Week 6 - Design The Look Of The Android Application (Blinavigator)

assalammualaikum ..

task for this week is to design the interface of application with the method that been done last week which is swiping method .

Before this the interface of that android application is by using the button that the blind people has to randomly  try touch the screen to know what buttons are on that screen . After randomly touch then they have to hold and speak the option . The use of this  method is  not efficient for them since they have to randomly touch . here is the old look of android application that been design before .

The old look of the Blinavigator there will be 4 buttons which is the first on the instruction of the page , connectivity button , navigation button and hold and speak button for the blind people to voice out their option from randomly touch the screen .  

For this week i have design new look of the Blinavigator which is i put all the pages separately and in order to get into each of the page they have to swipe instead of touching the screen randomly . 

this is the main page of the Blinavigator . Once the apps on , there will be main instructions  that will be written on the '' Text For Label 1'' . The instruction appear to let the one that responsible introduce the application going to read first the instruction and teach the blind people how to use it properly afterward . This is the instruction that going to appear once the application on

As we can see that there is ''direction'' word on the screen that will indicate the swiping method . If we are swiping left it will show at that box left , if we are swiping right it will show right  . 

In this main main menu if we are swiping left i intend to insert the voice of instruction and if we are swiping right it will go straight to the next page  which is connectivity page and the navigation part . 

This is designated part of the connectivity part with no function yet 

This is designated part of the navigation part with no function yet .

the task for next week i am planning to settle the part of connectivity without have to touch the screen because as for now the connection has to be done with touch and choose the button as previous idea . This is important to make the blind people easy to connect the smart device

.

week 5 = Swiping method of using android application

Assalammualaikum..

For this week i have set myself to redesign the application so then the application going to be more friendly user for the blind people and also i have change the use of power supply on my circuit .

Before this the system have been powered up by the use of USB that connected to the Arduino and i think i find the difficulty for them to reconnect then on the system again . So here the solution for the project for the short term which is use the rechargeable battery . The battery that i have been used is




 . As  we know that by having button to the android application make them wondering how to use the button on the application so i have been doing some research on other method to use the function in that apps instead on push on the button option .

After do some research on tutorial in the youtube i figure out that we can do some method of swiping
to make the use of this apps easier . For the first time i have been testing on the normal swiping method first without interfaced any function through it . So here is the coding for the swiping method in the Blinavigator .

from the figure above i am going to explain the working of this coding . Canvas is a feature that we can use to move around on the apps . So when we choose the canvas from the option given in MIT APP INVENTOR , choose when it flung ,it is because we are going to apply swiping method . 

first if is when we absolute get heading means once our finger touch the screen and move to somewhere it going to fix our initial location of finger . let say  the finger initial less than 45 degree means the finger ready from the left side and swipe to right . it will decide that the situation is it is swiping to right method . then it will print to the text box ''right'' .. the same concept applied to the swiping left . 

we move on to the swiping up method , as we can see that the absolute heading is in between 45 and 135 which means our finger that touching the screen is at the centre and going to move to the positive up so the apps going to decide that the finger is moving/swiping up. 

Here is the simple design in confirming the functionality of the idea .

After functionality of the swiping is confirmed we put the same kind of procedure to the application . But still we have to rearrange each of the page and what page is going to be used in our apps.

For the next task i am going to redesign the pages that going to be used in the application and apply the swiping method to it .

week 4 - 3D PRINTING FOR COMPONENTS BOX

 Assalammualaikum for this week i have met Dr Azraie who is the lecturer of Icole Unikl BMI to print the design of my box . Dr Azraie is in level 3 . The printing process took 3 hours .  After 3 hours of printing the one that handle the printing process make a mistake to my printing box .

this is the final look for the box from side. There should be a divider to divide 2 compartments , but the one that in charge pull the divider together with the printed support for box . 

this is for the power supply port ,

this is the look of the lid with holes that fit perfectly for the sensor . 

After checked all the components of the box that been printed . I tried to fit all the components together . So here is the look after fit them 

From the figure above we can see that all the components fit in that box , Since the divider of the box has been pulled out i put the foam to divide those 2 components and i sealed it carefully to avoid short circuit . 

that is all task for this week . For next week I am going to change the use of power supply from use the USB CABLE of android to the battery and i want to redesign the look of my application to make it more friendly user to the blind people since last semester i used the application with button . 

week 2 & 3 - Designing the Components'box

Assalammualaikum..

For these 3 weeks including the first week i have  been designed the box with compartments to  place all the components from the hardware part  so then it can be seal together properly to our wrist band . I took 3 weeks of designing the box because i am a medical electronic student . we do not been exposed by the basic of designing so it took awhile for me to learn by myself all the feature that i want to add to my design .

Before i design the box that can fit perfectly to our wrist universally ; not too big not too small , i have been researched and look for the architecture measurement of the components that going to be placed

 as we can see that the measurement of Arduino for the lengthis 1.7 inches (4.318 cm) while for width it is 0.73 inches (1.8542 cm) . In placing this i planned to place it horizontally to the box . 

 this is the measurement of bluetooth , the length in 3.7cm and the width is 1.5 cm . For this part i am planning this component vertically to the box on  the first compartment of the box . 

After considering the sizing of components , here the design of the box . 

we can see there will be power supply port ,compartment 1 to fit the bluetooth component, component 2 to put the arduino Nano , and at the lid will be a circle that fit perfectly the size of the sensor .

the main reason i design this box with perfect size for all those components is to make the user comfortable while wear it with the wrist band . After consider the size of all components , i decide to make the size of the box is 5 cm x 5 cm x 5 cm for length,width and height respectively . I  hope the printing process for my box going to be ok . 

next task is i have  to meet Dr Azraie to print this design and attach it with the wrist band  .
