1.1 Introduction
Virtual Reality (VR) refers to a computer-generated environment that simulates real or imagined settings, allowing users to interact with it in a seemingly real or physical way through special electronic devices such as headsets, gloves, and controllers. This immersive experience can involve sight, sound, and even touch, providing a sense of presence within the virtual environment (Burdea & Coiffet, 2003). Similarly, in healthcare, VR is being leveraged for pain management and surgical training, where simulations help practitioners hone their skills in a risk-free environment (Moorhead, 2015). As the world embraces the digital transformation, VR is anticipated to play a significant role in reshaping the future of human-computer interaction, facilitating both professional and personal advancements. However, despite its growing relevance, VR continues to face challenges such as affordability, accessibility, and the need for further technological improvements to enhance user experiences (Freeman et al., 2017).
As a prelude to other parts of this study, this chapter will discuss the background upon which this study was initiated, the statement of problems that led to this study, the Aim and Objectives of the study. Others are Significance of the study, Scope of work, Limitation of the study and Definition of technical terms.
1.2 Background of Study
Virtual Reality (VR) has evolved over several decades from a conceptual idea to a transformative technology with widespread applications. The idea of creating immersive, computer-generated environments can be traced back to the mid-20th century. The term "Virtual Reality" was coined in the 1980s by Jaron Lanier, a researcher who is often credited with popularizing the technology (Lanier, 1989). However, the roots of VR can be found in earlier developments such as the invention of the flight simulator in the 1920s, which allowed pilots to experience simulated environments for training purposes (Hendrix & Barfield, 1995).
In the 1960s, Ivan Sutherland's creation of the first rudimentary VR system, the "Sword of Damocles," marked a key milestone in the history of VR. This early system used a head-mounted display (HMD) and allowed users to interact with virtual objects, although the experience was limited by technological constraints (Sutherland, 1968). In the 1980s and 1990s, advancements in computer graphics, motion tracking, and sensory input devices led to the development of more sophisticated virtual environments. During this time, VR gained significant attention in the entertainment industry, particularly for its potential in video gaming and interactive simulations (Bower & Jaffe, 1992). The early 2000s saw a shift in the application of VR, moving beyond entertainment and into professional fields such as medicine, education, military, and engineering. In medicine, VR has been utilized for surgical training, rehabilitation, and pain management (Rizzo et al., 2011). In education, VR has been used to create immersive learning experiences that are more interactive and engaging than traditional teaching methods (Bailenson, 2018). The military also adopted VR technologies to provide simulated training for soldiers in high-risk environments (Cobb et al., 2001).
Today, Virtual Reality has seen a tremendous growth in both consumer and professional sectors. With advancements in hardware such as the HTC Vive, PlayStation VR, and Oculus Quest, the technology is being adopted in various industries for purposes such as medical simulation, architectural visualization, virtual tourism, and more. Moreover, VR is becoming a vital tool in mental health treatment, with applications for phobia therapy, PTSD, and anxiety treatment (Freeman et al., 2017). As virtual reality technology continues to improve, its potential applications seem limitless, and it is expected to play a significant role in reshaping how humans interact with digital environments in the years to come.
As VR technology has continued to improve, with the advent of more affordable and accessible hardware, the applications of VR have expanded further. Today, VR is a growing field in research, business, and consumer markets. The technology is now integral to areas such as virtual tourism, real estate, design, and even social interaction, with platforms like VR chat and Oculus offering immersive social experiences (Freeman et al., 2017). However, despite its widespread use, challenges remain, including the need for further technological advancements, such as improving the resolution of displays, reducing latency, and increasing user comfort to make VR a more seamless experience (Slater & Wilbur, 1997).
1.3 Statement of Problems
Investigation revealed that the development and adoption of Virtual Reality (VR) is not without its challenges, particularly in the context of its integration into various sectors such as education, healthcare, and entertainment. One of the primary issues is the technological limitations of VR systems, which often hinder its full potential. Although advancements in hardware have made VR more accessible, the technology is still not as refined as required for a truly immersive experience. For example, the visual and auditory quality of VR environments is often limited by the resolution and processing power of the devices, which can lead to discomfort, such as motion sickness or fatigue, during extended use (Jerald, 2015).
Additionally, there is a lack of standardized content and platforms for VR. The creation of VR experiences typically requires specialized knowledge in 3D modeling, programming, and system integration, making it difficult for mainstream content creators to develop for VR. The absence of a universally accepted platform complicates the scalability and consistency of VR applications. As a result, content remains fragmented, limiting the interoperability of VR systems and experiences (Harris, 2019).
Furthermore, concerns regarding the social and psychological effects of VR are an ongoing issue. Prolonged exposure to VR environments has been associated with mental health implications, such as increased anxiety, disorientation, and even addiction. While VR provides unique opportunities for entertainment and learning, there is growing concern about the negative effects it may have on mental well-being, particularly in children and adolescents (Weinstein, 2018).
In addition to these technical and psychological challenges, VR is still a relatively niche market, and there is a lack of widespread awareness about its applications and benefits. Many people are still unfamiliar with how VR works and its potential to transform industries such as education, healthcare, and business. The slow adoption is partly due to the perceived complexity and novelty of the technology, which makes it difficult for non-experts to fully engage with it (Dörner et al., 2016).

1.10 Definition of Terms
Virtual Reality (VR):
Virtual Reality refers to a computer-generated environment that simulates a real or imaginary world in which users can interact through sensory experiences, typically visual, auditory, and sometimes tactile. The experience is immersive, making the user feel as if they are physically present in the simulated world. VR is commonly used in gaming, education, healthcare, and training simulations (Jerald, 2015).
Augmented Reality (AR):
Augmented Reality involves overlaying digital content on the real world, enhancing the user's perception of their environment. Unlike VR, which immerses users in a completely virtual space, AR integrates virtual elements into the physical world, often through devices like smartphones or AR glasses (Azuma, 2001).
Immersion:
Immersion in the context of VR refers to the feeling of being fully surrounded and engaged by a virtual environment. It is achieved through sensory inputs like visual displays (e.g., VR headsets), sound effects, and in some cases, haptic feedback devices that simulate touch (Lombard & Ditton, 1997).
Head-Mounted Display (HMD):
An HMD is a key device in VR technology. It is a wearable unit that covers the user's eyes and sometimes ears, providing them with visual and auditory input that immerses them in a virtual environment. This technology is fundamental in creating the sensation of presence in VR experiences (Wilson, 2017).
Presence:
Presence is the psychological state where a person feels "present" in a virtual environment. In virtual reality, the term refers to the illusion of being physically present in a virtual world, despite knowing that the experience is computer-generated (Slater, 2009).
Simulation:
In virtual reality, simulation refers to the imitation of real-world activities or environments in a digital space. These simulations can range from simple activities like walking through a virtual room to complex scenarios such as flight training or surgery practice (Freina & Ott, 2015).
