TASK 1

Exercises

For Task 1 of Experiential Design, we were given series of exercises that explore the current, popular

trend in the market to give us a better understanding of the technologies and the knowledge in creating content for those technologies. 

The requirements are the following:

• To complete all exercises to demonstrate understanding the development platform fundamentals.

Exercise 1 + Activity 1

Exercise 1

In our first exercise, we had to look a set of images and identify what type of XR experience it was by determining whether it was AR or MR.

Fig 1.0 1st Image

Fig 1.1 2nd Image

Fig 1.2 3rd Image

Fig 1.3 4th Image

Fig 1.4 5th Image

I had identified image 1, 3, & 5 as AR experiences and image 2 & 4 as MR experiences. The reason 1, 3, & 5 are AR experiences is because although it is overlaying digital content, such as images and text onto the users view of the real environment- it is only interactable through the use of a display screen, such as a tablet as depicted by the three images. The digital content in AR doesn’t interact with the real world and remains separated from it, it is contained within the device's display screen unlike MR which I have identified in 2 & 4. 2 & 4 are MR experiences as it combines elements of virtual/digital components with the physical world in a way that enables the virtual/digital components to interact with the real environment. In MR, the user is able to manipulate and interact with the content as if it’s part of their surroundings.

Activity 1

For this activity, we had to launch google.com on our phone browser, search for dinosaur, dog, cat, or tiger, then view it in 3D and in AR where we can observe a life size model.

For Exercise 2 we are to imagine a scenario in either of the three places. 

• Kitchen
• Shopping Mall
• Gym

What would the AR experience be and what extended visualization can be useful? What do you want the user to feel?

For this exercise I thought of a Recipe Guidance AR experience where users could see step-by-step visual instructions overlaid on their workspace through their display screen, guiding them through each stage of a recipe. This could include animated demonstrations of techniques like chopping, stirring, or baking.

I made a simple mock-up visual example of how this could work with a simple guide for egg fried rice, detailing 3 steps with a little mini gif of stir-frying wok technique.

In terms of how users should feel, the AR experience should aim to make them feel alleviated, confident, informed, and inspired. Overall they should feel more confident in their cooking abilities with the guidance provided, and satisfied with the efficiency and effectiveness of the AR tools at their disposal. Ultimately, the goal is to enhance the user's overall cooking experience and make it more enjoyable and rewarding.

For this exercise, it was a group activity where we were divided into 4 groups. We had to make a journey map of a chosen destination and describe the experience and journey, integrating elements of AR to solve shortcomings of the journey wherever it was possible. Listing out the gain points, pain points, and solutions of each stage of the journey. 

For our groups (Group 2) journey map, we decided to do a journey map of the Universal Studio of Singapore Theme Park. To carry out this exercise we collaborated on miro. The journey map can be viewed in the below image or through this link

Exercise 2

In this exercise, we created a scannable and trackable AR experience using an image as the target in Unity with the Vuforia Engine. We enhanced the experience by adding an animated cube that could be controlled with functional buttons to the AR interface, allowing users to move or rotate the virtual object.

First, we needed to prepare an image for the target. In order to create the target, we had to upload the image to the Vuforia website where we could download the database for it from. Below is the image we used. 

Fig 1.7 Astronaut Image Target

The Vuforia website has an function to it that allows you to upload and check your images/files in the database to see if the image can be scanned properly in Unity, it runs on a star rating, where 5 indicates that there are no problems with the image, 3 has minimal problems but is still tricky, and the rest being bad for scanning. 

Fig 1.8 Adding Target in Vuforia + DL Database

We learned that in order to fit the criteria, the image needs to be:

• Rich in detail (lots of features that stand out)
• Well contrasted (bright and dark areas)
• No repetitive patterns
• Format must be 8 or 24bit PNG/JPG(RGB/Greyscale) and less than 2MB

Then, starting out in Unity, I downloaded and imported the converted image into the program as an image target. I also added a 3D object (cube) and set the position to sit on top of the image and added a feature that would allow me to use a webcam/phone to scan my image (ARCamera).

