OpenCapSense FYP Finalized Application Idea

OpenCapSense FYP Application


DJ Table


Objective


After second thought, we decided to amend our project idea to apply the techonology into doing something interesting. We thought of applications in different areas, for the youngs and the elderly, used indoor and outdoor, for individuals and groups of people… Our only concern is that the idea can make use of the strengths of the opencap sense kit to a greatest extent.


We finally came up with the idea of a DJ table, which is roughly the same by means of function when compared with those you can find from the market. But our idea differentiates itself from all the other similar products in terms of controlling method. We are combining the capacitance sensing property of the kit with the various music effect a DJ table can create - instead of simply adjusting the knobs, we wish to present a sening table that allows users to do air-float gestures to trigger changes in parameters such as the adjustment in volumes, fast-forwarding and echo effect.


What is special in our product is that it enables effects to come with the natural body movements of humans when they listen to music, like the unconscious making of beats and the natural dancing-like movements. We believe that our OpencapSense kit application can bring the user experience of the DJ table to a higher level, and create more fun for the parties!

Details of the project


Since the OpenCapSense kit has its own limitations, we can at most connect to eight sensors at one time. It thus may not be that ideal if we assign one sensor to be responsible for one single function. In order to allow more possibilities of functions and gestures, we tried to correlate the sensors such that the functions are triggered by a series of sensing activities instead of the change in one single sensor. We came up with a number of prototypes as shown below:


Prototype A



Prototype B



Prototype C



Prototype D


Prototype A shows the simpliest assignment of sensors - each one is responsible for one single action.


Prototype B, C and D allows switching of controlling parameters with gestures (more than one sensors carrying out multiple sensing at one time to detect a particular set of body movements).


After a series of testing, we finally decided to adopt prototype D for our sensor assignment as we believed that such an arrangement can provide the users with the most freedom in gesturing.

We haven’t finalized the functions of our DJ table yet, but at this stage it will include some basic features such as volume control, play-forward/play-back function and fade-in/fade-out effect.
