ADM-Red Team – Progress Update

After the iLight site visit, we have decided that we would like to put our installation under the bridge near the Esplanade area.

The consideration why we choose this location:

  1. Sheltered, will not interfere with the circuitry that we are going to install.
  2. This is a less crowded place, will be able to show interaction more noticeable.

As for the project itself, we have discussed with the IEM side and ask about feasibility with IEM Prof that we are going to make hanging flickering lights to make starry night effect, with constellations that are going to be brighter than the rest of the stars. Each star will be encased in a hemisphere casing that will diffuse the LED lights. Stars for constellation will also be made more prominent than the rest

Interaction-wise,  it will be similar to the original idea, where there will be tubes representing the city towers with bright lights and as people approach it, the city lights will get dimmer and show the starry night sky.


Good example of Interaction Design

I think a good example for thoughtfully designed user experience for a digital user interface is Medium. Its ultimate goal is to let the user write a post, and Medium has successfully achieved this goal by creating a clean UI that only focuses on blog posts/articles that people have written, also using easy to read font type which eventually makes the user be more confident in what they are writing. The browsing and searching for the article is just a secondary feature. Sharing to social media is also very easy with just a click of a button.

Clean cut look with big fonts that does not restrain eyes

Another good example for good user experience on the digital platform is Amazon. Sure, UI wise Amazon might look cluttered. However, if you are trying to find the product that you are looking for, from the homepage itself there are a lot of interactions that are very intuitive. For example, once we hover onto a category, the menu expands to show us the sub-categories, lead us deeper into the catalogue so that we can find the thing we need within a few clicks. This makes shopping very easy and very fast, thus encouraging people to return to Amazon everytime they need something.

Unplug for a day


Today, I use my mobile devices aka phone all day, as per usual.


I turned off the alarm from my phone when I woke up and the first thing I did was to check if there are any important messages on Whatsapp, any update on group projects (since I was away from Singapore during recess week), checking if there are any assignments from the makeup class that I had missed.. Next thing I know, I was browsing Facebook and Instagram, my 2 favourite social media platforms, to catch up with the happenings, what are my friends doing and to watch funny videos too.

After taking a bath and eating breakfast, I helped my mum doing house chores, nothing interesting there…


After finish with everything, I joined my mum to watch TV. By then, it was already lunchtime so we went outside to buy us some lunch. Since we could walk to the restaurant, there was no need for us to use an app to look for restaurants or perhaps order a cab to get there. But every once in a while, I still browsed social media everytime I get bored (for example, when we were waiting for our food). I noticed my mum also check messages while we’re waiting. She also took pictures of me to show to dad, we happened to be in a relatively cute little cafe.

After lunch, we went home. I watched a drama in my room using my tablet until I fell asleep for a nap.


After my nap, I took a bath again (yes I take a bath twice a day) and then I did my schoolwork using my laptop. I also listened to music using Spotify on my phone. For dinner, my dad took us out to a  restaurant and as per usual, I browsed social media. I went home, continue doing my assignment and went to bed.


Time to unplug.


I purposely opened my drapes so that I would be woken up by the sunlight, and I did. So instead of checking for messages, I went straight to the bathroom to take a bath and went down for breakfast. After helping my mum with house chores, she had the day planned for me, so she took me out shopping.


The day wasn’t so bad until I realise I cannot Instagram story my food for my friends. I guess that was the sad thing about having to unplug. I also realised since I did not bring my phone with me, I treasure the quality time I had with my mum more, I initiated conversation more now that I did not have anything to distract me.

It was a good thing that I did this experiment when I went home so that I did not need to worry my family from being uncontactable. Also, since I was away from Singapore, I decided to really relax and enjoy myself, not to worry too much about schoolwork related messages. I was also thankful that my friends were very supportive in understanding that I was on holiday, spending more time with my family, that they were okay with me replying them even though after one day disappearing.


Normally, I use my phone to chat my mum, call people, browse the internet when I am bored, exploring funny videos on social media. Sometimes I also use my phone when I suddenly want to look up for some random facts online, about movies, celebrities or even history on Wikipedia.

I use my phone to connect with people. The fact that I stay abroad, away from my families, the presence of mobile devices and the connectivity provided by network service provider eases the communication between my family and me.

