Midterm Exam: Computer Human Interfaces 1/2010 (CPE)

Midterm Exam

204482 Computer-Human Interfaces 1/2010

Instructions

• Write your answer in either Thai or English.
• Closed book!
• Closed note!
• There are 10 questions. Each has 10 scores. Answer all questions in given exam booklets. Do them all.
• Note that you obviously need to use your common senses to answer the exam; however, only it is not enough to get scores.  References, evidences, causes, rules, laws, theories, and your justifications are supposed to be mentioned.  Any design scripts without good explanation will not get good scores.

Exam

1. Information system in KU has many troubles in collecting correct data from students.  For example, some students may not want to give correct ones.  If we asked them to fill the form online, the information will not be reliably correct.  If we hire typists to fill information from official documents that students have submitted when they admitted to KU; the typists may make some errors as well.  However, KU still wants correct information of students, such as current address, phone number, recent photographs, etc.  Give your ideas how to solve this problem.
2. You might have troubles to go to have lunches in the university (like me.)  I believe that you might face problems: 1) long time to select what you should eat, 2) hard time to order food with long queue; and 3) frustrating time to get place to eat.  Since there are two cafeterias in the Faculty of Engineering, that would make you more headache for dining.  Since you are a user-interface engineer, design the new interfaces of the cafeteria in order to make all of us have a better lunch time.
3. The CPE building has two famous elevators (lift) for its fast door closing.  If you have to design the speech interfaces for elevator control, design an appropriate “speech command suite” for communicating with an elevator-control module in order to make passengers feel the most comfortable in the elevator transportation of the CPE building.
4. If the class of HCI is “a kind of computer”, where its objective is mainly to teach students to understand the importance of the computer design, you are asked to redesign the user interface of the class.  Write your concept proposal of your design.
5. Is the webcast of lecture, such as an available one in the CPE department, important for education?  What are the reasons that a student has to go back to study on it?  Do you have any ideas to make it successful? If so, how?
6. You are assigned to create an online student manual booklet in order that KU students can access correct and updated student regulations with its easy explanation.  Explain what is not good in the booklet and give the concepts of your new design and development.
7.  In almost every car, you found that your car can be controlled by a steering wheel in Figure 1(a); however, the steering wheel of most ship looks like the one in Figure 1(b).  Since you are a user-interface designer.  Discuss the both wheels on: the reasons that brings them different; the control efficiency in case we swap the wheels between car and ship; and the future of both wheels. 

(a)	(b)

Figure 1 Steering Wheel; a) car and b) ship
8. As you are a KU student, you have to use many separated information systems.  I know that you might not “enjoy” it.  Therefore, redesign the user interfaces for KU Computer. Engineering students (not general KU students) in order to make most students enjoy your design and development.  You also have to give a definition on the “enjoyment.”
9. How many types of communication and collaborative software are there?  Supposedly, you have to find that kind of software in order to improve higher education, such as in university, what are you going to do?
10. Why we need virtual environments?  Give an example of the situations.

Exam

1. (20 points) A company owns a very large Thai-style Sukiyaki restaurant chain widely located in the country.  Its main business is about food service.  They serve raw food products, such as meat, pork, meatball, and vegetables, for customers to cook as Sukiyaki at their table and a wide range of alacarte, such as roasted duck, dim sum, and sweets.   Basically, there is no food stocked at each restaurant.  Both raw food and pre-cooked alacarte are prepared at factories located at each province and then they are delivered to the restaurants every morning.  Each restaurant has different size; therefore, amount of food to be delivered is not equal.  Because eating habit of people is different from one to another area, the estimated amount of food on each day in week is not necessary to be equal; for example, people in office area will go to restaurant during day time and people in living area will go during weekend.  Consequently, food preparation at the provincial factory will not be equal.  In the company organization, there are two positions that are responsible for food stock: provincial manager and country manager.  The provincial manager is responsible to prepare daily package to each restaurant in his/her province.  The country manager is responsible on material logistics to the whole country; he/she has to know statuses of both provincial factories and local restaurants.  You are a software engineer and your boss asked you to design an online visualization for (1.1) provincial factory manager and (1.2) country manager. 
2. (10 points) Since you are a computer expert, you are always asked from family and friends to buy a computer.  However, you cannot remember everything about new products.  Generally, you search information, such as specification, price, and expert reviews, from a search engine, like Google.  After you get all information, you have to painfully compile it before you make a final suggestion.  Now, supposedly you can get on-line information of every computer, Design a user-interface in order to ease you to make a selection.  
3. (10 points) Describe following types of documents: FAQ, Online help, Context-sensitive help, User manual and Reference Manual.
4. (10 points) Currently, you can see that a product using new technology can replace the old one.  For example in camera, film is replaced with flash memory.  Discuss whether a computer tablet, such as Apple iPad, can be a replacement of paper or not. 
5. (10 points) Explain what are the complex potential benefits and dangers of using color coding.
6. (10 points) Explain the model of response time and impacts on to quality of service.  What are short-tem, long-term, and working memories?  Explain it with examples.

