A Gadget That Trains the Brain Muse, a wellness-inspired device from Interaxon, sits against the forehead to detect brain activity while users play meditating games on an accompanying app, aptly named “Calm.” Even calibrating the gadget is like stepping into a scene in “Divergent”: A soothing voice prompts you to think about items pertaining to different categories, no button-pressing or speaking aloud required. The goal: learning to control your own mind for improved relaxation and lessened anxiety. It’s the gift of a sound mind. $299, store.choosemuse.com
