Voice Recorder - Software Prototype

February 12th, 2008

The goal of this week assignment is to make a better prototype based on the experience of user test with paper prototype. At least, to me, this is the focal point. (I had thought about whether I would focus on new idea with new device or software version of a new voice recorder interface. Then, I choose the latter part.)

I can’t tell that this prototype has perfect interface and work perfectly. I am still working on it. But, I put emphasis on the size of screen of the recorder, principle of new interface, and role as a software prototype, and beauty.


week3 -Assignment

February 12th, 2008

This week, again, I have been trying to figure out what ’s going on Java in Eclipse. Tree map for storing data, making a data structure is getting clear little by little. However, I am still confusing because even though I understand some code, a lot of classes and objects prevent me from which data I have to apply to or put on which part. I am in the fog of the Java language. Anyway, I put my confusing and my all misunderstanding of the first and second week on the back, I decided to make thing simple. So, with a help from ConcordanceProcessing.java, I made it. The size of circle is the number of a word. Here is the code

Voice Recorder - Improve & Observe & Conclude

February 5th, 2008

According to the problems of the Voice Recorder, I would change most parts of the interface. First of all, power button has to be separated from the others and play button should be with stop button not with menu function because procedure has nothing to do with each other, which means that, to change a function, user has to go to menu and forward to choose function and back to the play button to out of the screen. Moreover, to reduce the number of buttons, the button of erase and folder would be put inside of the menu. And, forward and backward button should turn into the scroll bar to easy to operate.

New prototype test

Conclude

After testing new interface, users said that they feel more comfortable not only because reduced the number of buttons but also because wheel bar in the side of the device. The more functions, the less beauty of design. right. Balancing is quite tough. Even though I come up with this interface idea, I want something different.


Voice Recorder - Predict & Observe

February 1st, 2008

A. Predict

DIGITAL VOICE RECORDER -SAFA (MODEL : R-200)

This device is for recording sound, especially human voices. I felt it is hard to figure out how to deal with erasing specific data and making its environment for getting data what they want.


Task 1. : Erase the No.12 data
Buttons : [P]ower [F]oward [B]ackward [E]rase
Notation : press release * repeat task s- seconds to complete
[P↓]1sec + [F↓↑ ﹡12] 10sec. + [E↓↑] 1sec + [E↓↓↑]3sec = 15 operations over 15secondsTask 2. : Go to the Menu and find Sense and change Lo to
Hi (or Hi to Lo).
Buttons : [P]ower [M]enu [P]ower([P]lay) [F]oward [B]ackward
Notation : press release * repeat task s- seconds to complete [P↓] 1sec + [M ↓↓3sec↑]3sec + [F↓↑ ﹡2]2sec +[P↓↑]1sec + [F↓↑](or [B↓↑])1sec + [P↓↑]1sec + [M ↓↑]1sec + [P↓↑] = 9 operations over 10seconds


Demonstrating Video 1
Demonstrating Video 2

Analysis
☛ If someone use this product for recording something, it must be making people get annoying. Repeats of operations is quite many and the order of operations is totally repeated irregularly. Besides, how long do people have to push the button is important elements of this device for operating. Thus, people who don’t know about all this functions and order can be lost. Especially, when I want to erase specific data, usually I push the erase button longer than I expected. It makes one of the sections that divided into 4 flickering and then is erased all data.

B. Observe

Observation of user is really interesting to me. Those who had a time with the digital device were trying to doing the tasks. Because of those trials, I think, I could peep people’s using process of the products. It was fun. However, Capturing video is not good, actually horrible. I regret not to capture people’s behavior after checking environment and state.

User1(Task 1)

User1(Task 2)

User2(Task 1, 2)

User3(Task 1, 2)

Analysis

☛ Unlike my expectation, people can do Task2 better than Task1. I expected reverse way because there is erase button sign. Also, most users have a problem with going into the sub-menu with menu button. Pushing button is not enough. Button has to be pushed for about 3sec.