1. Why do we need to study and do research on the field of human-computer interfaces?
2. What are usability measures? Explain them.
3. Design a job resume for yourself in order to get a position of a computer engineer. Make a good field layout and write excellent resume content. Explain what your future boss will think about your resume. You can put false (looks likely to be true) information in order to make your resume look very attractive but you have to underline it.
4. Actually, a car driver cannot use any computing/communication devices while he/she is driving because of safety reason.  However, the driver sometimes still requires querying information like GPS.  Parking for browsing is currently forced by law; however, querying while driving is more usable but safety.  That might be because the design of those devices is not good enough.  Therefore, you are asked to design more appropriate interactive input/output devices for car driver.
5. Design user-interfaces for bathroom and toilet. You have to define their usages, specify who the users are, review your design objectives, and give description with explanation on your design.
6. Information system in KU has many troubles in collecting correct data from students.  For example, some students may not want to give correct ones.  If we asked them to fill the form online, the information will not be reliably correct.  If we hire typists to fill information from official documents that students have submitted when they admitted to KU; the typists may make some errors as well.  However, KU still wants correct information of students, such as current address, phone number, recent photographs, etc.  Give your ideas how to solve this problem.

สรุปสั้นๆ ของน้ำท่วม ๒๕๕๔

ต้นฉบับพร้อมความเห็นใน Facebook

ข้อสรุป เหตุผลน้ำท่วม ๒๕๕๔

ขอสรุปสั้นสุด "ขาดธรรมาภิบาล"

แต่ถ้าจะขยายก็คือ

• น้ำไม่ต่างจากปี ๒๕๓๘ (แต่ตอนนั้น ไม่มีการจัดการ ไม่มีคันกั้นมากมาย มันก็ไม่ได้เละเทะแบบนี้)
• ให้ข่าวทุกวันว่าจัดการได้ (ดูเอาเองตามข้อเท็จจริง)
• ปิดข้อเท็จจริงจนหยดสุดท้าย
• ให้ข้อมูลโดยไร้หลักวิชาการ (เช่น "ผมเดาเอานะ...")
• มีข้อมูลที่ดีพอต่อการตัดสินใจ แต่... (ตามเว็บกรมชล ก็ได้ข้อเท็จจริงตามนั้นจริงๆ แต่การจัดการก็นะ หน่อมแน้ม สุดๆ)
• ให้ความสำคัญแก่นโยบายที่หาเสียงมากกว่าข้อเท็จจริง (ปล่อยน้ำเข้าทุ่งก่อนหน้านี้ ก็คงผิด concept "ลาก่อน น้ำท่วม น้ำแล้ง" ... ไม่อยากจะเดาว่าเดี๋ยวก็แล้งอีก ดูจาก performance รอบนี้)
• บริหารจัดการโดยใช้อำนาจ ตามผลของฐานเสียง (ขาใหญ่สั่งห้ามท่วมที่โน่นที่นี่ จนทำอะไรไมได้)
• ประเทศไร้ผู้นำที่เก่ง (มีแต่ผู้อยากนำ)

นักวิชาการกับการชี้นำสังคมในปี ๒๕๕๔

ต้นฉบับพร้อมข้อคิดเห็นของเพื่อนๆ เขียนไว้ใน Facebook

เหตุผลที่นักวิชาการ "ตัวจริง" ไม่ค่อยอยากให้ข้อคิดเห็นเชิงสาธารณะ

• คิดว่าให้ไปแล้วรัฐอาจไม่ฟัง แถมอาจจะโดนอาวุธหนักถล่ม
• แห็นว่าพวกออกสื่อมีแต่ให้นักวิชาการที่ไม่รู้จริงแต่ลีลาดี เลยกลัวคนมือดีในวงการจะเหมารวมว่า "อยากดัง" ด้วย
• มีชื่อเสียง เป็นภัยรูปแบบหนึ่ง สำหรับนักวิชาการ (ลองมองหาคนที่มีชื่อเสียงในมหาลัยและเก่งจริงในสาขาก็มีเยอะครับ เขาก็รู้มือกัน คนนอกต่างหากไม่รู้ แต่นักข่าวควรรู้)
• เพราะรู้ทั้งรู้คนเก่งในหน่วยงานรัฐตัวจริงก็มีเยอะแยะ แต่พวกนั้นไม่ได้โต หรือไม่ใช่พวกนักการเมือง ไม่อยากข้ามหน้าคนที่ตนนับถือ
• ยังจำเป็นต้องพึ่งพาจากหน่วยงานรัฐ ในโอกาสอื่น
• เสนอข้อมูลให้คนเกษียณแล้วพูดแทน จะปลอดภัยกว่า
• รู้ตัวว่าพูดไม่เก่ง เดี๋ยวชาวบ้านฟังไม่รู้เรื่อง
• กลัวโดนจับเป็นแพะ
• ให้น้ำหนักจรรยาบรรณมากเกินประโยชน์สาธารณะ เพราะไม่มั่นใจ ๑๐๐% ว่าสิ่งที่พูดจะเวิร์ค
• ช่วยเบื้องหลังดีกว่า เพราะมักคิดว่าถ้าเห็นเรามีคุณค่าเขาก็มาเองแหละ
• อีกที นักวิชาการไทยที่เก่งๆ คนวงในเขาก็รู้มือ งานก็เพียบ ช่วยงานประเทศชาติเบื้องหลังตลอด แต่สาธารณะไม่รู้
