Historical Case : The Shaker is derived from the paper, 'Feather, Scent, and Shaker: Supporting Simple Intimacy' by Rob Strong and Bill Gaver. This design facilitates a form of interaction that is both subtle and emotional, relying on haptic feedback to convey feelings such as affection, excitement, or calmness. The Shaker prototype is a strong example of affective communication and embodied interaction, concepts that highlight non-verbal, emotional exchange. 

Shaker emphasizes affective communication, which focuses on conveying emotions through non-verbal means. Unlike traditional communication tools that use language or symbols, Shaker employs physical vibrations to express moods. This aligns with Norman’s emotional design framework, which suggests that devices should provide an experience that resonates emotionally with users at the behavioral level. The tactile feedback from Shaker allows users to feel connected to one another without the need for explicit verbal exchange, embodying emotional expression through simple gestures.

Shaker also leverages embodied interaction, a concept highlighted by Dourish, where interaction is rooted in physical engagement. Shaker invites users to communicate through gestures, providing a tactile experience that mimics the physicality of face-to-face interaction. This embodied communication creates a sense of closeness and presence, even when users are physically distant.
