HandsUp!
Home Page:
Here is the home page, it has a drop down menu with all the modes, a begin button, an exit button and an options page.
Options Page:
In the options page, you can select whether or not the camera is displayed on screen on startup and can change the location to where the counts are saved.
HandsUp!:
Our first mode is counting the number of hands that are raised in a frame.
For example, a teacher could ask students to raise their hands if they like dogs, and the students would answer accordingly.
Cards Raised:
The second mode is to count the cards that are being held up by students.
The teacher can select the correct answer by ticking the box. This will reflect in the saved answers file.
Once the students are holding up their cards, the teacher has the option to freeze the frame and counts by pressing the space bar, this holds the counts in place to give the teacher ample time to save the current counts to a text file in the selected location if they want to.
After saving it, the teacher can press space bar again to unfreeze the camera and move to the next question.
TableTop Mode:
The third mode is the tabletop mode, this is intended for users with limited mobility as it allows students to interact with card counting without raising the cards.
Users simply need to move their hands near the card in order for it to appear in the counts as seen in the images above.
Cumulative Card Counting:
This is intended for classes that cannot fit the entire room in one frame or for groups of students that answer at varied times.
The teacher can hit the space bar to freeze the frame and hold the counts of the first set of students.
They can then hit the space bar again to unfreeze the frame and ask the next set of students to hold their cards up.
Card counts are accumulated and not erased upon unfreezing in this mode. Once the teacher is satisfied with the number of answers they can save the answers and press the enter key to reset the counter before moving to the next question.
Viewing Saved Files:
To view the saved files, open the location in which you selected earlier and find the text file.
The file contains the timestamp of the question, the counts and the correct answer (if specified).

Privacy Policy
Last updated March 27, 2025
This Privacy Notice for HandsUp ('we', 'us', or 'our') describes how and why we might access, collect, store, use and/or share ('process') your personal information when you use our services ('Services'), including when you:
- Download and use our mobile application (HandsUP)
- Use HandsUp. An application which uses realtime, offline, AI video inference to help improve the quality and engagement of teacher's classroom activities.
Questions or concerns? Reading this Privacy Policy will help you understand your privacy rights and choices. We are responsible for making decisions about how your personal information is processed. If you do not agree with our policies, please do not use our Services. If you have any more questions, please do not hesitate to contact us at michael.kersh.23@ucl.ac.uk
1 - What Information do we collect?
We do not collect any personal information. The HandsUp app is a 100% offline based solution to improving classroom based learning, and does not communicate with any external servers, nor does it receive any information from external servers. As a result we also do not process sensitive information. Our app utilises AI based solutions in the form of video inference, and takes real time camera input to draw inference from, and determine the colours of cards. HandsUp does not process the faces or indentities of anyone in the frame, and will not store or send this information to any external servers.
2 - How do we process your information?
Any information you provide to the app will stay on your machine locally. HandsUp is a fully offline based app, and will not send any information you provide to the app.
3 - When and with whom do we share your personal information
HandsUp is a fully offline based Windows application and does not in any way communicate with external servers. HandsUp does not store or share your personal information with anyone, and only stores any information you provide it directly on your machine.
4 - Do we offer Artificial Intelligence-based products?
As part of our services, we offer features and tools powered by artificial intelligence, machine learning, or similar technologies (collectively, 'AI Products'). These tools are designed to enhance your experience and provide you with innovative solutions. The terms in this Privacy Policy govern your use of the AI Products within our Services.
Our AI Products are designed for the following functions:
- Real-time video analysis
How we process your data using AI:
Any personal information which is processed using our AI Products is not stored in any way on your local machine, or on any servers. HandsUp is a fully offline based application and will not send any information it stores to any servers. It does not store faces or identities of anyone. This ensures high security and safeguards your personal information throughout the process.
5 - How long do we keep your information?
HandsUp does not store any of your personal information, and as a result we do not keep it for any amount of time. You are permitted to save results of the application to a local file, and this is saved on your local machine, and nowhere else, for as long as you deem necessary. This information is not sent anywhere else.
6 - How do we keep your information safe?
HandsUp is a fully offline application, and therefore any information you provide HandsUp with is stored only locally, and is not sent anywhere else on the internet. However despite our safeguards and efforts to secure your informatiom, no information storage technology can be guaranteed to be 100% secure, so we cannot promise or guarantee that hackers, cybercriminals or other unauthorised third parties will not be able to improperly collect, access, steal or modify your information.
7 - What are you privacy rights?
In some regions, such as the UK, you have certain rights under applicable data protection laws. These may include the right (i) to request access to obtain a copy of your personal information, (ii) to request rectification or erasure, (iii) to restrict the processing of your personal information, (iv) if applicable, to data portability, and (v) not to be subject to automated decision-making. In certain circumstances, you may also have the right to object to the processing of your personal information. You can make such a request by contacting us by using the contact details provided in the section "How can you contact us about this policy".
We will consider and act upon any request in accordance with applicable data protection laws.
If you are located in the EEA or UK and you believe we are unlawfully processing your personal information, you also have the right to complain to your Member State data protection authority or UK data protection authority.
If you have any questions or comments about your privacy rights, you may email us at michael.kersh.23@ucl.ac.uk
8 - How can you contact us about this policy
If you have any questions, comments or concerns abot this policy, you may email us at michael.kersh.23@ucl.ac.uk.
