Reprioritizing the Relationship Between HCI Research and Practice: Bubble-Up ...colin gray
There has been an ongoing conversation about the role and relationship of theory and practice in the HCI community. This paper explores this relationship privileging a practice perspective through a tentative model, which describes a “bubble-up” of ideas from practice to inform research and theory development, and an accompanying “trickle-down” of theory into practice. Interviews were conducted with interaction designers, which included a description of their use of design methods in practice, and their knowledge and use of two common design methods—affinity diagramming and the concept of affordance. Based on these interviews, potential relationships between theory and practice are explored through this model. Disseminating agents already common in HCI practice are addressed as possible mechanisms for the research community to understand practice more completely. Opportunities for future research, based on the use of the tentative model in a generative way, are considered.

It describes how BCIs work by detecting brain signals through electrodes, analyzing the signals to correlate them with specific commands, and using those commands to control devices. The document outlines the history of BCIs from early animal experiments to current human applications. It also discusses limitations and future directions, such as using light-based imaging instead of electrodes to improve BCIs.
The document describes the Brain Gate system, a brain-computer interface that allows paralyzed individuals to control external devices with their thoughts. The Brain Gate system works by implanting an array of electrodes on the motor cortex that detects neural signals related to intended movement. These signals are transmitted to a computer via wires and translated into commands to operate a cursor or prosthetic. The system was developed in 2003 and has helped paralyzed individuals perform tasks like using email and playing simple games. While promising, the Brain Gate system has limitations like expense, time needed for processing, and difficulty adapting. Future improvements could make the technology more accurate and useful for individuals with paralysis or disabilities.
BrainGate is a neuroprosthetic device that uses a sensor implanted in the brain to monitor brain activity and convert those signals into computer commands. It was developed in 2003 to help people who have lost control of limbs, like those with ALS or spinal cord injuries, regain independence. The implant consists of a microelectrode array and connector that detects neural signals in the motor cortex when a user thinks of moving and translates that into mouse cursor movements on a computer screen.

Brain-computer interface (BCI) is a fast-growing emergent technology, in which researchers aim to build a direct channel between the human brain and the computer.
A Brain Computer Interface (BCI) is a collaboration in which a brain accepts and controls a mechanical device as a natural part of its representation of the body.
Computer-brain interfaces are designed to restore sensory function, transmit sensory information to the brain, or stimulate the brain through artificially generated electrical signals.
A brain-computer interface is a direct communication pathway between the brain and an external device. BCIs can be invasive, implanted inside the brain, or non-invasive, using external sensors like EEG to read brain signals. The brain's neurons communicate via electric signals that an EEG can detect on the scalp. Researchers have used EEG-based BCIs to allow communication between two human brains. While BCIs could help treat disabilities and allow new forms of control, challenges remain in interpreting complex brain signals and developing portable, non-invasive devices.
Brain-computer interfaces (BCIs) allow direct communication between the brain and external devices. There are invasive BCIs that are implanted in the brain, partially invasive BCIs implanted in the skull, and non-invasive BCIs that record brain activity from the scalp using electroencephalography (EEG). EEG measures voltage differences between neurons which are amplified, filtered, and interpreted by a computer program. BCIs have applications in areas like criminal investigations, home automation, airplane control, and helping people with disabilities communicate. While BCIs open new possibilities, challenges remain in interpreting complex brain signals and developing portable equipment.

Paper Title
Particle Swarm Optimization–Long Short-Term Memory based Channel Estimation with Hybrid Beam Forming Power Transfer in WSN-IoT Applications
Authors
Reginald Jude Sixtus J and Tamilarasi Muthu, Puducherry Technological University, India
Abstract
Non-Orthogonal Multiple Access (NOMA) helps to overcome various difficulties in future technology wireless communications. NOMA, when utilized with millimeter wave multiple-input multiple-output (MIMO) systems, channel estimation becomes extremely difficult. For reaping the benefits of the NOMA and mm-Wave combination, effective channel estimation is required. In this paper, we propose an enhanced particle swarm optimization based long short-term memory estimator network (PSOLSTMEstNet), which is a neural network model that can be employed to forecast the bandwidth required in the mm-Wave MIMO network. The prime advantage of the LSTM is that it has the capability of dynamically adapting to the functioning pattern of fluctuating channel state. The LSTM stage with adaptive coding and modulation enhances the BER.PSO algorithm is employed to optimize input weights of LSTM network. The modified algorithm splits the power by channel condition of every single user. Participants will be first sorted into distinct groups depending upon respective channel conditions, using a hybrid beamforming approach. The network characteristics are fine-estimated using PSO-LSTMEstNet after a rough approximation of channels parameters derived from the received data.