I don’t usually play games using my phone, but I realise that my mum likes to play mobile games on her phone and on her tablet. I also observe that when people use their mobile devices, they seem to be immersed in whatever they’re doing and forgot their surroundings. I notice that this is more likely to happen especially when people are concentrating on playing games or watching dramas on their phones.

Response to: Interactive Environments & Experience Design

Timothy Nohe’s presentation for his interactive touchpad synthesizer shines a new light onto how we can provide a hint for collaboration to take place within an installation.

The most important takeaway I get from Timothy Nohe’s presentation was to make the interaction as intuitive as possible. For example, the touchpad box itself acts as an affordance, giving people the idea that it is the controller for the interaction. As a result, people will be curious and explore what else can they do with the machine.

Tim noted that humans are social beings. His installation can make people collaborate with each other, by providing more than one machine so that people can also learn tricks from each other, making a whole new sound.


Future World by TeamLab

This is the second time I have visited Future World exhibition by TeamLab at ArtScience Museum, so I got to witness the changes they have made. During this field trip, I am glad that the place is not crowded so that I got the chance to understand the technical aspects they use to enhance the experience of art and play.

Last time, the first exhibition was a room projected with flowers instead of the Crows. In the current Crows exhibition, not only it is more immersive and thrilling, they also use spotlight to signify the best spot for viewing.

From User Experience point of view, these exhibitions are designed to make people curious and questions what would happen if they do certain actions. And thanks to our guide, Takasu, we are able to understand what kind of sensors they are using, what kind of concepts that drive TeamLab to make this exhibition. All these information are important for us to further develop our ideas on the iLight project.

iLight Festivals – Previous Installation

I understand sustainability as a form of avoidance of the depletion of natural resources, such as oil and coal. Sustainability also means trying to save wildlife as they are connected in the ecosystem to natural resources. There has been a lot of campaigns about sustainability, whether it is to save electricity, save the ocean from garbage, as well as switching to alternative energy resources. A particularly relevant point for iLight installation is the campaign about saving energy and switching to alternative resources. I find iLight is a suitable method to send these two sustainability messages as light installations attract people to come and also interactivity engage people actively which would make a stronger impression for people to bring these sustainability messages home.

I went to iLight festival this year and last year. One of the installations that particularly caught my eye is this:

This installation is called Horizontal Interference. It is basically colourful tapes wrapped around poles in Marina Bay and were shined UV light. The result is a beautiful installation that looks as if the strings are LED strips themselves. This is such a brilliant idea to showcase an art with a minimum amount of energy. The installation itself serves as a good example on how to save energy and still can create something pleasant to look at.

You Are What You Carry

I agree with Chipchase’s point that technology advancement makes us carry less, remember less to owning less. Let’s just talk about mobile phones for instance. In the 1990s, we still carried mobile phones that are so bulky, with an antenna on it. Now, our mobile phone is pocket sized and multifunctional. We do not need to carry another hard copy of maps of the place we would like to visit, we do not need to carry an address book full of contacts of important people. We carry less and as a result, remember less as well. Whenever we want to call someone, we don’t even need to type in their phone number, we just select their name and make a call. As technology progresses, people realise that they do not use all the things they own very often. As a result, the sharing economy is introduced. We are now sharing cars with strangers through sharing apps such as Uber and Grab. The presence of these apps gives us the sense of security we never had before when we simply were not allowed to climb into a vehicle with strangers. Thus, we also own less: having a car is no longer a necessity.

I like the observation of paradox in Afghanistan. With low literacy rate, sometimes technology might not be the answer to improve the level of security. Sometimes people are more trusting when they see with their own eyes. The same thing also happened in a lot of developing countries, such as Indonesia. When the government tries to automate passport application in Indonesia to tackle the problem of scalpers, people are not very responsive to the system change, thinking that there might be a suspicious new corruption technique by the government.

