slot (9). There is a lock (3) to lock the media base (4) so ​​that it does not move. At the bottom of the steel frame (6) there is an inner base (15). It is in the form of a rod or tube and is shaped into a circle with a diameter larger than the circle in the center (7). Attached next to the central circular opening (7), the outer surface of this inner base (15) has a grooved appearance. The gear which is aligned with the teeth on the timing belt (10) is attached to the inner base (15). And the other end of the belt loop is connected to the gear reducer (11) which supports the transmission of the rotational power. From the motor (12) - Media base (4) serves as a learning medium for each lesson. It is in the form of a board of size Slightly larger than the outer circumference slot (8). Installed by placing it in the same position as the outer circumference slot (8). The bottom surface of the media base (4) has magnets attached for attaching to the media base lift. The top surface of the media base (4) has 3D models (13) and pin art (14) are installed, which are held in place. Secured with nuts and screws to prevent movement. - Three-dimensional mannequins (13) are mannequins that depict dance or choreography, and are created by experts in the field. Thai dance or performing arts serve as a model for creating three-dimensional models (13) in dance and performing styles. Various topics in each lesson. - Pin art relief media (14) consists of many pins arranged together, shaped like Three-dimensional model media (13) in the same pose in each lesson. The control equipment consists of: - The control box (26) has a trapezoidal shape, on the top of the control box lid. The control (26) consists of three buttons: the left button (22) is the back button, the middle button (23) The button is for start or repeat. The right button (24) is for next. It is located in the center of the lid and has an LED screen (27) that displays it. The machine's operation is located in the lower left corner. There is a handle (28) located next to the left button (22) and Right button (24) both left and right for the visually impaired to maintain balance. Front cover of the device box. Control (26) has a switch (29) installed for turning on and off the operation and the side cover of the equipment box. Control (26) Install ventilation fan (30) for use in cooling. - Audiobook (19) installed inside the control box (26) contains dance lesson content. Or dance moves in audio file format. Store and play audio files from a secure storage memory card. Digital Card or SD Card) which controls the playback of audio files through a microcontroller control program (20) And there is a speaker (32) mounted on the side of the control box (26) that amplifies the sound. - The control unit consists of a microcontroller (20) and limit switches (Limit Switch) (21) which has a control panel circuit and programming to control the operation of Motor (12) and linear actuator (18) to control the rotation of the steel frame (6) and The media base (4) includes the playback of audio files of the audiobook (19) in each lesson to work in conjunction, which The programmed microcontroller (20) receives data from the three buttons. The left button (22) The center button (23), the right button (24) and the limit switch function as electrical circuit opening and closing devices. By specifying the position of the steel frame rotation (6) and raising the media base (4) through the transmission of signals, control the Rotating Motor (12) and Linear Actuator (18) Cover (2) has a shape of a round or hexagonal cover and is less wide than the raised edge of the base. The main structure (1) is slightly smaller so that it can fit together. There are holes drilled in the top of the cover. and closed with a top cover (25) in which the hole is slightly larger than the media base (4) to provide a space for Media base (4) is raised high above the cover so that learners can touch each dance or movement in each lesson on The media base (4) can be safely placed, not come into contact with other lessons during the lesson, and not be bumped or hit. During the transition to the next lesson, the holes that are drilled when not in use have a cover on top (25) to prevent them from The internal components are damaged.
