Embodiments pertain to a system for providing a user with a lesson for creating an object of the visual arts. The system may include at least one processor; and at least one memory configured to store data and software code portions executable by the at least one processor to allow the execution of the following steps: receiving an image of at least one user-created intermediate artwork and/or assistive feature relating to an artwork. The steps may further include analyzing the image of the at least one intermediate artwork and/or assistive feature; and providing feedback on the at least one intermediate artwork and/or assistive feature.

An operating method of an interactive service platform including the steps of: communicating with a plurality of user end devices via an application software; receiving physiological measurement information of user from the user end devices via the application software; analyzing the physiological measurement information to identify a physical and mental state/lifestyle of an associated subscriber; and automatically responding content information associated with at least one associated subscriber according to requests from the user end devices.

Apparatus for aiding learning by a person comprises a cover or shield (1) for concealing from the person a part of the person's body, and a webcam (6) and a screen (10) for visually displaying to the person, during concealment of the concealed body part, images of a part of the person's body not in direct view of the person. The apparatus may be used in the learning of a skill, such as hand-writing. In another embodiment, the shield is a collar worn to conceal part of the wearer's body, and the webcam and screen display the concealed body part in real time to the wearer. This apparatus can be used in many applications, such as to learn sports activities or to correct body image, posture or movement.

An attachment for a writing instrument, comprising a support member comprising a distal end (D) and a proximal end (P), wherein an attachment axis (A) is defined between the distal end and the proximal end, wherein the support member is configured to be attached to a writing instrument, an inertial measurement unit, wherein the inertial measurement unit is configured to measure a movement of the attachment axis (A) between a first and a second position of the attachment axis, a momentum wheel assembly, wherein the momentum wheel assembly comprises a first rotatable member coupled to a first motor, wherein the first motor is configured to apply a variable torque to the first rotatable member, and a control unit configured to actuate the first motor based on the movement of the attachment axis measured by the inertial measurement unit.

An apparatus and method for training writing position can be implemented in the form of a glove with fasteners that secure a thumb, forefinger and middle finger together in a desired writing grip position. A protrusion can be applied to an outer lateral portion of the user's writing hand between a pinky finger and a wrist area, which can be mounted on a glove worn by the user, to prop up the writing hand of the user at a desired angle for writing. The protrusion can be implemented in the form of a ball that is fastened to the outer lateral portion of the glove worn on the writer's hand. The glove can be configured to be customized for a given user, such as by selecting a desired glove size, fastener position and/or position of a protrusion on the outer lateral portion of the glove between the pinky finger and the wrist. The glove is potentially useful for training a desired writing position of the user's writing hand as may be helpful in overcoming some of the challenges related to dysgraphia.

Disclosed is a method of using the progressive color scheme such as a rainbow color order to represent the writing stroke order of the Chinese type character. In addition it discloses a method that uses dots to indicate the starting point of each stroke and a method to indicate which strokes belonging to the radical of the Chinese character and which strokes belonging to the remaining parts of the character by different colors of these dots.

An improved machine learning system is provided. For example, a content management server may provide a digital assessment of a user's handwriting to assess the user's knowledge of a language. The assessment may comprise adaptive technology to help determine initial questions to provide to the user as well as follow-up questions to clarify appropriate remediation content in a particular context. The content management server may also provide real-time analysis, including assessing multiple users at the same time in adjusting the assessment based on the digital input from each of these users. In some examples, the content management server may incorporate handwriting analysis methods to perform object detection and score handwriting input.
