Gesture Control Holographic Display System for Live Presentation
Project Area of Specialization Internet of ThingsProject Summary3D hologram is a classic optical illusion with a modern technical twist. It projects images to a set of semi-reflective glass pyramid to provide a 3D floating view. The technology is currently used mostly by the theatres to generate special effects or by the hobbyists to impress their friends. Some commercial projectors are developed to display products and play video games. Some people also mentioned the possible applications in education. However, most teachers have never heard about the technology.
In this proposed project, we want to apply 3D hologram to the live presentation. This innovation will transform how the teachers present a scientific object, an engineering design, or a medical anatomy. It will also change how the students present their projects, designs, and creativities.
Project ObjectivesIn this project, Virtual Reality (VR) is a buzzword for technology today. However, using true VR technology in a classroom to enhance the teaching result is still at its primitive stage. There are some large dedicated devices such as CAVE (like the one used in the South Jersey Technology Park). However, they are generally large and expensive, need a large and dedicated space that is always far from the general-purpose classrooms, and need to have dedicated technicians to maintain and operate it.
Project Implementation MethodRaspberry pi: Its a mini processor and very important device of this project;
Raspberry pi camera: To capture the gesture of human and the operate the display from forward to backward and to the volume up and down.
Solid Works Design: To make Acrylic design on software to overcome the physical flows before go for hardware.
Implementation of Hardware Design: To apply solid work design on hardware, acrylic frame will be robust and made up of wooden frame
Assembly: Fix all components, sensors and miscellaneous equipment on wooden frame.
Field Testing: After testing we will be finalizing the hardware with proper presentations and with best accurate working.
Report Writing: After performing all above task in given time we will be writing report in which we will describe each and every working component in best understanding formats.
Benefits of the ProjectIn order to display the pseudo 3D image, the input video needs to be manipulated first. The source of the video can be generated by CAD software such as SolidWorks, which is available to all students via the site license. It can also be obtained by videotaping the target simultaneously from four directions. The video streams will be rotated and combined by a video processing software, which is also readily available via Cloud. When the output video is displayed on the 3D hologram display, people will be able to view the displayed object from all 4 directions in the acrylic frame.
Required Academic Technology support: The required academic technology support for this project is minimal. The software (SolidWorks and Adobe Element Premier ) can be accessed from all university computers and from home via the Rowan Cloud. The projector itself is an off-theshelf commercial product. It is plug-and-play when it is connected with an iPad. Although we need to use a computer to record or generate video clips, we can just transfer and play the final video from the connected iPad.
Technical Details of Final DeliverablePlans for evaluation: The project will be evaluated using traditional academic assessment techniques in order to demonstrate evidence of student learning. Students will reflect on their student evaluations and reports on how the projector impacted their presentation skills and learning effectiveness. I will also develop feedback forms to the students and other audiences of the presentation and seek their inputs on the effectiveness of using the technology. At the end, when there are enough teaching materials being converted, I will run a comparative demonstration of same teaching material, one using the regular PowerPoint presentation, another using the 3D hologram presentation. I will ask the students to evaluate the two presentations and compare the results.
Sustaining the Innovation: The innovation will be naturally sustainable due to its visibility and usability in presentations and demonstrations. To further sustain it, I will continuously promote the use of the projector through the Junior/Senior Engineering University. I will be continuously running Junior/Senior Engineering University projects to produce more videos for various courses.