2. ABSTRACT:
• The human brain is of the size of a deflated volleyball
which weighs about 3 pounds. We live at a time when the
disabled are on the leading edge of a broader societal
trend toward the use of assistive technology known as
Brain Computer Interface.
• Brain-computer interface (BCI) is a collaboration between
a brain and a device that enables signals from the brain to
direct some external activity, such as control of a cursor or
a prosthetic limb.
3. • The interface enables a direct communications
pathway between the brain and the object to be
controlled with the advent of miniature wireless
tech, electronic gadgets have stepped up the invasion
of the body through innovative techniques.
4. WHAT IS BRAIN COMPUTER INTERFACE
• Brain Computer Interface is a direct technological
interface between a brain & a computer system not
requires a motor output from the user.
• It is also known as Direct Neural Interface (DNI) &
Brain – Machine Interface (BMI).
• Brain-computer interface is an electrode chip which
can be implemented in the brain through
surgical procedure.
5. • When it is implemented in brain
the electrical signal exchanged by
neurons within the brain are sent to the
computer and then the computer is
controlled by person.
6. PRINCIPLE OF BCI :
• This technology is based on to sense, transmit, analyze
and apply the language of neurons.
• It consist of a sensor that is implanted in the motor cortex
of the brain and a device that analyses brain signals.
• The signals generated by brain are interpreted and
translated into cursor movement on computer screen to
control the computer.
• It consists of a silicon array about the size of an Aspirin
tablet that contains about 100 electrodes each thinner
than a human hair.
8. OBJECTIVES OF BCI
• The goal of the Brain-Computer Interface is to develop a
fast and reliable connection between the brain of a
severely disabled person and a personal computer .
• The ‘Brain Gate’ device can provide paralysed or motor-
impaired patients a mode of communication through the
translation of thought into direct computer control.
10. BCI VERSUS NEUROPROSTHETICS
• Neuroprosthetics typically connect the nervous system
to a device, whereas BCIs usually connect the nervous
system with a computer system.
• Practical neuroprosthetics can be linked to any part of
the nervous system for example, peripheral nerves.
• While the term "BCI" usually designates a narrower
class of systems which interface with the central
nervous system.
11. TYPES OF BCI’S
• Invasive BCI :
Invasive BCIs are implanted directly into the grey matter of the brain
during neurosurgery.
• Non Invasive BCI :
Non-Invasive BCIs do not involve neurosurgery. They are just like
wearable virtual reality devices.
• Partially Invasive BCI :
Partially invasive BCI devices are implanted inside the skull but rest
outside the brain rather than within the grey matter.
12. BCI RESEARCH ON ANIMALS
• At first, rats were implanted with BCI .
• Signals recorded from the cerebral cortex of rat operate BCI to
carry out the movement.
• Researchers at the University of Pittsburgh had demonstrated on a
monkey that can feed itself with a robotic arm simply by using
signals from its brain.
13. BCI ON HUMANS
• In December 7, 2004, brain-computer interface had been clinically
tested on a human by an American biotech company Cyberkinetics.
• The first participant in these trials was a 25-year-old man who had
sustained a spinal cord injury leading to paralysis in all four limbs.
• Over a period of nine months, he took part in 57 sessions during which
the implanted Brain Gate sensor recorded activity in his motor cortex
region while he imagined moving his paralyzed limbs and then used that
imagined motion for several computer-based tasks such as, moving a
computer cursor to open e-mail, draw shapes and play simple video
games.

15. ADVANTAGES OF BCI
• This technology allows paralyzed people to control prosthetic
limbs with their mind.
• This transmit visual images to the mind of a blind person,
allowing them to see and also transmit auditory data to the
mind of a deaf person, allowing them to hear.
• This Technology allows gamers to control video games with
their minds.
• This also allows a mute person to have their thoughts
displayed and spoken by a computer.
16. DISADVANTAGES
• At present ,the biggest impediment of BCI technology is the lack of
sensor modality that provides safe, accurate, and robust access to brain
signals.
• The current technology is crude and very expensive.
• Electrodes outside of the skull can detect very few electric signals from
the brain and Information transformation rate is limited to 20 bits/min.
• Electrodes placed inside the skull create scar tissue in the brain.
17. FUTURE SCOPE
• Wireless implants In brain.
• Injectable implants.
• Brain to brain communication.
• Decode non-motor brain signals.
• Researchers of the Carleton University , Canada believe that the same
interface could form the basis of a mind-controlled password system.
18. CONCLUSION
• The results of BCI are spectacular and almost unbelievable.
• BCI can help paralyzed people to move by controlling their own electric
wheelchairs, to communicate by using e-mail and Internet-based
phone systems, and to be independent by controlling items such as
televisions and electrical appliances.
• Conclusively, BCI has proved to be a boon for paralyzed patients.
• Futurists predict that superhuman artificial intelligence won't be far
behind.
