Project Progress:

The T-Pad assembly is complete and its performance was tested by directly supplying PWM signals of varying duty-cycles and it performed as intended.

We are still debugging the firmware issues with the PIC and the communication issues in between the T-Pad and the Kindle Fire. We plan to continue working on the project even though the project officially is completed as the Term has ended.

Project Progress Update

On May. 24th, group members got together and checked the missing component on the circuit board. Arjun had sent an e-mail to the designer for details of the missing capacitor. Designer replied that we need to use a multimeter to measure the capacitor of the whole circuit board and then decide which capacitor we should choose. After the measurement, we find out the current value of capacitor is 53nf and the wanted value is 58. So we needed a 5nf capacitor and put it in the parallel way to add the value of capacitor. However, we found out that we were unfortunately short for either 5nf or 10nf. So we decided to send the order list to Professor Yon Visell and ask for the capacitor. When the capacitor arrives, we can start our final test.

Project Progress Update:

Here are the update on the images of the different components:

The T-PaD:

The Circuit Board: (The circuit requires some final connections)

There has been a small delay in the assembly but the testing of the prototype will start next week to keep with the original schedule.

Update on the Development Schedule:

Check Point 1 - Assembly of the t-pad and the circuit by Tuesday (5/7/2013)

Check Point 2 - Assembly of the T-PaD Fire and software installation by Saturday (5/11/2013)

Check Point 3 - Testing 1 to be carried out by Tuesday (5/14/2013).

Check Point 4 - Corrections for problems found in Testing 1 and perform Testing 2 to be carried out by 

                         Thursday (5/16/2013)

Check Point 5 - Perform further corrections and begin qualitative testing of finished T-PaD Fire.

(The above dates are subject to change and we will also be working on trying to make a additional Android application that utilizes the T-PaD Fire.)

Preliminary Description of the evaluation results:

Qualitative evaluation techniques: Subjective feedback from independent users.

The finished prototype performance will be evaluated by testing the performance using independent user feedback and comparing it with intended results.

To elaborate; our aim is to induce an experience of different levels of  friction on the T-PaD surface and we would ask the user for feedback on what he/she experienced when using the surface.

Sketch for the Prototype:

(Still waiting on components so heres a reference of how things should resemble - will repost our own results once the components arrive.)

The following pictures are only an illustration to give an idea of how the completed parts would appear:

Development schedule for the prototype is held until the components arrive.
