A virtual reality system with an inspecting function of assembling and disassembling and an inspection method of assembling and disassembling based on virtual reality are presented. A learning-end acquires an inspection data and a teaching assembling-disassembling record being set with a plurality of checkpoints, plays the teaching assembling-disassembling record, modifies a learning assembling-disassembling status of a plurality of virtual objects based on user's operations for assembling or disassembling. The learning-end issues an assembling-disassembling error reminder when the learning assembling-disassembling status is inconsistent with a teaching assembling-disassembling status at any of the checkpoints.

There is disclosed a method and kit providing a crafts experience for a novice artist in assembling a customized belt buckle. The kit may comprise a planar frame, a set of dissimilar inlays each preconfigured for mounting to the frame, a set of fasteners, and instructions. The planar frame may include a raised perimeter, an open center, and a frame channel adjacent to at least a portion of the raised perimeter. The frame channel may be recessed below a front edge of the raised perimeter and include one or more mounting holes. The dissimilar inlays may each include a decorative face mountable flush with the front edge of the raised perimeter. Fasteners may be provided for securing the inlays selected to the frame via the one or more mounting holes. The instructions may direct the novice artist on how to assemble the belt buckle and thereby fulfill the crafts experience.

An integrated system for art examination includes a power module, an information receiving and a storage module, an information processing module, a control module, a display module, a paper printing module, and a paper processing module; the information receiving and storage module is used to receive and transmit an examinees registration information, an examination room information and an on-site identity information to the information processing module; the information processing module is used to verify whether the examinees registration information is consistent with the on-site identity information and transmits a conclusion to the control module; the control module controls the display module, the paper printing module and the paper processing module; the display module is used to display information to guide an exam worker how to operate, and an input of the examinee's on-site identity information is completed on the display module through a human-computer interaction.

A scratchpad creation method and an electronic device are disclosed. The method includes: receiving a first input performed by a user on a target identifier, where the target identifier is associated with a first video file; and displaying a first scratchpad in response to the first input, where the first scratchpad is a scratchpad created based on content of the first video file, the first scratchpad includes at least one video identifier and at least one progress identifier, the video identifier is used to indicate a video clip in the first video file, and the progress identifier is used to indicate completion progress of an operation corresponding to the video clip.

Systems and methods for providing a built-in training capability for a computer application associated with multiple operations. A control icon may be presented along with an image associated with the particular computer application. The control icon may list training tasks that are associated with the particular computer application or the particular image and train a user in performing a particular operation. Based upon a user interaction with the control icon, a training task may be implemented. The training task may comprise multiple steps or actions required to complete the task. The training task may cause a written description of each action and a training icon to be presented to the user. The training task may therefore assist the user in performing the operation associated with the training task.

Devices used to cue a user to take a step when experiencing a walking disorder, such as a freezing of gait episode, are disclosed. The devices are configured to cue the user with a visual and/or audible cue. The devices include an activation module and a cueing module. The cueing module includes a metronome and a laser light source. The devices are mounted on an assistive mobility device or on the user.

An instructional aid device is provided. The device includes a plurality of individual pages which can be fixed or removably secured within a binder or binding. The individual pages include various instructions that can be used for any type of product assembly, directions on a do-it-yourself project, and educational manuals. One embodiment of the instructions is a cookbook that includes recipes for cooking different types of foods. Each instruction page includes a scannable code that is configured to automatically redirect the scanning device, such as a smartphone, to a website that includes instructional information. The device is configured to automatically display parts or ingredient types and amounts in the screen background over time, in order to provide continuous instruction to the user while they are executing a project or preparing the recipe.

A modular and reconfigurable chassis enables minimalization of inventory while facilitating ease of conversion into multiple configurations of a welding simulator. The modular and reconfigurable chassis permits both hardware and software related system configurations. The chassis is adapted to receive hardware interfaces for single and multiple user configurations.

A method is disclosed to ensure that components in a complex system are correctly connected together. In one embodiment, such a method provides a library of previous configurations of a system. The system includes multiple components connected together with cables. The method generates, from the library, instructions for assembling the system by connecting components of the system together with cables. The method receives feedback generated in the course of using the instructions to assemble the system and uses the feedback to refine the instructions. In certain embodiments, a configuration associated with the assembled system is then added to the library. This process may be repeated to further refine the instructions and increase a number of configurations in the library. A corresponding apparatus and computer program product are also disclosed.
