(16) High-speed, Non-deformation Catching with High-speed Vision and Proximity Feedback... - 0 views

  •  
    "We demonstrated the high-speed, non-deformation catching of a marshmallow. The marshmallow is a very soft object which is difficult to grasp without deforming its surface. For the catching, we developed a 1ms sensor fusion system with the high-speed active vision sensor and the high-speed, high-precision proximity sensor. Generally, a tactile feedback is used to grasp various kinds of soft objects without deforming. However, the robot hand tends to deform the object surface with only tactile feedback. By slowing the grasping speed, the deformation becomes smaller. However, grasping time becomes longer. The 1ms sensor fusion system enabled seamless, high-sensitive sensing from non-contact to contact state. The robot hand could control fingertip position dynamically and precisely based on the visual and the proximity feedback. By the proximity feedback, contact to the object was detected before deforming its surface, and grasping motion is stopped. The robot hand could catch the marshmallow even if the position and posture of it were different. http://www.k2.t.u-tokyo.ac.jp/fusion/... SHOW MORE "

    "With each interaction, Alexa is training to hear better, to interpret more precisely, to trigger actions that map to the user's commands more accurately, and to build a more complete model of their preferences, habits and desires. What is required to make this possible? Put simply: each small moment of convenience - be it answering a question, turning on a light, or playing a song - requires a vast planetary network, fueled by the extraction of non-renewable materials, labor, and data. The scale of resources required is many magnitudes greater than the energy and labor it would take a human to operate a household appliance or flick a switch. A full accounting for these costs is almost impossible, but it is increasingly important that we grasp the scale and scope if we are to understand and govern the technical infrastructures that thread through our lives. III The Salar, the world's largest flat surface, is located in southwest Bolivia at an altitude of 3,656 meters above sea level. It is a high plateau, covered by a few meters of salt crust which are exceptionally rich in lithium, containing 50% to 70% of the world's lithium reserves. 4 The Salar, alongside the neighboring Atacama regions in Chile and Argentina, are major sites for lithium extraction. This soft, silvery metal is currently used to power mobile connected devices, as a crucial material used for the production of lithium-Ion batteries. It is known as 'grey gold.' Smartphone batteries, for example, usually have less than eight grams of this material. 5 Each Tesla car needs approximately seven kilograms of lithium for its battery pack. 6 All these batteries have a limited lifespan, and once consumed they are thrown away as waste. Amazon reminds users that they cannot open up and repair their Echo, because this will void the warranty. The Amazon Echo is wall-powered, and also has a mobile battery base. This also has a limited lifespan and then must be thrown away as waste. According to the Ay

When models are everywhere - O'Reilly - 0 views

    You probably interact with fifty to a hundred machine learning products every day, from your social media feeds and YouTube recommendations to your email spam filter and the updates that the New York Times, CNN, or Fox News decide to push, not to mention the hidden models that place ads on the websites you visit, and that redesign your 'experience' on the fly. Not all models are created equal, however: they operate on different principles, and impact us as individuals and communities in different ways. They differ fundamentally from each other along dimensions such as alignment of incentives between stakeholders, "creep factor", and the nature of how their feedback loops ope !L

Gamification has a dark side - 0 views

  • Gamification is the application of game elements into nongame spaces. It is the permeation of ideas and values from the sphere of play and leisure to other social spaces. It’s premised on a seductive idea: if you layer elements of games, such as rules, feedback systems, rewards and videogame-like user interfaces over reality, it will make any activity motivating, fair and (potentially) fun. ‘We are starving and games are feeding us,’ writes Jane McGonigal in Reality Is Broken (2011). ‘What if we decided to use everything we know about game design to fix what’s wrong with reality?’
  • But gamification’s trapping of total fun masks that we have very little control over the games we are made to play – and hides the fact that these games are not games at all. Gamified systems are tools, not toys. They can teach complex topics, engage us with otherwise difficult problems. Or they can function as subtle systems of social control.
  • The problem of the gamified workplace goes beyond micromanagement. The business ethicist Tae Wan Kim at Carnegie Mellon University in Pittsburgh warns that gamified systems have the potential to complicate and subvert ethical reasoning. He cites the example of a drowning child. If you save the child, motivated by empathy, sympathy or goodwill – that’s a morally good act. But say you gamify the situation. Say you earn points for saving drowning children. ‘Your gamified act is ethically unworthy,’ he explained to me in an email. Providing extrinsic gamified motivators, even if they work as intended, deprive us of the option to live worthy lives, Kim argues. ‘The workplace is a sacred space where we develop ourselves and help others,’ he notes. ‘Gamified workers have difficulty seeing what contributions they really make.’

  • The 20th-century French philosopher Michel Foucault would have said that these are technologies of power. Today, the interface designer and game scholar Sebastian Deterding says that this kind of gamification expresses a modernist view of a world with top-down managerial control. But the concept is flawed. Gamification promises easy, centralised overviews and control. ‘It’s a comforting illusion because de facto reality is not as predictable as a simulation,’ Deterding says. You can make a model of a city in SimCity that bears little resemblance to a real city. Mistaking games for reality is ultimately mistaking map for territory. No matter how well-designed, a simulation cannot account for the unforeseen.

High score, low pay: why the gig economy loves gamification | Business | The Guardian - 0 views

  • Simply defined, gamification is the use of game elements – point-scoring, levels, competition with others, measurable evidence of accomplishment, ratings and rules of play – in non-game contexts. Games deliver an instantaneous, visceral experience of success and reward, and they are increasingly used in the workplace to promote emotional engagement with the work process, to increase workers’ psychological investment in completing otherwise uninspiring tasks, and to influence, or “nudge”, workers’ behaviour.
  • According to Burawoy, production at Allied was deliberately organised by management to encourage workers to play the game. When work took the form of a game, Burawoy observed, something interesting happened: workers’ primary source of conflict was no longer with the boss. Instead, tensions were dispersed between workers (the scheduling man, the truckers, the inspectors), between operators and their machines, and between operators and their own physical limitations (their stamina, precision of movement, focus). The battle to beat the quota also transformed a monotonous, soul-crushing job into an exciting outlet for workers to exercise their creativity, speed and skill. Workers attached notions of status and prestige to their output, and the game presented them with a series of choices throughout the day, affording them a sense of relative autonomy and control. It tapped into a worker’s desire for self-determination and self-expression. Then, it directed that desire towards the production of profit for their employer.
  • Former Google “design ethicist” Tristan Harris has also described how the “pull-to-refresh” mechanism used in most social media feeds mimics the clever architecture of a slot machine: users never know when they are going to experience gratification – a dozen new likes or retweets – but they know that gratification will eventually come. This unpredictability is addictive: behavioural psychologists have long understood that gambling uses variable reinforcement schedules – unpredictable intervals of uncertainty, anticipation and feedback – to condition players into playing just one more round.

  • Gaming the game, Burawoy observed, allowed workers to assert some limited control over the labour process, and to “make out” as a result. In turn, that win had the effect of reproducing the players’ commitment to playing, and their consent to the rules of the game. When players were unsuccessful, their dissatisfaction was directed at the game’s obstacles, not at the capitalist class, which sets the rules. The inbuilt antagonism between the player and the game replaces, in the mind of the worker, the deeper antagonism between boss and worker. Learning how to operate cleverly within the game’s parameters becomes the only imaginable option. And now there is another layer interposed between labour and capital: the algorithm.
