Introduction to VR... what is VR?
Virtual Reality (VR) immerses users in a computer-generated environment, making them feel like they are physically present in that space. It typically involves the use of VR headsets and may include additional hardware like hand controllers and motion sensors to enhance the experience.
History and Development of VR
The concept of VR began in the 1950s with Morton Heilig's Sensorama in the 1950s, offering a multi-sensory experience. Ivan Sutherland's "Sword of Damocles in the 1960s was the first head-mounted display.
The 1980s and 1990s saw significant progress with Jaron Lanier's VPL Research pioneering VR gear which helped lay the groundwork for modern VR systems. Lanier is known for his research and development in VR, including his creation of the term "virtual reality" and his development of early VR hardware and software.
His company, VPL Research, was one of the first to develop VR gear, including the DataGlove and the EyePhone. The DataGlove allowed users to interact with virtual environments through hand movements, while the EyePhone was an early head-mounted display. Lanier's contributions were crucial in demonstrating the potential of VR technology and influencing its future development.
VR technology stagnated for a few years before the 2010s brought a resurgence with devices like Oculus Rift, HTC Vive, and PlayStation VR, making VR more accessible.
Coding for VR: Game Engines and Software Frameworks
Coding for VR games is extremely detailed and in-depth, consisting of multiple levels of code that needs to work together dynamically. To achieve this efficiently, We only need to look towards the programming libraries that were built for years to handle the specific needs of VR, game engines.
Game engines are vital for VR development, providing essential tools and functionalities. Read more about game engines here if you are unfamiliar with the subject.
Unity and Unreal Engine are popular choices, supporting languages like C#, C++, and JavaScript. VR Software Development Kits (SDKs) like Oculus SDK and SteamVR offer the necessary libraries and APIs for building VR applications.
3D modeling software like Blender and Maya is used to create immersive environments and assets that can be interacted with and manipulated in real time by the user, usually with life-like physics.
Downsides and Current Challenges
Despite its potential, VR faces several challenges:
- Motion Sickness: The disconnect between visual motion and physical movement can cause varying levels of discomfort and nausea for users.
- Cost: High-quality VR systems remain expensive, usually costing anywhere from a few hundred dollars to upwards of a thousand.
- Content Development: Creating high-quality VR content is very resource-intensive for gaming companies and even more so for solo developers.
- Accessibility: Making VR accessible to people with disabilities is challenging considering the possible health risks.
Future Updates and Haptic Feedback
To combat these challenges, advancements are being made in hardware and software.
- Higher resolution displays: Newer VR headsets are incorporating higher resolution displays, which improve visual clarity and reduce the screen door effect (a grid-like pattern seen in some VR headsets).
- Better tracking system: Improved tracking systems are being developed to enhance accuracy and reduce latency. This includes advancements in inside-out tracking, which uses cameras on the headset to track movement, eliminating the need for external sensors.
- More Ergonomic Headsets: VR headset designs are becoming more comfortable, with better weight distribution, adjustable straps, and improved ventilation. This helps reduce fatigue and discomfort during extended use.
- Haptic Feedback: [Haptic feedback technology](https://en.wikipedia.org/wiki/Haptic_technology#:~:text=Haptic%20feedback%20(often%20shortened%20to,of%20one's%20hand%20or%20fingers.) is being integrated into VR controllers and accessories to provide more immersive tactile experiences. This includes advanced vibrations, force feedback, and even full-body haptic suits. Overall, the VR industry is making significant strides to address these challenges, and ongoing innovation is likely to continue improving the VR experience for users.
