CLIP-Gaze: A Novel Framework for General Gaze Estimation via Visual-Linguistic Model

Q: How can CLIP-Gaze be adapted to handle additional gaze-irrelevant factors beyond appearance, wearable, and image quality

CLIP-Gaze can be adapted to handle additional gaze-irrelevant factors beyond appearance, wearable, and image quality by expanding the scope of language descriptions used to construct gaze-irrelevant features. By incorporating a more comprehensive set of factors into the prompt templates, such as environmental conditions, facial expressions, or even external distractions like mobile devices or background movements, CLIP-Gaze can capture a wider range of potential disturbances that may affect accurate gaze estimation. This approach would involve enhancing the diversity and specificity of language prompts to encompass various real-world scenarios where gaze estimation is crucial.

Q: What are the potential ethical implications of using advanced AI models like CLIP in real-world applications such as driver monitoring systems

The use of advanced AI models like CLIP in real-world applications such as driver monitoring systems raises several ethical implications. One major concern is privacy infringement due to the extensive data collection required for training these models. The utilization of sensitive personal information for gaze tracking purposes without explicit consent could lead to privacy violations. Moreover, there are concerns about algorithmic bias and discrimination if the model's predictions disproportionately impact certain individuals based on demographic characteristics or other factors. Transparency regarding how CLIP-Gaze operates and ensuring accountability for its decisions are essential to mitigate these ethical risks.

Q: How might the integration of language descriptions impact the interpretability and explainability of the gaze estimation process

The integration of language descriptions in the gaze estimation process through CLIP-Gaze may have both positive and negative impacts on interpretability and explainability. On one hand, using language prompts can provide context and insights into why certain features are deemed relevant or irrelevant for estimating gaze direction. This linguistic input can enhance human understanding of the model's decision-making process by offering explanations in natural language terms. However, relying on complex vision-language interactions might introduce challenges in interpreting how specific words or phrases influence the final output. It could make it harder to pinpoint exactly which aspects of an image contribute most significantly to the estimated gaze direction since this information is embedded within a multimodal representation learned by CLIP. Overall, while integrating language descriptions enhances interpretability at a high level by providing contextual clues, it also introduces complexities that require careful consideration when aiming for full transparency and explainability in AI-driven systems like CLIP-Gaze.
