Title: Project Preparation


1
Project Preparation
  • Loren Terveen
  • CS 5115, Fall 2007
  • September 12

2
Objectives for today
  • Hear about a set of project ideas
  • Deadline next Wednesday, September 19
  • Projects must be defined and
  • Groups must be formed

3
Hall of Fame / Shame
  • James Greensky
  • Fall 2006 Student

4
Blood Pressure Monitor (Aneroid)
5
Hall of Shame
  • Very difficult to impossible to form any
    conceptual model
  • Absolutely no constraints or few visibility clues
    as to how to use the objects or even how they
    relate
  • Some affordanances, but without a conceptual
    model they dont make sense
  • No feedback as to using the devices correctly
  • Must remember exactly how to use the devices
  • Very large Gulfs of Execution and Evaluation
  • Other Gulfs
  • - Even if you know how to use the device, very
    hard to execute the correct action
  • sequences without errors to obtain the
    results
  • - Easy to position cuff wrong, but the arrow
    helps
  • - Also easy to put cuff on too tight or too
    loose
  • - Easy to forget valve is open
  • - Needs full user attention to hear and
    remember results
  • - Interpreting the results requires previous
    knowledge
  • - Do the results make sense or is the cuff on
    wrong, better adjust cuff and retest
  • - Was the pressure for no heartbeat systolic or
    diastolic, often referred to by
    non-professional users of the device as simply
    the top and bottom numbers

6
Blood Pressure Monitor (Digital)
  • Much easier to form a conceptual model for the
    device due to a unified structure
  • Being able to form a conceptual model makes all
    the difference
  • Affordances make more sense
  • Much easier to figure out and after remember how
    to use the device
  • Much better visibility and feedback due to
    display
  • No longer requires users full attention
  • Can easily see the results and KNOW that the top
    number is systolic and the bottom number is
    diastolic
  • Less susceptible to error but

7
Hall of Fame???
  • Errors can still easily occur due to improper
    placement or fit of cuff
  • Easy to hit on/off button instead of start which
    instantly turns the tester off
  • Still need to have previous knowledge to
    interpret the results
  • - Is ???/?? normal, am I going to die???
  • Start button could be coded better

8
Blood Pressure Monitor (Wal-mart)
  • Excellent conceptual model
  • Excellent use of affordance
  • Excellent use of physical constraints
  • No Gulf of Execution

9
Hall of Fame
  • Buttons are culturally coded
  • Can easily interpret and evaluate results
  • No Gulf of Evaluation
  • A good design can make you want to use the device

Academic Calendar Builder
  • Jialei (Rebecca) Yan
  • yanxx106_at_umn.edu

18
Project Idea
  • Add course info to a Calendar
  • Hw due day, exam date, etc.
  • Group course info together
  • See all the info in one page
  • Customized interfaces
  • Colors, fonts, etc.

19
Revamping GRIT
  • Erik Bakke
  • bakk0167_at_umn.edu

20
GRITGrade Retrieval for the Institute of
Technologyor Gosh what a Really Irritating
Tool
  • GRIT is the current online grade system used in
    the Computer Science department. It allows TAs to
    enter scores to the database and students to log
    in and view their scores. We propose to develop a
    replacement for the current system.

20
21
Types of Users
  • Students
  • Check Grades
  • Receive feedback from assignments/tests
  • View statistics about assignments/tests to get a
    feel for how they are doing compared with the
    rest of the class
  • Professors/TAs
  • Provide a convenient way for profs/TAs to store
    grades
  • Enter grades for assignments and tests
  • Provide feedback for students

21
22
Current Student Interfaces
  • Frequently the weighted total is calculated at
    something greater than 100. Even when its
    right, the number is not accompanied by a letter
    grade.
  • The data is not easy to read for all types of
    users (i.e. those who prefer a graphical
    representation)
  • Unless the TA explicitly states it in the notes,
    there is no way to know where points were lost.
    This is partly because the system does not allow
    for sub-categories within an assignment. For
    example, say an assignment has a total of 20
    points. GRIT allows one field containing the
    total of 20 points. But those points are divided
    into the following groups 10 pts for completing
    the requirements, 5 pts for style, 5 points for
    compiling w/out errors. GRIT cannot convey this
    information.
  • Extra data is displayed whether the user wants
    it or not.
  • There is no way to switch between semesters,
    without leaving and coming back.
  • Students cannot dispute grades from the system.
  • Submitting assignments requires the use of yet
    another tool.

22
23
Current Professor/TA Interfaces
  • Paraphrasing CS Professor John Collins about
    GRIT
  • I simply created a spreadsheet and then wrote a
    program to convert the spreadsheet into GRIT
    files. Does this sound simple?
  • Some TAs have also voiced their complaints about
    interacting with the current system.

