Minecraft, GTA5, Mario Games and League of Legends. I’m sure that you must have heard of at least one of them, or you may even play all of them. I did, we all did. Good afternoon, everyone. I am Simon, together with me are Grace and Regina. We all love playing games and we want to explore more about physics behind gaming. In particular, gaming consoles. So today we would like to walk you through the development of gaming consoles in the past 12 years. From Xbox Kinect to PlayStation VR, following with Nintendo Switch. Without further ado, let’s start with our first gaming consoles: Xbox Kinect. STOP! Moving on to Nintendo Switch, a breakthrough in gaming. It transforms from home console to handheld, by using a pair of controllers called Joy-Con. These Joy-Con are pretty impressive, even when I turn them just a little bit, they can sense what I’m doing. What’s the physics behind? Without further ado, let’s discover it together. Inside each Joy-Con is a sensor designed to measure the speed and direction of rotation. So, when we talk about twisting or tilting, what we really mean is rotation. And this incredible sensor is called the gyroscope. In short, the gyroscope lets us measure rotation speed. However, rotation isn’t the only kind of motion the Joy-Con can detect. It can also sense acceleration and it’s called the accelerometer. Acceleration in short is about the “rate of change in velocity per unit of time”. To make it simple, the Joy-Con can detect when it was moved. The truth is, sensing movement isn’t all it can do. The accelerometer has the secret ability to help you guess which way is down. If you know which way is down, that means a game might be able to guess how the Joy-Con was tilted. You may wonder, how it works? Let’s see. The eyes will move, and the point is to pay attention to this arrow. You’ll note that it’s always pointing down even if I tilt the Joy-Con. The angle between the Joy-Con and down means you can estimate how far it’s been tilted! Strictly speaking, the gyroscope measures angular velocity, that’s the rate at which an object rotates over a certain period. For example, if you multiply the angular velocity by the length of time, you can estimate how far you’ve rotated. But that only gives the angle relative to the initial position. If you want to try to figure out the absolute measurement of tilt, you’ll need to get some ideas of that initial angle as well. That’s where the accelerometer comes in. The accelerator information can be used to guess gravity, which is an absolute reference point. You can use that as a baseline to understand the gyroscope’s relative measurements. To recap, the accelerometer could help us estimate its angle when it’s standing still. And the gyroscope is great at measuring the controller’s rotation while it’s moving around. Both are useful for estimating the tilt of the Joy-Con and they need to work together to compensate. STOP! As you can see, the physics behind gaming consoles are not only limited to entertainment, but also medical application. Next time when you are playing Mario on Switch, take a look at the joy cons. They are the masterpiece of game. So, thank you so much for your time. We’re very pleased to be able to present a lot about physics behind gaming. We’re now open the floor for your questions. NEXT! So, one of the ultimate goals is to expand into the international market, right? One way to do so is to foster an ethical culture within Kitchen Best. So introducing you with our 1st recommendation, Know Better. Know Better is a framework taking international regulations into account. It aims to raise your awareness on ethical business practices and reassert corporate governance.  So you may wonder what is so special for the regulations outside Asia. For your information, the Organisation for Economic Co-operation and Development, OECD, aims to promote sustainable economic growth around the world. And they place a high value on integrity. For example, last year, it published an anti-bribery recommendation. Its member countries like the US, Germany and France have shown a positive attitude to it. So, you can see the integrity standards in non-Asian countries are very high. To tap into the international market, Kitchen Best should now refine the working principles. So what exactly is Know Better? First off, it starts from an educational workshop. Every month, you will be exposed to knowledge like honesty at work, social responsibility and business ethics. And the speakers will be coming from different organizations like ICAC, USAID and GRECO. They are the independent statutory body of maintaining ethical business practice. They often organise free educational workshops to companies. We will also invite professors from local universities to give a talk. The ultimate outcome is to let both you and your staff to Know Better. One workshop will be held each month and after every workshop, we would like you to spread the importance of upholding integrity in Kitchen Best. You will be the role model of your staff and you will be helping with the refinement of the ethical framework. Feel free to adopt what you have learnt in workshops and make the framework applicable to every foreign country.  Eventually, you will play the important role to convey a positive and ethical image of Kitchen Best. With that being attained, your company will then be one step closer to the international market. And you will possibly get promoted and help supervise the cross-border business of Kitchen Best. So what is the next step to go? NEXT! Good afternoon everyone. Do you know 90% of Hong Kong citizens own a smartphone and the average Hong Kong citizen spends at least 7 hours of their waking hours on the Internet? In fact, the figures are not surprising. You can see from our classroom, you all have at least 2 gadgets on the table. So today we are going to tell you how to get rich with your gadgets. Exciting right? So I am Simon, together with me are Aby, Alice, David, Frankie, Kelly and Will. We are Group 5 and we are going to Introduce you with our business discovery, live commerce. Live commerce combines instant purchasing of a featured product and audience participation through a chat function or reaction buttons. I could see the question marks on your face. It makes sense, let me show a short clip. The girl on the screen is the host, she is in her home, selling the product to the audience. The video quality isn’t good cuz it was taken with her phone. But anyway, if you would like to buy the product, you can just click the order button, and done. The host can earn $$ and you can get the product. After watching this clip, I guess you have a brief idea of what is a live commerce? Do you want to join it now? Don’t tell me now, give us 20 minutes and allow us to spend some time to share more about it. Maybe you will change your thought later! STOP! To recap, live commerce has just reached 400 billion sales in China this year, and the figures are still increasing. With many merchants tapping into this market, are you wondering how a business can stand out from the crowd? In the last of 4Ps of marketing, we have promotion. We will be focusing on how a business can increase its conversion rate with promotion. Before introducing the promotion strategy, I would like to walk you through on how to create web traffic. Currently, we are living in the digital age, where big data plays a vital role in our life. Live commerce is no exception. It takes all sorts of quantitative figures to measure the performance of a business. So what kind of KPIs will be taken into consideration? Introducing you with ARA: activity, retention, and attraction. Let’s start with activity. This is the interface for a live on TikTok. As you can see, there are chat functions and reaction buttons. They represent the audience engagement level in the live. The more reactions you receive, the more engaged your audience is. Secondly, we have retention. A well-done live commerce should be able to keep the audience staying in your live. For instance, if you’re getting audience retention above 70% in the first 30 seconds, then you’ve got your hook on the live and you’re doing a good job. It also applies to real-time presentation, Btw, thanks for staying awake. Lastly, we have attraction. As mentioned, it’s a unique feature of live commerce. The more gifts and rewards received from the audience, the more likeable your life is. So if you have a good ARA, the platform metric will pull in more traffic to your live, and possibly result in a higher conversion rate. Arriving at this point, you may wonder how to achieve a high ARA. It’s the key to get rich! So listen carefully! Imagine if you were a buyer, searching for some goods, and you could see two different people selling different products. Which one will you click into? Someone would choose a fancy product, but I also believe that some of you would pick the celebrity. Unlike traditional business, the core part is no longer the product only, it is also about having fun, and let customers to fully immerse themselves into your live. So, it is about integrating customer experience (CX) into your promotion. For instance, it is very common to see KOL or KOC hosting a live on TikTok (can adjust to the example mentioned before). They have experience in content creation and generally have a solid fan base. By hiring them as your business partners, your business can surely kick off the ARA with audience. Another alternative would be hiring a dedicated in-house team to plan and develop content for livestreams, including storylines, scripts and hosts.
