Summary:

• **SlimeVR Butterfly Trackers Help You Move in Virtual Reality** - SlimeVR has created special small devices called "Butterfly Trackers" that you wear on your body to play VR games. These trackers use a chip called the nRF52833 and can last up to 48 hours on one battery charge, so you can play for a really long time without needing to recharge them.

• **Full Body Movement in VR Games** - These trackers let video game players move their whole body naturally in virtual reality games, not just their hands and head. This makes VR games feel more real and fun because the game can see where your arms, legs, and body are moving.