I think designers in the company want to put all interface on the front side of the recorder. But, It was mistake. It’s too complicated. First of all, it has to be divided into power and the other interface because sometimes I push  the play button rather than turn off the recorder. And also, it has to be made by choosing whether they make more button (which is bad, though) or they have to be narrow down a standard (for instance, it has to be push the erase button longer than first push)


Prototype of the clock for blind people

January 31st, 2008

This work is the third idea of the clock design. The first reason that I choose it for making prototype is easy to demonstrate.  I ‘d like to explain this watch more(bigger version). It was supposed to be vacuum state when people check the time, which means that  it normally doesn’t look like a watch. However, people push a button, then, though the rubber on the top of the watch, the number come out and could be recognized. Inside of the clock, the real number’s turning all the time.  ☺

JOHN CORWELL, SAILOR AND MINER; and POISONOUS FISH

By Louis Becke

T. Fisher Unwin, 1901

JOHN CORWELL, SAILOR AND MINER

I

“Am I to have no privacy at all?” demanded the Governor irritably as
the orderly again tapped at the open door and announced another visitor.
“Who is he and what does he want?”

“Mr. John Corwell, your Excellency, master of the cutter _Ceres_, from
the South Seas.”

The Governor’s brows relaxed somewhat. “Let him come in in ten minutes,
Cleary, but tell him at the same time that I am very tired–too tired to
listen unless he has something of importance to say.”

The day had indeed been a most tiring one to the worthy Governor of the
colony of New South Wales, just then struggling weakly in its infancy,
and only emerging from the horrors of actual starvation, caused by the
utter neglect of the Home authorities to send out further supplies of
provisions. Prisoners of both sexes came in plenty, but brought nothing
to eat with them; the military officers who should have helped him in
his arduous labours were secretly plotting against him, and their
spare time–and they had plenty–was devoted to writing letters home
to highly-placed personages imploring them to induce the Government
to break up the settlement and not “waste the health and lives of even
these abandoned convicts in trying to found a colony in the most awful
and hideous desert the eye of man had ever seen, a place which can never
be useful to man and is accursed by God.” But the Governor took no heed.
Mutiny and discontent he had fought in his silent, determined way as
he fought grim famine, sparing himself nothing, toiling from dawn till
dark, listening to complaints, remedying abuses, punishing with swift
severity those who deserved it, and yet always preserving the same cold,
unbending dignity of manner which covered a highly-sensitive and deeply
sympathetic nature. ……………………..

Designing Clocks - w1

January 25th, 2008

<< clock/watch design for blind people >>

The first constraint during the first class of Designing For Constraints was time. I have to come up with the idea designing clock for blind people or just people for 10 minutes. It was an incredible experience because I have never designed anything for productions.

1> My first thought was “clock spring”. The spring inside of a clock drives hands outside of the clock. So, I decided to make a clock inside out. If I show a spring as a hand itself, I can make a clock not only getting visual appearance for people but also recognizing feature for blind people. Each hand has each length of the time such as 1 inch for an hour, 1/4 inches for a second…etc. To point out certain time, they have different speed and folding shape.

* Think about it ! - If this clock is on the business meeting table, it makes people nervous because of the shape. (during the class from Amit Pitaru )

2. 3.

2> Is there anything that blind people can see? This is the clock that can be recognized by light. I ‘d like to see something by light, too. because I like to feel sunlight. Moreover, for the blind, black glasses like sunglasses could be brought all the time. So, How can they know the time? if they push the buttons on the one side of the leg, depending on which button they push, they can feel the light passing by in front of their eyes. According to direction and times, the blind know the time.

But, to recognize the light well, the shape of the glasses have to be devised like goggles to block natural light.

3> I like the device that can be touched and told about their information. So, the third idea is that the blind people can know the time by touching surface of the watch. The watch tells the time with a shape of embossed number when people push one button in the watch. Like the stamp which can change the date, year, and month, the time can be changed by time. (The surface of the watch is flat and just like box)
