Description
Provide a description of your
design using no greater than 1000 words and 10 images. Describe the important
features of your design, including both display features and interactions.
Describe how it will enable investigators to quickly understand new situations,
think deeply to develop and test their theories as part of their investigation,
and rapidly reorient their investigation when data or assumptions change.
The design has three major displays. They are designed to be
compatible with touch-screen devices such as tablets and smartphones to provide
investigators mobility, if needed, and an easier way to interact with the
programs. The first display gives a general overview of the conditions on the
island. The second gives a more specific, but still general, overview of the subset
of VIP members each investigator is assigned with. The third display is a
search database that can look up, compare, and contrast people based on the
search settings.
The first display is accessible to all investigators and
shows an overview of the overall security of the island in real time. Regions
of the island blinks in red to indicate that the investigator’s attention is
needed in those areas because of high suspicious or criminal activities. The
bar on the very right demonstrates the overall security level of the island
accumulated from various camera, police, or financial transaction reports. The
blue levels of the bar fluctuates depending on
criminal or suspicious activity and overcrowded regions.
On the left side of the display are features the
investigator can select to appear on the map. The investigator can view
population, crime, and anomaly density and track specific groups of people.
Anomaly density represents locations where there is deviation from the regular
pattern of movements or activities.
Another feature allows the investigator to select regions of
the map to zoom in. These features help determine the location, validity, and
urgency of the alerts.
The last feature allows the investigator to select a
building for a detailed report on its activity levels. The activity detection
is based on information such as times of events, financial transactions, key
card entrance record, news reports, and the weather.
The entire building is shown in distinct red, white, and
purple color schematic in order to easily convey this information and quickly
alert the investigators to take notice. The red indicates extremely high
activity while the white indicates no activity. The purple indicates anomalous
activities which could indicate that a person is inside a room where he should
not be or that he has been in a room for an excessive period of time. This
feature has the option of viewing changes in data over time. The video
progress bar has green tabs in which an investigator can enter a start and end
time to view changes over time. The play bar will show the data change over
time and the stop button will pause the data at a specific time or data frame.
Hovering over the red button will indicate the specific date and time of the
what is displayed on screen. The time progress bar is to help the investigator
to detect any patterns in activity and readily access old data.
The second screen is a collection of a subset of locations
that the investigators are assigned to. The major purpose of this program is to
secure the safety of VIP members. In each grid, the exit labels are marked and
the VIP members are indicated in green. Criminals or suspects have a red circle
around them and the radius of the circle differs depending on how dangerous
they are. When the VIPs enter or touch the red circles, the VIPs change color
and blink. The program then immediately calculates and demonstrates the nearest
route to the exit and an “Alert VIP” button appears. Pressing the button will
send information regarding the nearest exit and that the VIP is in an unsafe
area to security officials who will help guide the VIPs into a safe direction.
This program also has a time progress feature which works in the same manner as
described above.
The third display is a search tool for investigators to
navigate through the huge database and report sources. The search bar on top of
the display zone help investigators to keep track of each individual. If an
investigator wants to know what happened to a specific person in a certain
period of time, he can type in the person’s ID number (each person on the
island has a unique ID number), mark the person’s type (He might be a VIP, a
suspect, a criminal or just a normal person), and select the time period they
want to look up.After selecting a person, there will
be a line displaying next to his ID number, which represents his/her activity
status during the selected time, in which white means no activity, green means
normal activity and purple means weird activity. Investigators can search for
several people at the same time, so that they can compare and analyze their
movement (For example, if several people are planning a crime together, they
may show weird activity at the same time).
By selecting one or more people and clicking the “track”
button, the screen will display the paths of these selected people.
Investigators can get further information about where these
people are based on time using the time progress bar.
Clicking the
“Predict” button will demonstrate circular regions that demonstrate where each
person will most likely be based on past behaviors. This “Predict” button is
useful because it can help indicate if a person is demonstrating weird location
patterns and create a preemptive measure in which security can guide VIPs away
from the circular regions created of the suspects and criminals.
