Abstract
Innovator was formed by three students of Universiti Sains Malaysia (USM). The
company proposed a device, the Intelligent Air Conditioner System (ICONS) which is
connected to the air conditioner and a personal computer. ICONS will automatically
adjust the temperature of the room Lt will also automatically switched on the air
conditioner when a person enters the room and switched off the air conditioner when
there is nobody in the room ICONS, consists of two parts, the controller box
connected to the air conditioner and the software, programmed using the Fuzzy logic
algorithm installed on a personal computer. Cost saving features is one of the
marketing strategy used to promote the product to the public. Innovator promotes the
product via internet, email, website, social network, the Internet and exhibitions. The
unit cost of LCONS is sold at RM350.00 per unit. Sales projection for year one, two
and three are RM420,000, RM840,000 and RM I ,680,000 respecti vely. The uniqueness
of ICONS, is its ability to optimize the electrical usage. An analysis of the cost and
energy consumption of appliances results show that air conditioner connected to the
ICONS box and the computer would save more than 15% of the total electric bill. A
technology acceptance research on ICONS has been carried out through a survey with a
sample size of 100 respondents This research applied the correlation and regression
analysis to study the user acceptance of ICONS. The correlation analysis showed that
all variables are positively correlated. For the regression analysis, all the null hypotheses
are rejected. Finally it can be concluded that users accept the use of ICONS into their
household .
