* The first gas stoves were developed as early as the 1820s, but these
remained isolated experiments. James Sharp patented a gas stove
in Northampton, England in 1826 and opened a gas stove factory in 1836.
At the World Fair in London in 1851, a gas stove was shown, but only in
the 1880s did this technology start to become a commercial success. The
main factor for this delay was the slow growth of the gas pipe network.
* First patents date from the early 1900s. Demonstration stoves were
shown by the Frigidaire division of General Motors in the mid-1950s on a
touring GM showcase in North America. The induction cooker was
shown heating a pot of water with a newspaper placed between the
stove and the pot, to demonstrate the convenience and safety. This unit,
however, was never put into production. Modern implementation in the USA
dates from the early 1970s, with work done at the Research & Development
Center of Westinghouse Electric Corporation at Churchill Borough,
near Pittsburgh. The stand-alone single-burner range was named the Cool Top
Induction Range. It used paralleled Delco Electronics transistors developed for
automotive electronic ignition systems to drive the 25 kHz current.

* The purpose of this study is to evaluate the
usability o the gas stove and inductive stove in
terms of:
* Learnability
* How quickly the user complete the task?
* How satisfied the users in doing the task?
* Which of the two (2) units is much preferable by
the users?
* What are the recommendation s to improve the less
preferable?

4. *
* The respondents of the study are the proponent’s
neighbor that are at least 18 years old but no more
than 50 and who were not able to used any of the
two(2) product to be evaluated . There are five
respondents in this study. All respondents must know
how to fried scrambled egg . There are asked to
perform a task such as:
* Turning on the stove
* Fry scramble egg
* Respondents will evaluate their subjective experience
with both type of stove after completing the task. The
researcher measure their time in minutes and seconds
consumes in performing each task.

5. *
*There is a limitation with regards to the
materials used in conducting the study.
The materials use for both stove are not
the same. The inductive stove only allows
the specific cooking materials or utensils.
And the materials use in the gas stove is
different too. The inductive stove was set
to a certain temperature, for frying the
scrambled egg 250 degree Celsius will be
used.

* Procedure on task 1:
1. Insert the plug to electric socket
2. Turn on the stove and adjust to 1200 degree Celsius
* Procedure on task 2:
1. Heat the fan
2. Put an oil(edible)
3. On the other hand scramble the egg and add salt
4. When heated, put the egg
5. If it’s already golden brown turn off the stove
6. Take the scrambled egg to the fan

9. *
* For Gas stove:
* Procedure on task 1:
1. Opening the gas tank (turn the knob of the gas tank)
2. Ignite the burner(turn on the stove knob)
* Procedure on task 2:
1. Heat the pan
2. Put an oil (edible)
3. On the other hand scramble the egg and add salt
4. When heated, put the egg
5. If it’s already golden brown turn off the stove
6. Take the scrambled egg to the fan

* Using the study objective as the criteria, the
researcher analyze the data and come up to a
finding.
* The inductive stove is much preferred by the user
and find it easy to use.
* With respect to the time in performing the task,
the inductive stove is much faster and rated in less
time.
* In turning on (task 1) gas stove has less time.
* In frying (task2) inductive cooks faster.

18. *
* In this usability study of inductive and gas
stove, the researcher was able to gather
data base on the task given and evaluation
tools to check the usability of the product.
With this, researcher conclude that
inductive stove is preferred most of the user
instead of the gas stove. inductive stove it
satisfy the users in effectiveness and
efficiency.

19. *
*In the context of this study, the researcher suggests
the following recommendations:
*In the layout off the gas stove , the edges of it
should be round. For easy cleaning.
*There should be an added weight to the stove so
that when turning the knob there's no need to
hold to stop it from moving.
*In the inductive stove there should be a signage of
what temperature to be used to a certain food.
*The design and tools to be used should not be
limited. A specific utensil to be used is
discouraged.
