DARPA's Augmented Cognition Program

The Defense Advanced Research Projects Agency (DARPA) has been one of the primary funding agencies for augmented cognition investigators. A major focus of DARPA's augmented cognition program (AugCog) has been developing more robust tools for monitoring cognitive state and integrating them with computer systems. The program envisions "order of magnitude increases in available, net thinking power resulting from linked human-machine dyads [that] will provide such clear informational superiority that few rational individuals or organizations would challenge under the consequences of mortality."

The program began in 2001, and has since be renamed to Improving Warfighter Information Intake Under Stress Program. By leveraging such tools, the program seeks to provide warfighters with enhanced cognitive abilities, especially under complex or stressful war conditions. As of 2002, the program vision is divided into four phases:

• Phase 1: Real-time cognitive state detection
• Phase 2: Real-time cognitive state manipulation
• Phase 3: Autonomous cognitive state manipulation
• Phase 4: Operation demonstration and transition

Proof of concept was carried out in two phases: near real time monitoring of the user's cognitive activity, and subsequent manipulation of the user's cognitive state.

Augmented Cognition International (ACI) Society

The Augmented Cognition International (ACI) Society held its first conference in July 2005. At the society's first conference, attendees from a diverse background including academia, government, and industry came together to create an agenda for future research. The agenda focused on near-, medium-, and long-term research and development goals in key augmented cognition science and technology areas. The International Conference on Human Computer Interaction, where the society first established itself, continues to host the society's activities.

Translation engines

Thad Starner, and the American Sign Language (ASL) Research Group at Georgia Tech, have been researching systems for the recognition of ASL. Telesign, a one-way translation system from ASL to English, was shown to have a 94% accuracy rate on a vocabulary with 141 signs.

Augmentation Factor

Ron Fulbright proposed the augmentation factor (A⁺), as a measure of the degree a human is cognitively enhanced by working in collaborative partnership with an artificial cognitive system (cog). If W_H is the cognitive work performed by the human in a human-machine dyad, and W_C is the cognitive work done by the cog then A⁺ = W_C/W_H. In situations where a human is working alone without assistance, then W_C = 0 resulting in A⁺ = 0 meaning the human is not cognitively augmented at all. In situations where the human does more cognitive work than the cog, A⁺ < 1. In situations where the cog does more cognitive work than the human, A⁺ > 1. As cognitive systems continue to advance, A⁺ will increase. In situations where a cog performs all cognitive work without the assistance of a human, then W_H = 0 resulting in A⁺ = <undefined> meaning attempting to calculate the augmentation factor is nonsensical since there is no human involved to be augmented.

Human/Cog Ensembles

Whereas DARPA's AugCog program focuses on human/machine dyads, it is possible for there to be more than one human and more than one artificial element involved. Human/Cog Ensembles involve one or more humans working with one or more cognitive systems (cogs). In a human/cog ensemble, the total amount of cognitive work performed by the ensemble, W*, is the sum of the cognitive work performed by each of the N humans in the ensemble plus the sum of the cognitive work performed by each of the M cognitive systems in the ensemble:

W* = ${\displaystyle \sum _{k=1}^N}$W^k_H + ${\displaystyle \sum _{k=1}^M}$W^k_C

Controversy

Privacy concerns

The increasing sophistication of brain-reading technologies has led many to investigate their potential applications for lie detection. Legally required brain scans arguably violate "the guarantee against self-incrimination" because they differ from acceptable forms of bodily evidence, such as fingerprints or blood samples, in an important way: they are not simply physical, hard evidence, but evidence that is intimately linked to the defendant's mind. Under US law, brain-scanning technologies might also raise implications for the Fourth Amendment, calling into question whether they constitute an unreasonable search and seizure.

Human augmentation

Many of the same arguments in the debate around human enhancement can be analogized to augmented cognition. Economic inequality, for instance, may serve to exacerbate societal advantages and disadvantages due to the limited availability of such technologies.

Fearing the potential applications of devices like Google Glass, certain gambling establishments (such as Caesar's Palace in Las Vegas) banned its use even before it was commercially available.
