A simple example is Instagram filters, which overlay effects on your vision through smartphones. VR requires devices specific devices, such as the Oculus Rift, for complete immersion.
| Feature | Virtual Reality | Augmented Reality |
|---|---|---|
| Environment | Replaces the real world | Adds elements to the real world |
| Devices | Headsets, haptic gloves | Smartphones, special glasses |
| Examples | Oculus Rift, HTC Vive | Instagram Filters, Microsoft HoloLens |
History of Virtual Reality
The journey of immersive technology began much earlier than many imagine. From the first experiments to the devices modern, the development this area has been marked by innovations and visionary pioneers.
Origins and evolution
The concept of virtual environments dates back to the 19th century, with Charles Wheatstone's stereoscope. This device created the illusion of depth, a fundamental principle for virtual reality. In the 1960s, Morton Heilig developed the Sensorama, a machine that offered multisensory stimuli, including sight, sound, and even vibrations.
In the 1980s, VPL Research commercialized the first digital helmets and gloves, marking the beginning of mass production of devices immersive. These projects paved the way for the technologies we know today.
Important milestones in technology development
THE development The rise of immersive technology has had several key moments. In 1950, the U.S. Air Force created the first flight simulators, which used immersive principles for training. In 2012, the Oculus Rift was launched via Kickstarter, revolutionizing the market with its accessibility.
In 2016, the HTC Vive introduced full-environment tracking, allowing users to move freely in virtual spaces. More recently, in 2023, the PlayStation VR 2 introduced 2000x2040 resolution and eye tracking, taking the experience to a new level.
