    University students using a closed circuit television (CCTV) system improved reading speed. Active CCTV users showed greater gains than passive users and those without CCTV, highlighting its effectiveness as a reading aid.

    Area of Science:

    • Ophthalmology
    • Educational Psychology
    • Human-Computer Interaction

    Background:

    • Reading aids are crucial for individuals with visual impairments or reading difficulties.
    • Closed circuit television (CCTV) systems offer adjustable magnification and contrast, potentially aiding reading.
    • Understanding the factors influencing CCTV effectiveness in reading is essential for optimizing its use.

    Purpose of the Study:

    • To investigate the essential factors contributing to effective reading using a closed circuit television (CCTV) system.
    • To compare the reading speed improvements of active CCTV users, passive CCTV observers, and a control group without CCTV.

    Main Methods:

    • A study involving thirteen university students (6 male, 7 female) with normal vision (20/20).
    • Participants were trained in reading using the CCTV system over five sessions, with active and passive observer roles.

  • A control group trained without CCTV used the same reading materials (Thurstone Reading Kit).
  • Pre- and post-training reading speed (words per minute) was assessed.

    • Main Results:

    • Active CCTV users demonstrated the most significant increase in reading speed.
    • Passive CCTV observers showed moderate reading speed improvements compared to the control group.
    • The control group, trained without CCTV, exhibited the least improvement in reading speed.

    Conclusions:

    • Active engagement with the CCTV system is a key factor in enhancing reading speed.
    • CCTV technology can be an effective reading aid, with active use yielding superior results.
    • Further research is recommended to explore additional factors and applications of CCTV in reading assistance.
