Rapid proliferation of technology during the last two decades has resulted in major changes in the nature of work. Further, the networking and automation of processes in the era of Industry 4.0 have necessitated the deployment of machines to perform routine and repetitive tasks which were earlier being handled by humans. Process automation and computerization have not only resulted in the loss of various jobs, but have also created new jobs which are technology-oriented and require relevant skills. This change in the job scenario has placed a great stress on the engineering students at undergraduate level to learn new skills in order to ensure their employability. Apart from learning contemporary technologies, the students need to possess non-cognitive skills, which will help them to deliver the demands posed by the current job challenges. The paper studies the impact of learning one such technology – Virtual Reality, on enhancing the employability of undergraduate engineering students in India. A model is proposed in the study and is substantiated through analysis of primary data collected from undergraduate engineering students in India.

Keywords:Virtual Reality, Employability, Industry 4.0, Contemporary Technologies,  Learning



India’s aspiration of becoming a 5-Trillion-Dollar economy by the year 2025 is mainly fuelled by three advantages which it enjoys over other countries – Technology, Talent and Demographic Dividend [1]. Industry 4.0 has ensured rapid proliferation of modern technology across sectors. Apart from creation of new jobs, it has also resulted in changing the content of the existing jobs. These changes have necessitated the acquisition of new talent (technical skills) by the current generation workers, for staying relevant. Apart from the above two factors, India’s biggest strength emerges from its demographic dividend, as it has the largest number of youth in the world i.e. nearly 600 million Indians are below the age of 25. If these youth are imparted requisite technical skills, they would stand a great chance for gainful employment in both – the global and the local job markets. Nearly 1.5 million engineers graduate from about 3300 institutions every year in India. However, the placement rate is far too low, with less than 6% of them finding jobsin their respective domain areas, due to their lacking knowledge of the requisite technical skills[2][3]. This reflects poorly on their employability skills and raises questions on the quality of education being imparted in engineering colleges. The concern became more serious when the stakeholders reported that nearly 94% of the Indian engineers are not employable, due to the skills gaps between the Industry requirements and those possessed by fresh engineers [4][5]. However, the regulatory body, All India Council for Technical Education (AICTE) has realized the problem and addressed it in a holistic manner, by closing down substandard engineering colleges, training of teachers in modern technologies and inclusion of these technologies in the engineering course curriculum etc.


Need for the Study: The change in the nature of jobs resulting from the rapid proliferation of modern technologies has caused a crisis wherein technical jobs are lying vacant, but still a large proportion of the youth remain unemployed as they do not possess the requisite job skills. This issue was flagged by the industry nearly a decade ago [6] and reiterated through various studies [7][8]. Thereafter, AICTE recommended that imparting knowledge of modern technologies to engineering graduates would equip them with the requisite skills and enable them to be employable in the era of Industry 4.0. Accordingly, 9 technologies were identified by AICTE, one among them being Virtual Reality (VR) [9]. In this paper, the researchers have used VR as an independent variable and measured its impact on employability. 




Employability of engineers is a measure of their ability to gain employment [10] and retain it as well. In this research, the definition used for employability is based on the skill set model. Employability can also be described as “the possession of certain skills required for the job”. A study on fresh graduate engineers in India undertaken by World Bank [11] had identified the employability skills required by engineers based on past studies [12][13] as well as the graduate learning outcomes laid down by the National Board of Accreditation (NBA). A total of 26 skills were identified and further grouped into three – Core Employability Skills, Professional Skills and Communication Skills.

  • The CoreEmployability Skills mainly represent the personal characteristics like – Integrity, Reliability, Teamwork, Willingness to learn etc. These characteristics are generic in nature and apply to all kinds of jobs.
  • The Professional Skills, also referred to as technical skills denote engineering-specific skills like Problem-Solving, Creativity, System Design, Application of Technical knowledge etc. These skills are job/sector specific and are also referred to as specific skills.
  • The Communication Skills pertain to the ability to communicate and also to proficiency in using computers. A combination of Core Skills and Communication Skills is also referred to as Soft Skills.

