The strength of visualisation is that it allows the human subject to visually discover patterns that are too complex or dynamic to be identified just by machine learning alone, especially in analysing the overview and details of the data and their relationship. These machine learning algorithms primarily conduct knowledge extraction and predictive analytics of probable outcomes. The multi-dimensional nature of the genomic data combined with a patients' clinical profile and treatment history requires machine learning techniques to reduce it to manageable dimensions that facilitate visual analytics 12. These are the distinct advantages over 3D visualisations on traditional 2D displays, such as desktops, laptops, and tablets. The inclusion of aural, haptic, and kinaesthetic in the visualisation can benefit the analytics because the multisensory inputs are naturally encoded within human beings, and when used correctly, it improves the perception of the information and cognitive processing 11. 11 have a useful discussion on the need for further research into immersive analytics by considering the affordance theory of the immersive technologies. Increased accessibility to these game engine platforms free the researchers from dealing with low-level graphical manipulation, which is usually very labour intensive, to concentrate on developing graphical data mapping, natural user interface, and fluid navigation. The recent and rapid growth of affordable low-cost, high performance and portable head-mounted display (HMD) like SONY PlayStation VR headset, Oculus Quest/Rift, HTC Vive, and Microsoft HoloLens, combined with the integration of feature-rich game engine platforms, such as Unity and Unreal Engine, have fostered the resurgence of immersive analytics research 9, 10, 11. Immersive analytics is an application of visual analytics that uses immersive methods to support the analysis, such as virtual reality and augmented reality visualisation 7, 8. Visual analytics enhances the user understanding of the abstract nature of data in forming pattern recognition, insight, and relationship discovery data 2, 3, 4, 5, 6. The distinctive potential of visual and immersive analytics in pattern recognition of visualisation combined with state-of-the-art data analysis and machine learning techniques is critical to turn these data into insights and knowledge usable in the real world 1. Our approach allows the clinician to interrogate the information that is familiar and meaningful to them while providing them immersive analytics capabilities to make new discoveries toward personalised medicine. This is supported with established 2D visual analytics and graphical methods in bioinformatics, such as scatter plots, descriptive statistical information, linear regression, box plot and heatmap into our visualisation. Various machine learning algorithms and visualisation methods have also been deployed in VR to enhance the data interrogation process. We utilise immersive technologies to analyse the gene expression and clinical data of a cohort of cancer patients. ![]() This paper proposes a novel immersive analytics tool for cancer patient cohorts in a virtual reality environment, virtual reality to observe oncology data models. Genomic data analysis has been used in oncology to understand better the relationship between genetic profile, cancer type, and treatment option. The immersive environment is different from a traditional 2D display used to analyse 3D data as it provides a unified environment that supports immersion in a 3D scene, gestural interaction, haptic feedback and spatial audio. The significant advancement of inexpensive and portable virtual reality (VR) and augmented reality devices has re-energised the research in the immersive analytics field.
