Paragraph 7 refines the central idea by describing the transformation of the neurofeedback technology into smart glasses, expanding its application beyond video games to real-life tasks.
The detail from paragraphs 6-9 that refines the central idea is found in paragraph 7, which explains how the Grecos shifted from video games to real-life activities by applying neurofeedback technology to smart glasses. The passage states, "In the months before Domenic's death in 2013, the father-son team came up with a solution: apply the same neurofeedback technology to smart glasses that users could wear while performing any task at all. The glasses would darken as the user became distracted, providing a real-time incentive to stay focused."
This detail refines the central idea by illustrating the progression of the technology from video games to a more practical and versatile application in the form of smart glasses. It highlights the innovation and evolution of the neurofeedback technology developed by the Grecos, emphasizing the transition from a gaming-focused approach to a broader integration into everyday tasks. The use of smart glasses with real-time feedback aligns with the central theme of the passage, showcasing a novel approach to enhancing concentration and focus in various activities.
