What did we finally arrive at
Final Prototype
We created the prototype of the clock and showed time in hours and minuted on the form.
The hour's hand is shown in the inside concentric circle resembling the clock hand and the minutes hand is shown outside like a continuous data visualisation.
The colour of the hour LED changes change according to the hour of the day.
The Web-camera is connected on the right side of the door and the machine is trained to identify the person entering
The Clock is placed in a position such that the entire class can see it.
Breadboard, Arduino are installed at the back of the clock and it is connected to the magnetic reed switch at the fixed end of the door.
Following video describes the working of the final model:
How will we sell our product?
Business Plan
Target audience: The product will be sold to institutions like schools, colleges, coaching classes, corporates and other places which requires students/ adults to reach on time. Tie-ups with interior designers and architects will also help in increasing the sales of the Tick-Tok system.
USP: The USP of this clock is that it solves or tries solve the age old problem of employees and students coming late for their work and classes respectively. The traditional approach of scolding, making the student/ employee stand out of the class/ office or simply not giving attendance has not really helped in solving the problem.
No. Of Units Produced - 20/ month
Promotion: Presentations and demonstrations to the institutions and authorities. Advertisements on social medias like Instagram, Facebook, LinkedIn, Twitter. Conferences concerning education systems and interior designing of classrooms can also be a good platform for promotion.

We also think about the future
Future Scope
The product is expected to buzz in different intensities depending upon how many times a student has been late to the class in a month.
To make sure that the clock does not buzz when the breaks are postponed or preponed by the faculty, there will be a buzzer placed near the door so that the faculty can press it ones he/she leaves the class for the break. The clock will automatically set a timer for 15 mins/ 45mins (depending on the time of the break) after which it will resume buzzing for those who enter the class late.
For this product to be more efficient, the face recognition will recognise who is entering the class and will differentiate between a peon, faculty and a student to buzz accordingly.
For this prototype, we have included machine learning. However, system has to be machine trained again everytime it is re-started. We will incorporate a permament learning using .json extension in which the training has to be done only once.
We successfully achieved recording the wi-fi signal data on ThingSpeak. We will push the face recognition of ThingSpeak in the future model.
