Meta Platforms has two headset prototypes that caused a stir at SIGGRAPH 2025 last week in Vancouver. Boba 3 features an ultrawide 180- degree horizontal by 120-degree vertical field of view, with 4K LCDs achieving 30 pixels per degree (PPD). Human vision is approximately 200×135 degrees, while the Quest 3 offers less than 110×96. The other device, Tiramisu, touts 90 PPD — 3.6x the pixel density of the Meta Quest 3 — and aims for “a new milestone for realism in VR.” The prototypes are the latest steps on Meta Reality Labs’ “mission to pass the visual Turing test” by creating “virtual experiences that are indistinguishable from the physical world.” Continue reading Meta Reveals Its Latest VR Headset Prototypes at SIGGRAPH

Microsoft, Google and Facebook are all pursuing chatbots, which will function as virtual assistants, answering questions, responding to requests, and anticipating needs. But building functioning chatbots, which are based on artificial intelligence, is harder than it sounds. To further progress, Google open-sourced one of its natural language tools. Although Facebook hasn’t yet open-sourced it, the company introduced DeepText, a natural language engine that it is just beginning to use with its own services.
