Abstract
This paper introduces PillowTalk 2.0, a device that allows users to record their dreams upon waking through intuitive, low-effort methods. A 30-day study involving six participants evaluated three activation modalities: squeezing, pulling, and voice commands. Voice activation eliminates the need to locate the device, making it easy to use, particularly in low-visibility situations, but it may disturb a sleeping partner and can be difficult for users immediately upon waking. Squeezing was appealing due to its intuitive, comforting nature, fitting the intimate act of recording dreams, though accidental activation during sleep was a concern. To address this, future designs will focus on preventing unintentional activation while ensuring the squeeze point is easy to identify, potentially through a specific squeeze pattern. The study demonstrates PILLOWTALK 2.0’s potential to support dream capture in a natural environment, with future iterations exploring personalization and AI-driven dream recall prompts during REM sleep stages to enhance user experience.
