Spatial computing is transforming sales through digital twins and augmented reality, which eliminate "imagination friction" by offering immersive 3D experiences. These technologies boost engagement by 300% and provide "revealed intent" data through sophisticated gaze and movement tracking. This shifts lead generation toward behavioral observation, significantly accelerating complex B2B sales cycles. However, collecting biometric and physiological data introduces massive legal risks regarding neuro-rights and cognitive privacy. Companies must implement robust governance and granular consent to navigate emerging global regulations. Success depends on balancing these powerful technical capabilities with ethical data stewardship, ensuring that immersive sales tools don't become multimillion-dollar liabilities.
