Brain-computer interface (BCI) allows direct communication between the brain and an external device. It differs from other interfaces in allowing bidirectional information exchange. The history of BCIs began with Hans Berger's discovery of electrical brain activity in the 1920s. Testing on monkeys in the 1970s showed voluntary control of neuron firing, while the first prototype for a human was implanted in 1978. BCIs can work through electroencephalography (EEG) or direct implantation. Current applications include assisting disabled individuals, but challenges remain around signal accuracy, information transfer rates, and cost.

Current BCIs have information transfer rates up to 25 bits per minute. BCIs have applications in healthcare, education, gaming and the military. While promising, they also face challenges regarding accuracy, invasiveness and global access.
BRAIN COMPUTER INTERFACE
1. A brain-computer interface (BCI) allows direct communication between the brain and external devices, helping people with motor impairments and providing new functionality.
2. BCI can be invasive, using implants in the brain to detect high-quality signals, but these are prone to scar tissue buildup. Non-invasive BCIs use neuroimaging techniques but produce poorer signals.
3. Experiments have used EEG to detect brainwaves and allow people to type or control devices through thought. As detection techniques improve, BCI could provide more alternatives for people to interact with their environment.

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdf
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:

Climate Impact of Software Testing at Nordic Testing Days
My slides at Nordic Testing Days 6.6.2024
Climate impact / sustainability of software testing discussed on the talk. ICT and testing must carry their part of global responsibility to help with the climat warming. We can minimize the carbon footprint but we can also have a carbon handprint, a positive impact on the climate. Quality characteristics can be added with sustainability, and then measured continuously. Test environments can be used less, and in smaller scale and on demand. Test techniques can be used in optimizing or minimizing number of tests. Test automation can be used to speed up testing.

Epistemic Interaction - tuning interfaces to provide information for AI support
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.

BCI(Brain Computer Interface) project
- 2. Contents Introduction History On what it works(Neurons) ! How it works? Electroencephalography Types of BCI => In Detail Future scope Problems and limitations Reference Want to know more ? Poster
- 3. What is Brain Computer Interface? BCI is a direct communication pathway between an enhanced or wired brain and an external device. BCI differs from neuromodulation in that it allows for bidirectional information flow.
- 4. It is also known as Neural-control interface (NCI) Mind-machine interface (MMI) Direct neural interface (DNI) Brain–machine interface (BMI)
- 5. History of BCI The history of brain–computer interfaces (BCIs) starts with Hans Berger's discovery of the electrical activity of the human brain. In the 1970s it was tested on monkey to voluntarily control the firing rates of individual and multiple neurons in the primary motor cortex. Testing on humans:- Dobelle's first prototype was implanted into "Jerry", a man blinded in adulthood, in 1978.
- 6. Neurons A neuron (also called nerve cell) is a cell that carries electrical impulses.
- 7. BCI Setup
- 10. Electroencephalography (EEG) Electroencephalography (EEG) is an electrophysiological monitoring method to record electrical activity of the brain.
- 12. Invasive BCI Implanted directly into the grey matter Produce the highest quality of signal Scar-tissue build-up Targeted for people with paralysis
- 13. Partially Invasive BCI BCI devices are implanted inside the skull Produce better resolution signals Lower risk of forming scar- tissue
- 14. Non-Invasive BCI Easy to wear Produce poor signal resolution It has less risk than above two methods
- 15. Possible uses of BCI Provide disabled people with communication, environment control, and movement restoration. Provide enhanced control of devices such as wheelchairs, vehicles, or assistance robots for people with disabilities. To play game with mind.
- 16. Continued..... Monitor attention in long-distance drivers or aircraft pilots, send out alert and warning for aircraft pilots. Control robots that function in dangerous or inhospitable situations (e.g., underwater or in extreme heat or cold).
- 17. Problems and Limitations Lack of sensor modality that provides safe, accurate, and robust access to brain signals. Information transformation rate is limited to 20 bits/min. Difficulty in adaptation and learning. It is very expensive.