The above categorization of skills also conforms to Bloom’s Taxonomy [14] which classifies learning into the following three domains:

  • Cognitive Skills, which concern the development of knowledge and intellectual skills.
  • Affective Skills deal with feelings, emotions, values attitudes, motivations and enthusiasm.
  • Psychomotor Skills pertain to coordination, movements and motor skills.

Professional skills correspond to the Cognitive domain and the Core skills pertain to the affective domain. But the Communication skills are not restricted to any single domain in Bloom’s taxonomy. The study also refers to Bloom’s revised taxonomy and further divides the cognitive skills into two groups – Higher and Lower Order Thinking Skills:

  • Higher Order Thinking Skills include the three uppermost cognitive skills i.e. Creating, Evaluating and Analyzing.
  • Lower Order Thinking Skills include three lowest-level cognitive skills i.e. Understand, Apply and Remember.

Virtual Reality is a digital technology, which enables the user to visualize a virtual environment through 3-Dimensional graphics and also lets him interact with this virtual world. Accordingly, this virtual environment responds to the user’s actions and gives him a feel of being in a real environment with visual and sound effects. The user’s feel can be further enhanced through added dimensions of smell and taste [15]. The technology is known by various names –cyberspace, artificial reality, synthetic environment, synthetic environment, simulator technology or virtual worlds [16].


The thought process towards Virtual Reality (VR) was first triggered when Morton Heilig designed and created a non-interactive multisensory simulator - Sensorama in 1962 [17], using a pre-recorded colour film with binaural stereophonic audio, further enhanced by scent, wind and vibration effects. The actual idea of VR was proposed by Ivan Sutherland in 1965, which included force feedback, interactive graphics, sound, smell and taste [18]. Thereafter, Ivan went further to design the first VR hardware – the Head Mounted Display (HMD), which had an adaptive stereo vision capable of tracking head movements including position and orientation [19]. This was followed by a series of inventions including GROPE – a force-feedback based VR system in 1991, an Artificial Reality system in 1975, an advanced flight simulator in 1982 and the DataGlove and Eyephone, VR devices for commercial use in 1985 [15].


Essentially, a VR system uses a computer to create a perception of an imaginary environment through an interface between humans and computers. Hence, a human can manipulate the environment in real time through his hand-gestures which are tracked by his glove; accordingly, the user witnesses a corresponding variation in the 3D image generated in his HMD. Therefore, the key dimensions of VR are threefold – Interaction, Autonomy and Presence, i.e. the user experiences his presence in an autonomous environment and is able to interact with it too [20].


Job opportunities in VR: Engineers having knowledge in VR can find job opportunities in the field of entertainment, gaming, developing simulators for simulating a hazardous job environment and for training of doctors, astronauts and soldiers [15].


Major Components: A VR System creates a man-machine interface with the primary objective of letting humans interact with the computer, for visualizing a simulated 3D environment [21]. The system has two main sub-systems – Hardware and Software. The hardware includes displays, sensors, input devices and tracking systems. The software components include the modeling module, sound module, graphics module and the simulation software.


Working Principle: The 3D image of the virtual environment is presented to the user on the Head mounted display (HMD) or any other display device (output). He in turn interacts with the environment through gestures like eye movements, hand movements, tilting or turning of the head etc. These are considered as stimulus to the computer. His movements are captured through various tracking sensors (inputs) and are sent back to the computer (processor), thereby altering the environment according to the stimuli received from the user. All these changes have to take place on a real time basis, without any perceivable delay, so that the system appears seamless to the user. The visuals combined with stereophonic audio give a realistic immersion into the virtual world, to the user. The system is further classified into three types, based on the level of immersiveness into the system – Non-immersive, Semi-immersive, and Immersive VR systems [16].


