Brain Computer Interface allows direct communication between the brain and external devices. It reads electrical signals from the brain and translates them into a digital format. Research on BCIs started in the 1970s with basic sensors implanted in rats, mice, monkeys and humans. Today, BCIs can be invasive, partially invasive or non-invasive. Invasive BCIs are implanted directly into the brain to provide high quality signals, while non-invasive BCIs like EEGs record electrical activity from the scalp. BCIs have applications in medicine, military technology, and assisting people with disabilities.
It consists of all details about BCI which are necessary, I sorted from net and implemented in PPT. For abstract U can mail me koushik.veldanda@gmail.com
(It is not my own talent,it is a collaboration of 4 to 5 PPT's , wiki and other sites.
But simply awesome )
This presentation is given in (2015) . As the power of modern computers grows alongside our understanding of the human brain, we move ever closer to making some pretty spectacular science fiction into reality.
BCI or DNI is a direct communication pathway between an enhanced or wired brain and an external device. DNIs are often directed at researching, mapping, assisting, augmenting, or repairing human cognitive or sensory-motor functions.
Computer-brain interface is a mainstay of science fiction, and devices are available today to use our brainwaves as a computer input. But is it practical? How far away is it? Will "Big Brother" read our thoughts and hack our brains?
In this class, we will dive into the future of thought as input for wearable devices with real-world examples and code. Demonstrations will be shown using the Emotiv EPOC headset, a revolutionary high resolution, neuro-signal acquisition and processing wireless neuroheadset that uses a set of sensors to tune into electric signals produced by the brain to detect thoughts, feelings and expressions.
You will see the EEG neuroheadset and computer interface with examples of interfacing with desktop, mobile and wearable apps. We will dive into the roots of the technology, showing code and examples along with big pictures of the technology. You will walk away with an understanding of how this still evolving and largely unknown technology really works, how it can be used, as well as longer-term implications.

System Architecture for Brain-Computer Interface based on Machine Learning an...ShahanawajAhamad1
Brain functions are required to be read for curing
neurological illness. Brain-Computer Interface (BCI) connects
the brain to the digital world for brain signals receiving,
recording, processing, and comprehending. With a BrainComputer Interface (BCI), the information from the user’s brain
is fed into actuation devices, which then carry out the actions
programmed into them. The Internet of Things (IoT) has made it
possible to connect a wide range of everyday devices.
Asynchronous BCIs can benefit from an improved system
architecture proposed in this paper. Individuals with severe
motor impairments will particularly get benefit from this feature.
Control commands were translated using a rule-based
translation algorithm in traditional BCI systems, which relied
only on EEG recordings of brain signals. Examining BCI
technology’s various and cross-disciplinary applications, this
argument produces speculative conclusions about how BCI
instruments combined with machine learning algorithms could
affect the forthcoming procedures and practices. Compressive
sensing and neural networks are used to compress and
reconstruct ECoG data presented in this article. The neural
networks are used to combine the classifier outputs adaptively
based on the feedback. A stochastic gradient descent solver is
employed to generate a multi-layer perceptron regressor. An
example network is shown to take a 50% compression ratio and
89% reconstruction accuracy after training with real-world,
medium-sized datasets as shown in this paper
in this ppt i tried to help people understand what is bci how its work and how it can be implemented in our life and its potential to change our perspective of looking world.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.