Why isnt this system simpler? Why is this
system only used by the Institute of Technology?
Is their a better way?
23
24
Proposed Improvements
  • Improved ease of use for Professors/TAs
  • Allow the Prof/TA to enter and update scores
    easily
  • Improved reporting for students
  • Allow the student to view the data in more useful
    ways (including graphs), and allow the user to
    hide unwanted data.
  • Improved interaction between TA and students
  • Allow students to submit assignments directly
    from GRIT.
  • Allow for things such as an easy way for students
    to submit a question or dispute related to a
    specific score directly from GRIT
  • Provide a What you need to do for a(n) _ grade
    tool.
  • Display the current best grade calculation for
    courses that allow different assignment weights
    based on dropping one or more other assignments.

  • Contact mattbroten_at_gmail.com

30
Campus NavigatorInteractive Campus Map
  • Vinod Krishnankrish055_at_umn.edu

31
Background/Motivation
  • Despite having maps, students still have trouble
    getting around the campus
  • Some get confused with dual entrances/exits in
    buildings
  • Buildings names are at the bottom (American),
    not immediately above the entrance (like in
    India, China, Japan, Singapore, etc.)
  • But the U has a large international
    presence-cater to their needs too
  • Get disoriented with directions-leads to
    frustration
  • Gopherway maps are not self-explanatory (Caught
    in heavy snow? How do I know if the nearest
    building has a Gopherway or not?)
  • How do I know if what I am looking for in the
    map, actually exists in the map? (Try locating
    TCF Bank on the map!)
  • You have Radisson but not TCF (lots of
    information- redundant but not always what you
    are looking for)
  • You are here how visible is this information?

32
Solution
  • The Campus Navigator will allow users to
  • To find out exactly where they are (You are
    here depictions using a distinctly visible
    pointer (on screen) or an LED on a public display
    outside buildings)
  • Ask what lies front of him/her, behind, to the
    left and to the right helps determine more
    precise position-oriented information (let them
    control and explore the interface)
  • Give school-to-building mapping information
    e.g. Smith Hall is where the School of Chemistry
    is.
  • Build a moderately sized database containing
    descriptive position information
  • When you are frustrated, you just like to be
    instructed to your destination

33
Solution (contd..)
  • The system doesnt have to (and is not intended
    to)resemble Google Earth/Microsoft Virtual Earth
  • Build a moderately sized database containing
    descriptive position information
  • Reduced back-end volume, quick solution, UI can
    be made as simple as that of a pager
  • Who cares about colorful pictures when you are
    out in the snow desperate to find a Gopherway?
  • Questions/Suggestions???

34

Class Web Page Manager
  • Adam Wolf

39
WebCT Hurts To Use
  • Iffy back button
  • Mishmash of file types, fonts
  • Feels like an exported directory

40
Goals
  • Follow web standards
  • Minimalist design for accessibility
  • Easy for students to get information
  • Easy for faculty and staff to provide information
  • Easy privacy controls (FERPA)?
  • Included templates for items to increase
    cohesiveness
  • Convenience features
  • RSS/Email notification
  • Export to iCal/Google Calendar

41
Grocery Store Guide
  • Susu Bordiano
  • bord0081_at_umn.edu

42
Problem What Can I Eat?
  • Dietary restrictions difficult to manage
  • Diabetes
  • High Cholesterol
  • Parents with children that have special dietary
    concerns
  • Food Allergies
  • Lactose Intolerance
  • Personal eating choices
  • Vegetarian
  • Kosher Foods
  • So much data to digest on the label

43
One Solution
  • Online Account
  • Maintains users dietary needs
  • Database of Food Items
  • User search or selection from list/group
  • Determine if foods match their profile
  • Create a shopping list of compatible items, with
    aisle numbers
  • Customizable Profile
  • User can add food items to their Favorites
  • System suggests recipes based on users custom
    profile

44
Details
  • Envisioned as a web-based system
  • Parents can maintain profiles for multiple family
    members
  • Children have moderate access their account and
    can add requested foods to a checklist for
    parents to review
  • Special profiles can be created for religious
    observations/fasting, training for athletic
    events, etc.

45
Hospital Registration System
  • Weijia Deng
  • deng_at_cs.umn.edu

46
What?
  • Purpose Provide the convenient way to fill in
    the personal health report, to make an
    appointment, to pay and buy medicine.
  • Desired Features
  • The registration interface for a patient
  • SW Interface for the hospital operator
  • The query interface for the patient

47
How?
  • (1) sign in, a new patient has to fill in the
    health report
  • (2) Check the doctor, time constraint to make an
    appointment
  • (3) either come to see the doctor or fill in the
    symptom online
  • (4) record the suggestion or solution from the
    doctor
  • (5) automatically calculate the debt
  • (6) choose the method of buying medicine, the
    patient can buy the medicine online and the
    hospital will deliver it

