Lightweight Virtual Reality Glasses Use Bluetooth

Virtual reality (VR) glasses such as Oculus Rift (see “Consumer Electronics Take User Interfaces Beyond Your Fingertips” on electronicdesign.com) are pushing high-definition resolutions, but they have been large and bulky.  Dlodlo looks to make VR glasses more stylish with the Dlodlo VR Glasses (Fig. 1) that weigh in at only 4 oz. (120 g). This is significantly lighter than the competition.

Even so, the performance specifications are still impressive. It has 2K+ HD resolution with a 16:9 aspect ratio and supports 4K input. The 120 Hz refresh rate provides a solid image while the 110-deg. field of view (FOV) delivers an immersive, no-border VR experience.

The glasses have a Bluetooth 4 with BLE (Bluetooth Low Energy) support. They can handle hosts up to 10 m away. The 2000 mAh battery delivers about three to four hours of continuous use. There is a Micro USB 2.0 OTG interface and stereo headphone connection. A built-in microphone will come in handy for VR conferences or multiplayer gaming.

The glasses are priced at $699.

The availability of a low-cost, high-resolution VR platform could have a major impact for VR applications from gaming to architectural virtual walkthroughs. The wireless connection can work with a range of devices from Android smartphones to PCs.
