  • Publication number: 20260183670
    Abstract: This disclosure relates generally to a method and system for enhancing fine-motor skills based on adaptive thresholding. The disclosure relates to an assistive system to improve the fine motor skills of specially abled children through a gamified format. The conventional methods are repetitive and disengaging, which use rule-based threshold changes which do not help in developing fine-motor skills. The disclosed system uses rotational and translational movements detected via accelerometer and gyroscope sensors comprised in a wearable device and applies adaptive thresholding to perform various actions in a first-person controller (FPC) game environment. The disclosed method uses dynamic thresholding concept for adjusting maximum and minimum sensor readings. The method computes threshold values which are computed based on previous readings and predicted user improvement values from a regression model.

  • Publication number: 20260114806
    Abstract: Existing therapeutic methods lack interactivity and adaptability to individual needs. The present disclosure retrieves from a database, a hardware component design as an interactive table comprising a grid of sensor(s) to detect input(s) from a user. The detected one or more inputs from user are passed to a gaming engine connected to the hardware component. Reflex time of user is recorded, when user provides the inputs to the sensors. Reflex time is compared with predefined time Tn and at least one of following is performed based on comparison that includes incrementally changing position of object, resetting timer, increasing timer with a first delta value and moving position of object closer to initial position with a second delta value. An average response time, a progression metric and adjustments to timer are calculated. A cognitive function to assess the severity of cognitive decline of user is derived.

  • Patent number: 11992745
    Abstract: Good health is one of the paramount essentials for any human being. A method and system for assessing and improving wellness of a person using body gestures have been provided. The system is configured to address fitness, wellness and physical movement related problems for both the abled and the differently abled society. The disclosure provides an intelligent and adaptive system that will comprehend the gestures and postures of the person to assess his capability of undertaking wellness activities. The person's movement capabilities and the environment are learnt by the system to track the gestures for the activities. Based on his gestures, the extent of activity achievement is calculated. The system also has the feature of provisioning dynamic activities to the person based on prior attempts and levels of achievements. Additionally, the system also providing the fitness routine in an AR environment by human-to-object mapping through object detection and augmentation.