Skills required for VR Engineers: From the above insight into the technology, it is evident that the engineer who works with a VR system should have an in-depth knowledge of geometry (for constructing virtual spaces), good knowledge of virtual hardware and software systems, as well as be able to integrate the various sub-systems including man-machine interface. He should also be able to develop full-fledged VR systems to suit the demands of the user. His skill in these areas will help him design a good VR system and also to work proficiently with the system and thereby satisfy the user’s requirements effectively. The above parameters were kept in mind while carrying out our current study.




Objective of the study: Our overall objective is to study the impact of learning VR on enhancing employability of engineering graduates.


Model Used for the Study: For this study, we have developed a model, where we consider knowledge of VR technology as the independent variable and Employability as the dependent variable. The learning process is used as a moderating variable and the Higher Order Thinking Skills are used as the intervening variable. This relation between variables is represented as a flow chart given below.


Fig – 2: Model developed for the study



A questionnaire was used for assessing the knowledge-level of students in VR, using the following learning outcomes specified by AICTE in their model curriculum [23]:-

  • Understanding of Geometric Modeling (VR1)
  • Proficiency level in Virtual Hardware and Software (VR2)
  • Ability to develop Virtual Reality Applications (VR3)

The self-perception of the students regarding the above three technical attributes was measured using a 5-point Likert’s Scale.


Mapping of Variables: Our current work is based on the World Bank study referred to in Section II above [11]. We have mapped the technology (VR) learning outcomes (independent variables VR1, VR2 and VR3) to the corresponding employability skills (dependent variables) based on the skills required for acquisition of the corresponding outcome and further classified it into higher/ lower order thinking skills, at table–1.

From the above table, it emerges that- variables VR1 and VR2 contribute towards Lower Order Thinking Skills whereas VR3 contributes towards Higher Order Skills.


Hypotheses: Our overall objective was further sub-divided and translated into the following three alternate hypotheses for the study: -

H₁: Knowledge of VR contributes positively towards enhancing employability

H₂: Knowledge of VR contributes positively towards developing Higher Order Thinking Skills

H₃: Students’ technical proficiency meets the skill levels expected by the employers

Sample Design: The study is exploratory in nature. For the purpose of this research, samples were collected by administering a questionnaire to the students of engineering colleges who were pursuing their graduation in their respective disciplines, across India. Data was collected from colleges located in Urban, Rural as well as Semi-Urban areas. Random Stratified Sampling technique was adopted for collection of samples. A total of 412 valid responses were received. 


Demographics: The samples were well distributed across various demographic factors i.e. gender, year of study, stream of study and the age of the respondents. The data collected contained 50.72% men and 49.28% women.

The data collected was analyzed using the SPSS software. In order to ascertain the internal consistency of each of the variables used for the study, a reliability test was carried out. It was found that all the three variables were meeting the required criterion, with an Alpha (α) value of 0.703. Hence all the variables were retained, having been declared acceptable.

Statistical Testing of Hypothesis

As all the three variables had cleared the Reliability Test, further analysis was carried out on them, using a one-way Analysis of Variance (ANOVA) test. The results are shown at table 3.


Table – 3: Results of ANOVA test

a. Dependent Variable: Employability

b. Predictors: (Constant), vr3, vr1, vr2


Hypothesis 1: The results of the ANOVA test yielded an F-Value of 2.7 x 1016 which is far higher than the acceptable value of 2.696 at a significance level of 0.05; hence we reject H₀ and accept H₁, thereby concluding that VR technology as a whole contributes positively towards enhancing employability.


Our results are aligned with the work of [25] which quotes that “the benefits and usefulness of any study programme can be assessed through the students or graduates’ point of view. If the students are of the opinion that the programme is good, it can be converted into their ability to start a work, for performing work tasks and for future career”. Thus we can conclude that the employability of the students have a very positive impact if they possess the technical knowledge of VR. Hence, the knowledge of VR in India among engineering students results in their ability to be more employable.


To test the Hypothesis further, we have conducted a regression analysis to understand the strength of each of the three variables (VR1, VR2 and VR3) used for measuring the students’ perception on VR.