Fig 1.9 Adding

I could test and see that my image scanned successfully by pressing the play button at the top, and because I made the 3D object (Cube) a child of the image, it showed up as a feature of being scanned. 

Fig 2.0

Next I created the animation of the cube. To make the animation levitate up and down, I first started the recording and set the time stamp to half a second (.30), then I pulled the object up. I needed the object to go down without resetting to create a smooth animation, so I copied the first sequence and pasted it on the 1 second marker. This created a loop of the object going up and down. 

However, I noticed that the object was moving too quickly for my liking, so I adjusted it by stretching out the timeslot in the frames to 2 seconds to expand the animation time, this would slow the animation and make it move at a more relatively moderate pace.

Fig 2.1

Fig 2.2

This is where my animations were stored, I created 2 animations: Static & Animation. I made it so the first thing you see when scanning the image would be an unmoving object. Animation is the object in motion, looping. This is done by right clicking and setting the animation you want to be the 'entry'. Static was my first animation, so it was the default.

Fig 2.3

Here I created a canvas through the UI setting in hierarchy and switched to a 2D viewpoint to make it easier to edit. The canvas is needed for the set-up of image prompts/buttons. I also made my canvas fit in a 16:9 ratio and to be allocated for IOS in the Game's tab as that is the phone I use. Then, I scaled the resolution to a 1080p monitor on the right (1080 x 1920 y).

Fig 2.4

Under my canvas I created a button in the expanded UI menu. I then changed the size and text to 'Move' and linked it to the bottom of the canvas with the pivot option. After having created my button, I needed to give it functionality. On the "On Click" menu, I added a new performance and dragged the cube into the priority slot and gave it the functionality of animation with the exact name of the animation to allow it to work.

Fig 2.5

Here you can see that the button successfully worked at making the object move in the desired animation.

Fig 2.6

I then went on to create another animation for the cube with the same principle as the up and down movement. With this one, I would create a 360° rotation recording with a time-span of 1 second. I would then create another button via copy and paste of the previous button, with the functionality of rotating the object upon being clicked.

Fig 2.7

Fig 2.8 Object animation list

Because I had created 2 buttons to make the object to move, I hadn't made the option to make it stop, soI created a button that would play the animation 'Static', bringing it to the entry animation. This would give the user more control over the object and allow them to 'pause' the animation.

Exercise 3

This exercise is a continuation from the previous one. It first starts with the addition of a 3D sphere, plane and then adding the provided video to the 3D Plane.

My first test of the of the video was a success

Here I added instructions to the video 3D Plane, so that it would only play when the device is continuously scanning. I made this possible by making it so the app would not track the device, so that it would only be activated by the image.

Here I updated the buttons to suit the new project. I also added in instructions to respond to their appropriate button when pressed/clicked. I did this by adding in a videoplayer (play) and (pause) on the appropriate buttons.

I created new buttons with instructions to target the little sphere on top of the scanned image.

These buttons when clicked would Show and Hide the Object(sphere) for the viewer.

I did this by setting the buttons to activate and deactivate the 3D Sphere in the hierarchy.

Here I began to start animating the Sphere, same principle to how I animated the cube, however I extended the animation time to give it a levitation effect. This would be it's Idle Animation upon scan.

I also created an animation to stop all animations, by keeping the object stagnant.

Here I followed with the same principle that I applied to the last buttons, this time I added in animation instructions and gave each button the appropriate animations that I had made earlier.

Animate would do nothing upon entry, though you could stop the animation with "Stop Animate" and start it again from the beginning with "Animate".

REFLECTION

Reflecting on these exercises, overall it was quite tough as I had to navigate completely new softwares and techniques Id never learned before. the technicalities of everything are interesting and complex, so its difficult but rewarding in the end.
