More information about the concepts can be found in section 5.2.1. The report is printed by Chalmers Reproservice Göteborg, Sweden 2011 Universal Remote Control for Smartphones Development of a communication station ANDERS GÖRANSON CHRIS NILSSON Department of Product and Production Development Chalmers University of Technology ABSTRACT This master thesis report describes the concept of a universal remote control for smartphones, with a focus on the development of a communication station with hardware needed in order for such a product to function as intended. The development starts with a “blank canvas”, and the resulting product functionality and design is based on an extensive market analysis conducted at the start of the project, including an analysis of current trends and competitors, as well as the thoughts and ideas of approximately 300 potential customers. The development process is based on the methods taught during the two years of the master program Product Development at Chalmers University of Technology. The project ends with the construction of a prototype able to demonstrate the product’s functionality. In addition to this, a set of design concepts are developed in order to come up with a product that people would want to place visibly in their living room. The product is developed in close collaboration with another master thesis group, focusing on the development of an end user interface in the form of an Iphone application. Keywords: product development, smartphone, universal remote control, embedded system TABLE OF CONTENTS 1 Introduction

User can control appliances easily by his Smartphone via Bluetooth. Around 71% of mobile developers use Android platform attributable to the recognition and extra features of the system. Phones are called smartphones only when applications like GPS, Video calling are embedded into the device. This paper combines Android, Bluetooth and smartphones which are three powerful technologies. Today’s world without a Smartphone is very complex. As a result, we have combined the Remote control with the Smart phones and provide simple user interface, rather than complex number of buttons which we have seen in many universal remote controls. KEYWORDS:Universal Remote, PIC Micro controller, Bluetooth, Android, Smart Phones, Network. I.INTRODUCTION Nowadays, the number of appliance services and their complexity has increased. There is a need to get familiar with the different operations of many remote control manufacturers, which is very confusing.
