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 T n 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.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS AND PRIORITY The present application claims priority to Indian application no. 202421083425, filed on October 30, 2024. TECHNICAL FIELD The disclosure herein generally relates to an interactive game system, and, more particularly, to an elder friendly device to improve hand eye co-ordination using an adaptive gaming technique. BACKGROUND A vast majority of the global population is ageing rapidly. Cognitive decline leads to many conditions including dementia which is a common condition among the elderly; Although the brains of patients with dementia gradually degrade, scientists have found that this degradation is still plastic. Therefore, in addition to slowing down the rate of degeneration with drugs, training can also keep the brain healthy. Further, as the body can be used to strengthen the physique through exercise, and often stimulate the brain to promote cognitive function, the brain can also be trained to improve cognitive function. Cognitive training can also be called brain gymnastics, which may help delay cognitive decline. The conventional way to prevent cognitive decline is usually through similar rehabilitation equipment or a single training mode. The user's single training mode can be used for specific training for a certain cognitive function, if it needs to be diversified. Training various cognitive functions may require more time to perform various training modes and may require frequent visits to professional cognitive training in professional institutions, which can not only be inconvenient, but also impossible to effectively track training progress. Therefore, effective tracking of training progress and conducting preventive training in a convenient manner is one of the urgent problems in the field of cognitive training.
