INTRODUCTION

Computers have brought up a revolution in the past twenty years. 

They have taken place everywhere now and then they are being used 

by everyone. Most of our day-to-day jobs are being influenced by the 

use of computers. They are playing important role in our daily life and 

providing facilities which are beyond our imagination. Human 

Computer Interaction is a branch in which developer makes user 

friendly system. Human beings have a good grasping and 

manipulating ability with their hands . Hand gesture is a very natural 

form of human interaction and can be used effectively in Human 

Computer Interaction (HCI). Very simple and common interfaces are 

represented by mouse and keyboard by which a user interacts with 

the personal computer machine. In the last few years, new interfaces 

have been developed such as stylus, touch screen, voice recognition 

but they have some pros and some cons. Therefore mouse is still 

referred for GUI (graphical user interface).  Many of us suffer from 

RSI (Repetitive Strain Injury) like pain in forearm, shoulder and back 

as we use mouse for hours on end. Researchers have known for 

years that interactions like pointing operation, clicking operation and 

dragging operation are not ideal forms of interaction for many tasks.  

The most important injury related with using a mouse is Carpal 

Tunnel Syndrome. This is caused by putting the wrist on a hard 

surface while using mouse. This pinches the nerves that are passing 

into palm, specially the median nerve. This causes excruciating pain 

and tingle, which can usually only be healed by surgery (and many 

times it will not heals completely). It is necessary to develop the 

wireless "user-friendly" and more efficient system for Human 

Computer Interaction. The proposed system makes the use of flex 

sensors and accelerometer to sense hand gestures, and according to 

hand gestures it will perform typical actions such as left click, right 

click, drag operation, rotation operation and pointing operation.  The 

aim of this project is to work with accelerometers and translate the 

motion of the hand into various applications in a virtual interface. It is 

most intuitive for us to use things based on our hand motions, as they 

form a very basic form of communication, signaling and gesturing 

computer's mouse pointer, having all the standard functionalities as 

that of a computer mouse, left, right, middle click and scroll. Unique 

combination of finger movements that are very similar to the current 

mouse usage behaviorally would represent each of these.

"A wireless computer pointing device with glove-

based controls and user preference selectability"

The final project, designed and built a wireless computer pointing 

device with accelerometer based movement control. The  

implementation allows the user to wear a set of hardware (a glove and 

connected armband) and control a cursor through different hand 

orientations and finger presses. Users can operate their computers 

with their hands in midair without the hassle of desks surfaces or 

The project altogether comprises  both  hardware and software  

An accelerometer is device that measures acceleration forces. 

Forces may be static, such as the constant force of gravity, or they 

may be dynamic – due to movement or vibration of the 

accelerometer. The amount of static acceleration provides the tilt 

angle of device with respect to the earth. The amount of dynamic 

acceleration provides the information about the way the device is

CONCLUSION

Overall, the results of our project met our expectations 

outlined in our project proposal. Our final prototype is able 

to effectively control mouse movement and clicking with 

user hand gestures. 

Despite our satisfaction, we were not able to achieve one 

goal we had set at the beginning of this project. Initially, 

we had envisioned our glove to be able to control mouse 

movement by position of the glove in a 2-D plane. This 

design would have been more intuitive and similar to the 

existing paradigm of standard computer mice, lowering the 

learning curve associated with using the Glove Mouse. 

After spending several hours on this endeavor, we 

realized that we would probably not be able to integrate 

our accelerometer output to extract the data we needed in 

a useful fashion. With the grade of parts that we could 

afford with our budget, plus the short amount of time we 

had, we decided half-way through the project to shift our 

efforts towards controlling the mouse cursor with 

accelerometer tilt readings instead. Since we suspected 

this difficulty at the start of our project, our realistic 

expectation was to try 2-D positioning, but plan for tilt-

based movement control as an alternative. Thus, we feel 

as if the expectations of this project have still be met.

The final prototype created from our 4 week project serves 

as a additional proof-of-concept to similar existing 

projects. Because of this, we believe that this design has 

much room to grow. Primarily, we believe that a smaller 

wearable unit (for example, a single glove without an 

armband) would be more practical for everyday use. Our 

project is built with a small budget in mind and with easily 

usable, but not necessarily the smallest, parts. With more 

time, a custom PCB could be used to simplify the physical 

construction. Additionally, higher resolution cursor 

movement could be attractive for commercialization.

No designs were reverse engineered in the creation of our 

project. As mentioned already, we utilized the Teensy C 

libraries for proper USB HID communication. We also 

built-off the idea of arm-mounted circuit used in previous 

glove-based projects. This project would not have been as 

successful without the confidence provided by previous 

student projects. As a result, we want to forgo any patent 

opportunities related to this project, and leave our work as 

a open-source basis for any related future student or 

hobby projects.
