TipsyBadge: Wobble Mode and Visual Distortions
A showcase of the TipsyBadge electronic badge, exploring optical manipulation, custom sensors, and interactive firmware effects.
Summary
Hardware developers showcase the TipsyBadge at DEF CON 33, an interactive electronic badge that uses Galvanic Vestibular Stimulation (GVS) to physically manipulate the wearer's sense of balance and spatial orientation [00:05]. The creators explain how low-amperage electrical currents applied behind the ears interact directly with the vestibular nerve in the inner ear.
The demonstration walks through calibration and engages "wobble mode," showing how varying current levels cause an involuntary physical tilt or stumble while walking, simulating intoxication without chemical substances [01:00, 01:58]. The developers describe how the vestibular system couples with ocular reflexes to produce harmless horizontal nystagmus (involuntary eye twitches) [02:49], and demonstrate an onboard color-matching Stroop effect puzzle game played while experiencing vestibular distortion, noting that badges are available at the Hacker Warehouse booth for $100 [03:51, 04:54].
