1. Clarity and recognizability: choose a photo with high clarity and make sure that the features of the senior's face are clearly visible in the photo, which will make it easy for others to recognize and identify them on platforms such as social media.
2. Friendly, approachable and easy to understand: choose a friendly and approachable avatar picture, which can be a picture of an elderly person with a smile on his/her face, so that it will give people a friendly and approachable feeling.
3. Respectful and professional: If the older person is using the headshot in a professional scenario, such as a job or business requirement, choosing a formal, professional photo will make it look more credible and professional.
4. Conformity to personal interests: Respecting the interests and preferences of seniors, you can choose a photo as an avatar that represents their hobbies and interests, for example, seniors who like to travel can choose a photo of themselves on a trip.
