- Hallucinations: The AI model can produce bizarre or incorrect answers, which may lead to misinformation or confusion.
- Privacy Concerns: While SARAH prioritizes user privacy, the use of cameras and microphones can raise privacy and security concerns.
These limitations suggest that SARAH should be used as a complementary resource and not as a substitute for professional medical advice or in-depth health information.
What Issues Does SARAH Encounter?
SARAH has encountered several issues in its implementation, stemming from its reliance on AI technology and its developmental stage. These issues affect the chatbot’s reliability and the quality of information it provides.
Accuracy and Hallucinations
SARAH’s accuracy is limited due to its AI training, which can cause it to provide incorrect or outdated information. Hallucinations, where the AI generates bizarre or nonsensical responses, pose a risk of misinformation. This issue requires users to verify SARAH’s advice with other reliable sources to avoid potential confusion or harm.
Lack of Depth and Scope
SARAH’s responses often lack depth and are restricted to WHO’s purview. The chatbot is not equipped to discuss specific drugs or provide detailed medical advice. This limitation means that SARAH often redirects users to external resources or suggests consulting healthcare professionals for more complex issues.
Technical Limitations
SARAH may encounter technical limitations that affect its functionality. The AI model used for training might not always be up-to-date, leading to a lack of current information. Additionally, SARAH might not be able to answer certain questions, indicating a need for further training and development.
How Does SARAH Ensure User Privacy?
SARAH prioritizes user privacy and follows strict guidelines to protect personal information. The chatbot’s design includes several measures to ensure that user interactions are secure and anonymous. Here are the key privacy measures employed by SARAH:
Anonymous Sessions: Each interaction with SARAH is anonymous, and the chatbot does not retain personally identifiable information.
Data Deletion: SARAH deletes facial expression data after 30 seconds, ensuring that sensitive information is not stored.
Privacy Regulations: SARAH complies with WHO’s privacy practices and follows regulations to ensure that user data is protected.
Limited Data Access: Government partners and researchers do not have regular access to user data unless they request voluntary survey data, adding an additional layer of security.
Secure Communication: SARAH uses secure communication channels to protect against unauthorized access and cyber threats.
These privacy measures aim to ensure that SARAH provides a safe and secure environment for users, reducing the risk of privacy breaches and ensuring that users can interact with the chatbot without compromising their personal information.
How Can Users Give Feedback?
User feedback is vital for SARAH’s development, enabling the World Health Organization (WHO) to identify areas for improvement and address potential issues. The feedback process provides users with various avenues to share their experiences, opinions, and suggestions for making SARAH more reliable and user-friendly. Here are the primary ways users can give feedback about SARAH:
Surveys and Questionnaires: WHO occasionally distributes surveys to gather user feedback on SARAH’s performance and effectiveness. These surveys allow users to share their experiences and suggest improvements.
Official Contact Channels: Users can provide feedback directly to WHO through its official communication channels, such as email or phone. This direct contact allows for more detailed feedback and specific concerns to be addressed.
