    Area of Science:

    • Human-Computer Interaction
    • Assistive Technology
    • Computer Vision

    Background:

    • Supporting independent living for seniors with dementia requires intuitive and easily understandable instructions.
    • Traditional methods may not effectively convey spatial information for daily tasks.
    • Visual aids are crucial for cognitive support in this demographic.

    Purpose of the Study:

    • To propose and evaluate a novel work step indication method using grid-pattern projection.
    • To enhance the ability of individuals, particularly seniors with dementia, to perform daily tasks independently.
    • To create a visually intuitive system for spatial instruction delivery.

    Main Methods:

    • Utilized a projector, range image sensor, and camera to capture 3D scene geometry.
    • Developed a method for directly projecting a grid-pattern onto the target environment.
    • Implemented a prototype system to demonstrate the proposed technique.

    Main Results:

    • The grid-pattern projection method effectively indicates spatial instructions for work steps.
    • Direct projection allows for easier association of instructions with surrounding objects.
    • The implemented prototype confirmed the system's usability and clarity.

    Conclusions:

    • Grid-pattern projection offers a promising solution for visually supporting daily work steps.
    • This technology can significantly aid individuals requiring assistance with task completion, promoting autonomy.
    • The method provides a clear and spatially relevant way to deliver instructions.