48
Gaming Convention EventRegistration System
  • Michael Miller
  • mill3608_at_umn.edu

49
Games Convention Event Scheduler
50
The Current System
  • Each attendee makes a list of events
  • Source Events Book or Con website
  • Search is eyeball, Index, or Ctrl-F
  • Options list kept via pencil or Notepad
  • No good way to specify preferences
  • In each time slot an attendee will get the first
    available event in their list
  • Often theyd rather specify different schedules
    or give priority to events that arent on the
    first day.
  • What about lynchpins?
  • Submitted via mail or e-mail

51
Solution Ideas
  • Searchable Event List
  • Title, game type, system, start time, etc.
  • Schedule Builder with visual overview
  • Create and compare different schedules
  • Able to specify priority for events
  • Most Desired Events/Event Ranking
  • More flexible options for If my first choice is
    sold out
  • If/then, option list, etc. (with complexity
    limit?)
  • Preferably Web-based
  • Submit online and share with friends

52
Craig's List Redesign
  • Abby Riesterer
  • riest036_at_umn.edu

53
Craigs List Facelift The Problem
  • http//minneapolis.craigslist.org

53
54
Why its so bad
  • To view a post, the user must leave the listings
    page and navigate with their browsers back
    button to return
  • While information is stored in a logical way,
    there is no easy way to mark posts as favorites
    or compare posts side by side
  • Search capabilities are severely limited

54
55
Even more reasons to redesign it
  • Creating a post is a long, convoluted process
    where the feedback is sent to you via email, not
    immediately on the screen.
  • No standard template for posters to enter more
    detailed information, like size
  • Its ugly.

55
56
I propose
  • Task-centered interface that streamlines the
    search process
  • Emphasize user accounts to allow storage of
    favorites, preferences, etc
  • Sort options so users can look at the
    closest/cheapest postings first
  • A new color scheme

Home Management
  • Pradeep Narayanashetty
  • pnshetty_at_cs.umn.edu

58
How is it going now....
I need to clean up my cupboard this weekend. .
58
58
59
Solution . .
  • A one-stop app to address your daily needs
  • A web-based tool useful for people who live
    together/interact regularly
  • Message board
  • Reminders
  • Personal Notes
  • Lending/Borrowing management

60
UI Challenges . .
  • A plain web application is no real challenge
  • Challenge to provide a user friendly interface
    that consumes minimum time
  • Customizable interfaces mean better interfaces !!
  • Availability of real users and hence better
    understanding of users needs and problems
  • And more . .

61
Student Class Scheduler
  • Tyson Malchow
  • malc0033_at_umn.edu

62
Student Class Scheduling System
  • Problem Students have many class options per
    semester, and no easy way to determine the best
    possible schedule.
  • Solution Create a website that would help
    aggregate all their data into one simple
    interface a system that would let them quickly
    and easily view schedule options for their
    selected classes.

63
Student Class Scheduling SystemFeatures
  • Allow for classes both required and optional
    wanted classes
  • Allow for constraints both time and credit load
  • Quick access to register for selected courses
  • Fast, simple-yet-powerful UI
  • Possible integration with friends schedules and
    classes
  • Even allow for class commenting whats good,
    hard, easy, requirement-fulfillment, etc. A
    one-stop place for creating your schedule

1. UI for Memory Impaired Users2. Image
processing task-based UI
  • James H. Faghmous
  • Depts. of Computer Science - Neuroscience
  • University of Minnesota Twin Cities

65
Overview
  • An Interface for mentally impaired individuals
  • A task-based UI for image processing software

66
Keeping them involved An Interface for mentally
impaired individuals
  • Why bother?
  • Five million people in the United States have
    Alzheimers Disease (AD). 2.5 million are at the
    early stages of the disease
  • Early onset of AD starts as early as 35
  • Not as productive, but still individuals with
    feelings nonetheless
  • Need to keep these individuals involved

67
One Approach
  • Take advantage of Minneapolis resources VA
    Medical Center (patients, caretakers) to design a
    prototype
  • Use a touch-screen interface
  • Could adapt to additional memory impairment
  • Open for suggestions

68
A task-based UI for image processing software
  • Why bother?
  • Advanced image processing applications offer
    hundreds of functionalities
  • Difficult to carry out simple tasks without
    prior software-specific training

69
One approach
  • Use open source image processing software
  • Develop a task-specific filter. Display buttons
    related to task only.
  • Not to be confused with the effect option

70
Interactive Image Quiz Maker
  • Fernando Torre
  • fernando.torre_at_gmail.com

71
Interactive Image Quiz Maker
  • Purpose Interface for designing quizzes that are
    based on an image or set of images. Areas or
    points on the images are selected and users
    answer questions based on them.

71
72
Applications
  • Mainly for use in education in areas such as
    Geography, Anatomy, Code Error Identification,
    etc.

72
73
Features
  • Quiz content editor that can modify images to be
    used, selections on parts of the image, and
