A pen-spinner fidget device is provided. The device is a multifunctional device designed as both a fidget toy and a holder for writing instruments, comprising a body shaped to resemble a pistol grip for enhanced ergonomics and comfort. The device's body includes an integrated grip with finger grooves and textured surfaces, ensuring a secure hold that is resistant to slippage and strain, particularly during extended use. At the top of the device, a flexible fastener holds a writing utensil, allowing it to spin freely around a rotation point, typically a ball-and-socket joint, enabling multidirectional movement for fidgeting. This spinning mechanism provides a stress-relieving, repetitive motion that mimics traditional fidget spinners, supporting focus and relaxation. Additionally, the invention outlines a method for use, where users secure a writing utensil in the fastener and engage in rotational motion, which can aid in concentration and reduce anxiety during focused activities.

An apparatus and method of controlling a repetitive motion linear actuator (RMLA) accepts a minimum repetition rate and a commanded repetition rate. If the commanded rate is greater than the minimum rate, the RMLA automatically operates in a speed scaling mode by continuously applying the cycles and scaling the cycle length to provide the commanded rate. If the commanded rate is less than the minimum rate, the RMLA automatically operates in a dwell mode by fixing the cycle length and discontinuously applying the cycles, while adjusting a separation between the cycles to provide the commanded rate. In dwell mode, the cycle length can be equal to its maximum allowed value Tmax, or can equal a desired value less than Tmax. The cycle can have any profile shape, such as a sinusoidal shape or a shape that includes periods of deceleration and acceleration separated by constant speed periods therebetween.

When comparing and analyzing multiple recordings of repetitive movements, there is no means to dynamically switch the reference point for synchronized playback. Therefore, it was difficult to recognize the discrepancies between movements that appeared different depending on the selection of the reference point, and to identify their causes. [Solution] The system accepts multiple time-series media data, each recording multiple repetitive actions, with multiple reference point candidates assigned to each recording. It displays these data in parallel or superimposed, and presents the reference point candidates on a timeline. For each type of reference point candidate, the system calculates the median time position across multiple recordings as the representative position, and sets intervals on the timeline using the midpoint between adjacent representative positions as boundaries. The system designates the reference point candidate corresponding to the interval to which the user's input location belongs as the reference point, and realigns all recordings to the time position of that reference point to update synchronized playback.
