Spatial Computing and its impact on Education

 Imagine a classroom where all physical resources have been digitally cataloged, all the sensors and devices have been connected to the Internet of Things and the digital map of the classroom has been merged with the object map. So, when the teacher carries her laptop to class, the lights come on automatically, the teacher's chair recognizes her and moves to accommodate her. The Interactive board switches on to her last lesson. The class mike becomes operational. The students entering class after attending a sports class having a digital wristwatch comfortably move to their seating area with any obstacle on their way like bag automatically moving away and the air conditioners adjust its cooling to suit the students present body temperature. Further, any student falling or having a mishap in the classroom, an alarm is sounded and the school nurse automatically arrives for support. 

Well, is this for real? Yes, this is 'SPATIAL COMPUTING" and is the next step in the convergence of physical and digital worlds. In the Top 10 emerging technologies of 2020 shared by the World Economic Forum [https://www.weforum.org/reports/top-10-emerging-technologies-2020 ], spatial computing has a major role to play in Industry redefining itself.

Let's understand the term spatial computing. As per Techslang, Spatial computing refers to the process of using digital technology to make computers interact seamlessly in a three-dimensional world using augmented reality (AR), virtual reality (VR), and mixed reality (MR). Spatial computing uses physical space to send input and receive output from a computer.

The video from DELL EMC WORLD CUSTOMER STORY. NIKE: VISION FOR THE FUTURE OF DESIGN makes the understanding very clear. 

So let's understand this through the world of education.  For starters, it enables all school processes to become streamlined, efficient, and time-saving thereby improving the quality of work. 

In the case of learning, it offers experiential, interactive, and engaging learning interaction between students and teachers. 

Let us study through an example: The students are studying Egyptian civilization and wish to see a collection of artifacts, mummies, coffins, stones, ancient belongings, and even food types that used to be buried with the kings before death to use in the afterlife. We connect with the Egyptian Museum in Cairo as they have connected all their artifacts to spatial computing. 

The app allows multiple students and teachers to view a 3D model of a historical object from anywhere in the world and in real-time when they are using an XR [Extended Reality] headset which shifts effectively between VR and AR – ideally encompassing MR [Mixed Reality] as well. So, they created a single 3D rendering of the artifact in photorealistic form. This true-to-life replica could then be exhibited in a joint-viewing area and examined remotely by anyone, from anywhere.

The museum curator can present the digital twin of the artifact to multiple students at one time. Students seated at home can highlight, enlarge objects, examine the artifact, ask questions to the curator and also ask peer-to-peer questions. They can even walk around the artifact. 

Take another case of students conducting experiments, mixing Hydrogen and Sulphur, and seeing the production of hydrogen sulphide and being able to smell the rotten eggs odour. It allows students to experiment with the materials, measurements and note down observations and arrive at conclusions based on evidence. Similarly studying a heart in 3D. Now, would one really need a laboratory?

In Literature, it allows the stories or movie discussions to come alive and students actually witnessing the stories and discussing the characters in real-time with other educators or peers across the world. 

In Geography, if you are studying Sahara Desert, you are actually there feeling the heat, the smell of the dessert, the texture of the sand. You actually watch the gerbil, jerboa, Cape hare, desert hedgehog, Barbary Sheep, scimitar horned oryx moving about in real time from the comfort of your own homes or classrooms anchoring your body into the experience. Similarly getting an undersea experience. Isn't that exciting? If you are wondering when this is going to happen then do note the XR glasses are still in the R & D phase but very much around the corner. 

Education then has taken up a complete transformation and physical spaces have merged with the digital making learning truly immersive. Much obviously, the teacher training will be upmost on the list ensuring that every teacher has adapted themselves to the technology and given the recent COVID 19 scenario and the manner the teachers rose to the occasion, that will be the least concern. 

Further, curriculum developers, textbooks, research book publications, software companies will have to gear up to provide the students with the spatial experience. With all the recent advances, the future does seem optimistic with the world compressed by a single click.

Top 10 Emerging Technologies of 2020 and its impact on education

This week, a colleague, Arijit Ghosh shared the special report, ' Top 10 emerging Technologies of 2020'  https://www.weforum.org/reports/top-10-emerging-technologies-2020 of the World Economic Forum and since then I have been reading it and trying to understand how it will impact education at the school level. In any school, the latter half of any academic year is invested in planning for the next year and most teams are continuously striving to update the curriculum so that STEM in school is connected to Industry and students are prepared with skillsets for the future. 

Of the 10 technology, today I wish to touch upon 'Sun-powered Chemistry' for the very reason that UN SDG's are taught in most schools and all curriculums are designed around it. As per IEA [International Energy Agency], article dated 11 February 2020, Global energy-related CO2 emissions flattened in 2019 at around 33 gigatonnes (Gt), following two years of increases.  

As per WEF, at present, we rely on fossil fuels but a new approach holds the promise of reducing the sector's emissions by using sunlight to convert waste carbon dioxide into useful chemicals. This is a step towards creating 'solar' refineries to produce useful compounds from the waste gas, which could turn everything from medicines, detergents to fertilizers and textiles. In this process, wasted carbon dioxide becomes your raw material, and the sunlight is the source of energy needed for production. 

Let's study its impact on education.  In school, when we teach Chemistry, we speak of single [Ex: Hydrogen] and multiple covalent bonds [Ex: Oxygen] between molecules. The multiple bonds are difficult to break and the bond energy present in carbon dioxide (O=C=O) is 187 kcal, whereas when this bond is found as part of a larger molecule, the value is closer to 170 kcal. Huge energy is required to break them and now photocatalysts which are typically semiconductors requiring high energy ultraviolet light (5% of sunlight) will be used.  Once the bond is split, the raw materials will be used in the manufacture of plywood, cabinetry, flooring, and disinfectants. The Chemistry chapters on organic chemistry, bonds, and energy will need to be revisited.

So if CO2  gets used up then let's analyze the impact on the environment. Less carbon dioxide will lead to lower levels of global warming which in turn lowers the rate of Climate Change which in turn helps in the conservation of nature. So, the benefits are immense and the future holds positive for the generations to come. Lessons on pollution, types of pollution, and the conservation of the environment will need to be revisited. 

The students will be addressed on how solar chemical research is progressing as many start-ups are working on this different approach to convert carbon dioxide into useful products and this offers a range of careers for them in the near future. So, virtual/physical visits could be planned, talks with experts could be arranged, STEM career events or Coffee talks could be held to orient students on the new technology awaiting them in recent times. 

Next week, we will try to understand how 'Spatial Computing' will impact education. 

Do share your constructive feedback and how this blog could be updated for better understanding.
