Being Connected Every-time and Everywhere

Ubiquitous Computing

Alignment to Moore's law, computing power / memory are getting smaller and cheaper year by year. Technology has creeped into everyone's life... gone were the days where only tech savvy individuals whom are masters of computer program could interact with computing devices via a keyboard and programming platform. These days, devices can be commanded via voice...and now they understand human language! 
SIRI was first launched in Feb 2010. it understands human speech, different languages... even can be trained to understand accents!
Users no longer need to know the complexity of search engines, location-based tracking, "Siri, I want to eat pizza for dinner, tell me where are the pizza outlets around me"
Instantaneously, SIRI acknowledge / understands the request, she retrieves your current location via GP, crawls through the web and locate pizza restaurant within 3km radius around you and displays it onto your mobile phone ! AMAZING !

SIRI removes the cognitive load of going thru different internet webpages, geographical analysis. She can even provide recommendations if you let her check the reviews on Yelp. It is so easy to use, as long as you have a voice, you would be able to engage SIRI services! 

Other than performing searches on the internet, SIRI can relate to your applications as she retrieves your chat history, photo history, play your playlist at your request.

SIRI now sits snugly within inch-scale devices like our mobile phones, they can perform computing and communications. I am a believer of the law of equilibrium, technology serves as a double edge sword. It is like everybody has a personal assistant / secretary if you think positive, OR every of your whims and fancies, decisions and actions are always being tracked. 



Wearing Your Devices
Other than talking to a digital device, taking a step further, how about wearing it and bringing it everywhere. My childhood days have this wearable device, Saiyan Tracker... it was a glimpse into the future where actual world is augmented by assessment of individual combat power values and also ability to provide geo-spatial details.






So when the google glasses was announced, i thought my childhood's coming true!


I guess it failed to gain traction with its initial high prices, lack of use cases / applications. It seemed to be too ahead of their time.

But what I loved about it was that it was a great interface to augment the interaction of a user with his/her environment. The glasses does not mask / cover the existing environment, which means users can still observe or relate to whats happening in real time. The information that is "pasted" into user's vision (or even voice in the future or vibration for notification) serves as additional medium that the device can interact with the wearer.  

Maybe the design / fashion wasn't the immediate consideration when developing the device.... which could be a factor to the low adoption rate too. But what I really thought was that the applications and users are still in the infancy stage for such wearables. I do believe as technology continues the climb, we will find further uses or even compliment wearable with other equipment (mobile phones, electronic appliances) as the world becomes more connected... Watch out for 5G is coming to connect us!

But I heard that Apple is coming up with a similar product ! Hopefully they can do better !

Usability Study on YouTube~

 Like carpark coupons, MediaCorp artists like Zoe Tay, Lee Nan Xing which were known as <UNBEATABLES> have been replaced by You-tubers and YouTube Channels.

My two kids (aged 8 and 10) are fans of Tan Jian Hao, Sis vs Bro (Karina and Ronald Calor), PinkFong (with their famous BabyShark). I have been converted….literally when my YouTube playlist recommendations are plastered with my kids’ preferences. YouTube must be really easy to use, even toddlers in Food courts and MRT also know how to use them… that spurred my interest to learn more on this video streaming platform.

When I found this paper that was done up in 2017, it looked at ease of use, usefulness and satisfaction of users with combination of recording videos, mouse and keyboard heat map. There were observed difficulties in using it at the first moment but users would be able to get the hang of it rather easily. It shows how usable YouTube website especially in the learnability and memorability aspects.

While This paper aims on addressing gaps in the usability of YouTube website especially for the main features such as login, upload, share, subscribe and change language, content location, and restricted mode, it was stated that all ten participants were males and 15 years old.  I would think the consideration of availability of participants and cost constraints did place a limitation on the variety on the participants’ sample group. Students with zero budget and coupled with a tight timeline, they could only rely on their course-mates and friends.


The 3 hypotheses looked at:

A.      How easy the interface was (lesser clicks means easier to navigate)

B.      How satisfied participants were with the interface

C.      How well the process flow was designed (the better, the faster they can complete the tasks)

 

What actually caught me was the suggestions:

1.       Including the sign-up button on the actual page back in 2017 and YouTube actually now has it (circled in red in screenshot below).  


2.       Allowing users to sign-up / in using other than Google Account. This functionality also been included in YouTube

 It just mean that YouTube definitely have a more comprehensive Usability Testing to ensure that even the platform keeps evolving to be one of the most enjoyed and easy to use platform.

In conclusion, based on the usability study, YouTube is well organized, clean, very useful, and easy to use, respondents were able to learn and memorize the task in short time which mean the YouTube websites is highly usable.

Evaluation of "Gamified" Systems~

The paper highlights the raising trend / demand of ICT jobs but it seems that ICT job was deem as not exciting or even boring...before even ...
