SM3727 Wearables - POV Reflection Group 7 Cheung Cheuk Wa Cherry (54794439) Lau Pak Yan (54802708) Siu Wing Yi Zaberina (54807520) Task 1: Video Documentation (Making Process): https://www.youtube.com/watch?v=jiaeQa8h3Sw Details of Device: Components : 7 LEDs Arduino Lilypad USB Conductive Thread Battery Cloth First, we connected the 7 LEDs’ positive end separately to different ports. Then, the negative ends were connected to the same negative port of the Arduino Lilypad USB. Afterwards, we connected the Arduino Lilypad to the computer and used the provided Arduino code to run. At last, we used a Sony a99 camera to take the long exposure photos for the final outcomes. Final Long Exposure Outcomes: Camera Used: Sony a99 Task 2: Proposed Project Description: We propose to make a POV wristband which will change its color and shape according to the loudness of the surrounding sound. It can be used in concerts for celebrities

SM3727 Reflection on Soft-Circuit Making (by Lau Pak Yan)

圖片
Demo video link: https://www.youtube.com/watch?v=Asa03k4-jAU There are several advantages and disadvantages in using soft-circuit to make things. The first advantage is that it can make the device to be more comfortable to wear. The conductive thread has a similar texture to the material of clothes. Which is soft and comfortable to touch and contact to our skin. While the traditional wires are harder to bend and have an uncomfortable plastic surface. Also, soft-circuit have lower weight than the normal circuit, which will make the device become lighter and more comfortable to wear. The second advantage is that it can provide a more natural look on clothes.   Threads of soft-circuit looks almost the same as the treads in clothes, its color and texture can be blended and merged into the clothes. Which makes the wearable device looks less mechanic and less awkward. The third advantage is that it can fit to the flexibility of human’s body (Hartman,2014). Our bodies can shake, bend or

Week4: Review of "CONTEXTUAL DESIGN"

The article explained what is contextual design and details of all steps in contextual design. The article claims that by applying contextual design in the work, the working team can communicate better and product a product or technology which match the customers' need more. Contextual design with start with interviewing customers to know their working habits; then use a work model to structure up their habit thus the team can understand it; and then the team should gather more amount of data and map it out to see the characteristic of large population of customers; by knowing the characteristic of customers, design team can find technology which can improve the customers' work and redesign their workflow; at last the team should also test with the real user to optimizes the system. In my opinion, as I do not have the experience that work in a large design team, I have never tried or encountered with contextual design. But I think it is a brilliant way to do interface desig

Week 3: Review of "HEURISTIC EVALUATION OF USER INTERFACES "

This paper tried to found out features of groups of people doing heuristic evaluation on interfaces design. And it gives out the result that there are not really a "absolute good evaluator"  or a  "absolute poor evaluator". As different person will have different perspective to look at things. The same design may become a usability problem to some groups of people while the other groups of people may not consider it as a usability problem. So, heuristic evaluation should be done with people from different characters and background. This paper has a bit inspired me, as I always think that people that spots more problem means that their are more smart. And the company should hire these kinds of people to do the heuristic evaluation. But this paper told me that I have overlooked who are the real users. Every individuals perceive the world in different way. If the user are the mass, we will never know what problems that they may encounter. So, we should evaluate every

week2: Reflection on "Norman, 2002. The Design of Everyday Things."

In the starting of chapter 3 of the book, Normans claims that people's behavior will be constrained by the information in the world, old memories in their brain and the cultural habits.  Thus, people may found confused to use new apparatus or product especially which are made from the other countries. And I think he is right. I deal with varies software and operation system during my student life in SCM. And all the hotkeys of them are different, which makes my feel confused and frustrated to use. For example, I have been used Win OS for more than 10 years. My brain tells my that when you scroll the wheel of the mouse up, the browser page will goes up. But in Mac OS, it is in reverse. When you scroll the mouse wheel up, the page go down. And it has bothered me a lot when I were using Mac OS. Another example is the Adobe Photoshop. Before I used the Photoshop, I knew that Ctrl+z will be the hot key to undo the action in any software. But in Photoshop, you need to press Ctrl+Alt+Z
