Interested to work on the application to measure sensor data and various parameters

[Venkata Naga Kailash Anantha]

Hello sir,

I am Kailash from India. I am doing my post graduation in CS from IIT Bombay.

I am currently working on android platform to create a reliable authentication model for the users using Android phones. I am having a fair knowledge on using the different kind of sensors available in the device and processing the data collected using them.

As you have mentioned the app is having two parts :

1. Collecting sensor data
2. Processing the collected data and show some useful analysis in the form of graphs.

We can try to provide as much flexibility as possible for the teacher/researcher by providing him/her with the choice of the data to be plotted and the way he/she wants it to be represented.

Also, I feel that the app needs to be energy efficient. It helps a lot when the researcher needs to collect data for longer durations in a remote area where charging his/her device may be difficult.

I am working on the project and will come up with a more clear proposal.

Hi Kailash,

 

We can try to provide as much flexibility as possible for the teacher/researcher by providing him/her with the choice of the data to be plotted and the way he/she wants it to be represented.

Also, I feel that the app needs to be energy efficient. It helps a lot when the researcher needs to collect data for longer durations in a remote area where charging his/her device may be difficult.

I am working on the project and will come up with a more clear proposal.

Great, you seem to have understood the project well. Making the app energy efficient is required, it should not drain the battery in 30 mins while using the application.  This could be done by making the app event driven and monitoring only required sensor's output at a time.

So, as part of this energy efficient designing, do we need to make the device run in a very low power consumption mode? What I feel is usually data collection kind of tasks will not be done on personal devices but on some specially allotted tablets/phones. So, I think we can take this into consideration for designing the app.

I would like to propose different versions of the app (we will take the user feedback and change the plan accordingly):

• Version 1 (Our primary Target) :  providing a user interface to choose the sensors to work with and have another interface for the graphs.
  
• Veresion 2 (Depends on the user response) : If the data collection taks is going to involve a very long duration of experiment and need many sensors data, we can use multiple devices.So, we can provide a mechanism which enables multiple devices to communicate wand share the work so that the duration for which they run will be increased

Now coming to the version 1 , the places where I feel the optimisation can be done are as follows :

• Hardware level optimisation(like reducing the brightness of the screen, using less power consuming interfaces, turning off unnecessary sensors and other hardware etc)
• Software level optimisation (by using energy efficient operations, minise the utilization of hardware unnecessarily, reducing the time our app interacts with the memory units unnecessarily etc)

The reason why I am discussing about the energy efficiency more is, from my personal experience I have seen many people rejecting applications that use more energy and computation power of their devices.

The features of the application will include the following :

• An interface to choose the sensors that will be activated to collect data.
• The type of graph they want.
• The frequency(time interval) at which the data will be collected by the sensors.
• Whether the graph will be static(the graph will not be updated with the new data) or dynamic(graph will be updated with the new data) and the time interval for which they want the graph to be plotted.
• Storing the generated graphs.

PS : Please tell which features you are expecting as part of the GSoC? Did I miss any features that you wanted to include?

I think the second version of the app will take more time as it needs to deal with a network architecture.

Please provide your feedback and guide me to think in the right direction if I am not.

Thanking you,

Kailash

Hi Venkata,

I would suggest you to just concentrate on one version. We are not keen on collating sensor data from multiple devices, however visualising data from two or more sensors together is something that we would be interested in.

 

• An interface to choose the sensors that will be activated to collect data.

• The type of graph they want.

• The frequency(time interval) at which the data will be collected by the sensors.

• Whether the graph will be static(the graph will not be updated with the new data) or dynamic(graph will be updated with the new data) and the time interval for which they want the graph to be plotted.

• Storing the generated graphs.

This looks like what we are looking for. We would be looking for more interesting visualisations in addition to a 2D graph.

Regards,

Pankaj.

Can you explain in more detail about the user base you are targeting?

[Rahul Ahuja]

For this application the users would be teachers, researchers and scientists who already how these sensors work. They would be using the app as a utility in their workplace.

Do you expect the graphs to show future predictions of the sensor behavior? Or just plot the collected data till then?

While doing the experiment, we will display only the collected. But later while visulising the same data for analysis, we can show some predictions. Is that feature needed?

I am preparing a Design document and will send you in 2 days or so, as I am currently having my R & D work.Sorry for the late reply.

Hi Venkata

No we do not need capabilities for future predictions, just showing current sensor data is the requirement.