-----------------Insert table 4 here--------------------


Hypothesis 2: From the results of the statistical test, it is evident that variable VR3 has a relatively high Coefficient Beta value of 0.477, which implies that the students are comfortable in developing VR applications; thereby establishing that their capability to meet the “System Design” needs is high. This observation reflects that they have very high professional skill, which implies that the students are of the opinion that their Cognitive Skills of analyzing, evaluating & creating of Higher Order are high compared to Lower Order thinking towards the VR Technology.


Similarly, we observe from the results that the item VR2, which measures the students’ perception towards their “Study about virtual hardware and software” has a Coefficient Beta value of 0.408 which is second highest in the model summary followed byVR1, which measures the students’ “Understanding of geometric modeling” with a coefficient beta value of 0.371. The results can be interpreted as that students’ Applying, Understanding & Remembering skills of Lower Order Thinking are comparatively lesser than their Higher Order Thinking towards the VR Technology. Hence, we reject H₀ and accept H₂ (i.e. Knowledge of VR contributes positively towards developing Higher Order Thinking Skills).


Our findings are very much in correlation with the revised Bloom’s Taxonomy [24], which specifies that high professional skill indeed helps build the Higher Order Thinking of engineering students [11].


The findings also indicate that the person’s ability towards integrated thinking and action occurs on tasks that are relevant and meaningful [26]. “This happened because of the contribution from the active approaches of teaching and learning methods to develop generic attributes of the students. Generic attributes play a significant role in improving quality assurance of the students” [27]. Thereby, we can conclude that the students are not only able to get a job, but also sustain the job through the knowledge of VR, as his generic attribute has been improved, along with development of higher order thinking.  Overall, it will help the students to be more successful in their careers.


Hypothesis 3: We observe from the benchmark data [11] that employers’ expectation towards professional skills for job performance by fresh graduates has a mean score of 3.91 which is less than the overall professional skill possessed by the students, with a mean score of 3.99.

From the above results, we arrive at the interpretation that “the students’ perception about their ability to develop applications in Virtual Reality is higher than the employers’ expectation of the skill level”. Whereas the mean employer demand for the skill ( is 3.91, the mean skill possessed by the students ( is 3.99, which is higher than employers’ expectations.



From this hypothesis, we try to measure the students’ learning motivation, which is intrinsic in nature, and also the expectations of the students from learning VR technology, which is skills and experience in nature [28]. From the results, it is evident that the students perceived their learning capability level on an average of 3.99 which is nearly 4 (if rounded off). On a scale of 1 to 5, with 5 being the most positive. This result can be interpreted as – the students are 80% confident about their learned skills and experience, in VR, which is much higher than the employers’ expectation on students’ capability. Thus we reject H₀ and accept H₃.


Suggestion: From the results, it emerges that the engineering students need to focus on getting jobs related to Virtual Reality technology, like development of Simulators for training in the field of Medicine (diagnosis using dummies), Aviation (design of flight simulators) business management, infant care (with simulated babies), welding (with functional computer based tools) urban planning and entrepreneurship etc [29]. 



The results also reinforce the fact that, in addition to utilizing the institutional resources, the students have also supplemented their knowledge by learning VR through other learning pedagogies like online learning, MOOCs etc. Thus, we observe that the efforts put in by AICTE in the terms of offering SWAYAM Courses and counting them towards the regular credits for their engineering courses, has benefited the students towards developing their employability skills.


Recommendations: Students should explore job opportunities preferably in simulating various applications in the fields of Medicine, Urban Planning, Entrepreneurship, Business Management, Welding sectors so as to ensure that the skills possessed help them find befitting jobs in the fields of their interest. [29].

Conclusion: The results of the study indicate that VR contributes more to higher order thinking than to lower order thinking. This clearly highlights that the change in the educational system through reforms like teachers training, practical weightage changes and increased stress on learning by doing through internship has paid off well towards enhancing employability of the engineering students of India in the field of VR technology.
