Gaming and Entertainment
- gaming- good application of BCI + lack of liability
- Some examples include:
- Cheung+Rao (2012)- subject control 2-D motion w/ joystick and hand motor imagery using EEG
- controlled up-down motion of cursor using imagery, joystick for left-right motion
- Brainball (Hjelm and Browall 2000): control relaxation level by alpha rhythms
- MindGame (Finke 2009): P300- moves a character across a 3D board
- Cheung+Rao (2012)- subject control 2-D motion w/ joystick and hand motor imagery using EEG
More Cool Games! :)
- other gaming applications use SSVEP, or motor imagery and EEG-based virtual navigation
- More examples:
- BCI-controlled pinball machine (Tangermann 2009): paddle controlled by 2-class BCI based on imagery (left and right hand motor!)
- Tetris (Blankertz 2010): left or right-hand motor imagery to make tetris go left/right, mental rotation to rotate, foot motor imagery to drop!
Brain-Controlled Art
- fNIR-based sketch drawing program (Mappus, Jackson 2009)
- perhaps can use the user's brain signal when they're responding to the art to change some elements of the art
- "The Ascent" by Yehuda Duenyas- wears 3-D flying harness and a dry electrode headset - allows performers to ascend based on brain signals
- done by detecting alpha and theta band oscillations in EEG
Ethics of BCI
Balancing Risks vs Benefits
- care about damage or infection of invasive BCIs
- Some questions include:
- What are the potential side effects?
- What are the patient's expectations?
- What effect does it have on family?
- Does the increase performance of an invasive BCI compared to non-invasive justify the risk associated with it?
Informed Consent
- the definition of informed consent includes:
- the risks + benefits associated with BCI technology in comparison to the alternative methods
- information being extracted from the brain
- consequences of extracting this information: could it lead to embarrassment or legal consequences?
More Informed Consent
-
some complications of BCI use might include:
- in the case of children, is it enough to get consent from their parents?
- if there's a locked-in patient, who gets to give consent then?
- can consent be obtained from patients suffering from cognitive deficits that prevent them from fully understanding the benefits vs risks?
Abuse of BCI Technology
- some immoral usage of BCI technology might include:
- Mind reading or "brain tapping": we are able to intercept, record, or exploit a person's thoughts, reflections, adn beliefs using BCI technology. This might be used by criminals, terrorists, corporations, or spy agencies- not to mention law enforcement and military entities
- Coercion or "mind control": BCI can be hijacked or used to force someone to do something against their own will
More Abuse of BCI
- some immoral usage of BCI technology might include:
- Memory Manipulation: BCI that can stimulate the brain can also erase memories or write in false memories, or even "brainwashing"
- Viruses: a computer virus can be tapped into the machine, and it will lad to cognitive impairment or manipulation
- BCI can also be tampered with to bias an outcome. "lie detection" can be manipulated to align an outcome.
- need strong security measures as our responsibilities with this enormous power
BCI Security and Privacy
- Institutional Review Board (IRB) checks for guidelines to ethical human subjects research.
- What neural data is being stored? Could the data reveal something that breaches privacy? Will the data be stored and for how long, and why?
- Activities against BCI security and privacy should be illegal.
- However, there are a lot of rules that are not yet set in stone.
Legal Issues
- lawmakers will need to determine which BCI activities are legal or not.
- courts will have to decide the consequences of it
- what if the BCI machine did something illegal using the user's subconscious, then is the user responsible for it?
- BCI users might need to sign a waiver, much like driving a car. However, it's much easier to tell when it's the car vs the driver's fault than it is for BCI and its user.
Moral and Social Justice Issues
- Moral dilemmas arise for something such as cochlear implants. Some deaf people don't think deafness is a disability. So should a deaf child receive this implant?
- Also, evolution sculpted the brain to control our bodies with physical environment. So how will this escape from limitations imposed by our bodies change evolution?
- Social justice problems will occur such as if the rich gives their children some implants to enhance physical or mental abilities
More on Moral and Social Justice
- Potential Solution: government subsidize basic types of BCI for those who can't afford them
- Parents will also be faced with the decision that should they allow their child to be involved with BCI? Then will they leave their child at an advantage vs disadvantage?
- society might be split into the "haves" and the "have-nots", and how will social institutions such as schools or athletes or the Olympics handle that?