The Anthropology of Mobile Phones

Jan Chipchase mentioned some relevant points I have seen in my life. First, regarding the valuables that people carry: money, key and mobile phones. He also mentioned that mobile phones have actually situated at the security and even physiological needs level at Maslow’s Hierarchy of Needs; a point that I have not realised before. Looking back to 2007, I used mobile phones just to communicate with my family and my friends. There was a rising trend in using Blackberry phone in Indonesia and people were so excited to be able to communicate using Blackberry chat platform; the first social media we got to know even before Facebook. Now, not only we are using smartphones (without any more keypads necessary), our lives are also involved around apps, be it for entertainment purposes, or even to help us manage our lives better. This brings to the next point Chipchase mentioned.

The fact that human likes to forget things, we delegate tasks to other people or in this case, our phone to do our tasks. From remembering people’s contacts, setting our schedules, to even replacing our wallet as a medium for payment. E-banking has made our financial management very easy, deliberating the tedious process of queueing in a bank just to get the service. Paywaves, Apple Pay, Android Pay, Samsung Pay (and the list goes on…), make our lives easier when purchasing is just a tap away. As we are moving to a cashless society, e-money might some day replace cash but they are still debatable to this day. With more convenience, there are more responsibilities as well. People are becoming more anxious when they lose their phones because everything about them is on their phones. When our security and privacy is at stake, to what extent do people want to trade them for convenience?

The third point that Chipchase discussed is the street innovation. In 2007 when people were still using Nokia phones, there are a lot of repair services in malls and IT centres. Even when our phones’ battery needs replacement, we can go to these stores and look for a new one and voila! We can continue using our old phones. Nowadays, we are using smartphones with irreplaceable batteries which I think is one strategy from phone companies to beat the street innovation. However, we all know that somewhere in China, there are people who can revive our old iPhones. Therefore, designers also need to learn from the streets how to challenge the norm, to meet people’s needs better and make products that are more suitable for the user.


Calibrating your cultural compass – Week 2

I like the way Jan Chipchase studies people behaviour, from different cultures all over the world by observing their daily activities, especially the morning commute.  I agree that societal behaviour is best observed in the morning, as people usually follow certain daily habits. In Singapore, I observe people usually wake up early in the morning, board the MRT trains to get to their office which usually starts at 8-9AM, and just before they get to their office, they usually buy a cup of coffee, or even a breakfast set from nearby coffee shops. Students need to wake up even earlier to reach the school on time at 7.30 AM (note that some school have late days).

Among all the observation methods suggested in this chapter, my favourite is to observe McDonalds’ menu from all over the world. Back in Indonesia, we have Fried Chicken with rice, and when I moved to Singapore and realised that McDonald’s here do not offer such menu, I was surprised at first. I thought Singapore and Indonesia share the same spice palate since both are in South East Asia. It is interesting to find McDonald’s located at countries within the same region to have different menus. Malaysia’s McDonald’s sell durian McFlurry while Singapore’s does not.

Chipchase noted that in designing a product targeted to a certain group of audience, it is good to do some research on the cultural background. Get to know their needs, their habits, their schedule. Immerse in their lifestyle, so that we can customise the product according to the audience’s needs. With the combination of formal and informal data collection, this method could help us in understanding a society and therefore help us to make a better decision in designing products.


  1. In doing a cultural research, is it necessary to also observe the night life of a society, to collect observation about the security level and crime rate in the area?
  2. In a multicultural country such as Indonesia, how to make a general observation so that the product we design can benefit people from different backgrounds, both in urban and rural areas?

The Design of Everyday Things – Chapter 1 Reflection


As an engineer, I admit that when I build things, I like to think about the functionalities first before the design or how can the product serve the users’ need without causing much trouble. From this chapter, I understand that as engineers, we tend to think logically, and it is true that we assume people also think as logical as us when it is not certainly the case.

When building a product, a designer must consider several aspects:
Affordance: What is the product being used for? How does it relate to the user? How does the material (properties) support its relationship with the user?
Signifiers: Clues that makes user action on the product more intuitive (natural). These are hints to communicate the correct behaviour to the user.
Mapping: map something according to what it controls
Feedback: After an action is applied to the product, there should be a feedback for the user to notify them that the action is received by the product.
Conceptual Models: Simple instruction on how to operate the machine


Affordance vs signifiers. If a product serves as good signifiers for another product, does that mean the former has good affordance?

Does understanding the human behaviour could also help generate new product ideas?
