What is augmented reality?

The concept of augmented reality has been present for some time, as there have been inquiries regarding the non-physical body and the extent of interaction with the virtual realm. In response, various devices and interfaces have been created to allow for the visualization of the digital world and its projection onto the physical world without direct physical interaction. It is imperative to note that while it is not possible to affect the digital realm or leave the physical world through physical means, all interaction must be conducted through the utilization of these specialized devices.

Over the years, significant progress has been made in the field of augmented reality technology. As such, it is now possible for individuals to access and utilize various devices or interfaces that allow for the visualization of the digital world and its projection onto the physical world. It is important to note, however, that this interaction is limited to the use of such devices and does not permit direct physical interaction with the digital realm. Despite this, the democratization of augmented reality through the creation of filters and lenses by major companies has allowed for a quantum leap in the accessibility and utilization of this technology.

The creation of filters within this framework enables the modification of facial masks through the use of facial recognition and a collection of masks that can be accessed at the specified link. By utilizing the provided mask and utilizing an editing program such as Canva, Photoshop, or any other suitable software to incorporate objects or make changes, the resulting image with a transparent background in the form of a .png file can then be imported into Spark to obtain results similar to those depicted in the aforementioned photo.

Similar results can be obtained through the utilization of a series of nodes, in which the concept of importing 3D objects into the space with a collection of textures is employed to enhance realism and depth. In addition to this, the incorporation of mask changes produces a dynamic and interactive filter. These features can be tested at the provided link, which offer a 360 space to take photographs in various locations.

My nodes in SparkAR

Exporting 3D models into SparkAR

At this juncture, we can observe how the nodes work has been substantially impacted by the introduction of the touch screen. Subsequently, my work is rooted in an event concerning the death of an individual due to undue police force. My goal is to illustrate what transpired afterwards and to showcase the reactions of the public in the face of the police authority and the destruction of numerous Emergency Attention Centers (CAI). To this end, I used Spark AR to recreate a destroyed CAI in SketchUp, textured and processed it in Blender, and exported the meshes using an extension. Thus, the object was successfully imported without being rejected.

Once the textures were finalized, the object needed to be manipulated to appear burned and ruined. Subsequently, a 3D object preset from SparkAR was employed, enabling the object to be placed on any plane and give the impression of being tangible in the real world. A spacious area is necessary for an optimal effect. However, the camera must remain static, as any movement will cause the object to also move. The target tracker could be a better choice, as it allows the object to stay in place through recognition of a guide. Nevertheless, this option has its own restrictions.
