This study investigates the complex interplay between public sentiment, as captured through news titles and descriptions, and the stock prices of three major tech companies: Microsoft (MSFT), Tesla (TSLA), and Apple (AAPL). Leveraging advanced analytical methods including Pearson correlation, wavelet coherence, and regression analysis, this research probes the degree to which stock-price fluctuations can be attributed to the polarity of media sentiment. The methodology combines statistical techniques to assess sentiment's predictive power for stock opening and closing prices, while wavelet coherence analysis unveils the temporal dynamics of these relationships. The results demonstrate a significant correlation between sentiment polarity and stock prices, with description polarity affecting Microsoft's opening prices, title polarity influencing Tesla's opening prices, and a positive impact of title polarity on Apple's closing prices. However, Tesla's stock showed no significant coherence, indicating a potential divergence in how sentiment affects stock behavior across companies. The study highlights the importance of sentiment analysis in forecasting stock-market trends, revealing not only direct correlations but also lagged influences on stock prices. Despite its focus on large-cap tech firms, this research provides a foundational understanding of sentiment's financial implications, suggesting further investigation into smaller firms and other market sectors.

The perspective o f our review evaluated the interaction o f cerebral palsy with eye-gaze interaction, the main tool of assistive technology, supporting communication and personal development fo r degrees o f disability that involve motor impairment. Purpose: Bringing in the main field, alternative possibilities from the literature fo r better integration o f the disabled. Methods: Systematic review. Results: We revealed the substantial impact o f assistive technology on cerebral palsy patients, grade o f integration, easing caregiver's dedication, the devotion o f training and the companionship being vital to reduce the level o f abandonment. Conclusion: Primordial eye-gaze interaction initiated the idea o f infrared eye-trackers fo r better solutions in the field o f communication, personal interaction with others, personal development and even employment. The eye-tracking industry has its popularity costdepending, fo r the present, being in the range o f expensive fo r disabled people. For cerebral palsy, eyegaze has little steps, but with a crucial impact on quality o f life. [ABSTRACT FROM AUTHOR]
