As the main use case (60%) , responses feature a close-up view of a facial expression or a gesture of a viewer.
People show both positive and “teasing” emotions.
“Max makes a strange face. But I don’t think he dislikes the photo.”Inga (G4)
“I agree with that outfit. Go ahead and buy it.” Ada (G3)

Genre: Connection to remote contexts
14
In 30% cases, videos feature context of a photo viewer, which intends for a comparison with that of the photo taker.
Some videos focus on content similar to the photo.
“We have more fun than you do!”Maria (G3)

Genre: Augmentation of present scenes
15
As a niche genre (10%), videos feature other events taken in the same scene as the photo.
Most often is monologue rather than collaboration between users.

Positive: Personal & always-together
• Seeing real and personal reactions.
“It is like you see a friend. You get the enthusiasms...”
Related genre: Display of momentary expressions
• Make a group feel they are always together.
“The feed-back connects the photo taker and others.”
Related genre: Connection to remote contexts

Negative: Relevance, quality & control
17
Couples living together see lower value in sharing their emotion responses.
Problems with “big faces” videos using front camera.
Some users were not at ease with the automatic nature of the video recording.
Summary
Front-camera videos serve as emotion responses to shared photos, especially for dispersed , close-knit, young users.
Emotion responses are used to share contexts with remote partners for a sense of co-presence.
As feedback mechanisms, emotion responses are more personal and expressive than comments and like buttons.
