Question: When did person who supervised the design and implementation of the iPod user interface die?

full_context: Document 1: IPod: Though the iPod was released in 2001, its price and Mac-only compatibility caused sales to be relatively slow until 2004. The iPod line came from Apple's "digital hub" category, when the company began creating software for the growing market of personal digital devices. Digital cameras, camcorders and organizers had well-established mainstream markets, but the company found existing digital music players "big and clunky or small and useless" with user interfaces that were "unbelievably awful," so Apple decided to develop its own. As ordered by CEO Steve Jobs, Apple's hardware engineering chief Jon Rubinstein assembled a team of engineers to design the iPod line, including hardware engineers Tony Fadell and Michael Dhuey, and design engineer Sir Jonathan Ive. Rubinstein had already discovered the Toshiba disk drive when meeting with an Apple supplier in Japan, and purchased the rights to it for Apple, and had also already worked out how the screen, battery, and other key elements would work. The aesthetic was inspired by the 1958 Braun T3 transistor radio designed by Dieter Rams, while the wheel based user interface was prompted by Bang & Olufsen's BeoCom 6000 telephone. The product ("the Walkman of the twenty-first century" ) was developed in less than one year and unveiled on October 23, 2001. Jobs announced it as a Mac-compatible product with a 5 GB hard drive that put "1,000 songs in your pocket."
Document 2: Emotion: Some of the most influential theorists on emotion from the 20th century have died in the last decade. They include Magda B. Arnold (1903–2002), an American psychologist who developed the appraisal theory of emotions; Richard Lazarus (1922–2002), an American psychologist who specialized in emotion and stress, especially in relation to cognition; Herbert A. Simon (1916–2001), who included emotions into decision making and artificial intelligence; Robert Plutchik (1928–2006), an American psychologist who developed a psychoevolutionary theory of emotion; Robert Zajonc (1923–2008) a Polish–American social psychologist who specialized in social and cognitive processes such as social facilitation; Robert C. Solomon (1942–2007), an American philosopher who contributed to the theories on the philosophy of emotions with books such as What Is An Emotion?: Classic and Contemporary Readings (Oxford, 2003); Peter Goldie (1946–2011), a British philosopher who specialized in ethics, aesthetics, emotion, mood and character; Nico Frijda (1927–2015), a Dutch psychologist who advanced the theory that human emotions serve to promote a tendency to undertake actions that are appropriate in the circumstances, detailed in his book The Emotions (1986).
Document 3: IPod: Apple did not develop the iPod software entirely in-house, instead using PortalPlayer's reference platform based on two ARM cores. The platform had rudimentary software running on a commercial microkernel embedded operating system. PortalPlayer had previously been working on an IBM-branded MP3 player with Bluetooth headphones. Apple contracted another company, Pixo, to help design and implement the user interface under the direct supervision of Steve Jobs. As development progressed, Apple continued to refine the software's look and feel. Starting with the iPod Mini, the Chicago font was replaced with Espy Sans. Later iPods switched fonts again to Podium Sans—a font similar to Apple's corporate font, Myriad. iPods with color displays then adopted some Mac OS X themes like Aqua progress bars, and brushed metal meant to evoke a combination lock. In 2007, Apple modified the iPod interface again with the introduction of the sixth-generation iPod Classic and third-generation iPod Nano by changing the font to Helvetica and, in most cases, splitting the screen in half by displaying the menus on the left and album artwork, photos, or videos on the right (whichever was appropriate for the selected item).
Document 4: IPod Mini: The iPod Mini used the touch-sensitive scroll wheel of the third generation iPod. However, instead of the four touch buttons located above the wheel, the buttons were redesigned as mechanical switches beneath the wheel itself—hence the name "click wheel". To use one of the four buttons, the user physically pushes the edge of the wheel inward over one of the four labels. Like its predecessors, the wheel was developed for Apple by Synaptics. The click wheel is now also used in the fourth, fifth and sixth generation iPods and the iPod Nano, from first generation through the fifth; however, in the Nano and 5G iPods onwards, the click wheel used was developed by Apple.
Document 5: IPod: Before the release of iOS 5, the iPod branding was used for the media player included with the iPhone and iPad, a combination of the Music and Videos apps on the iPod Touch. As of iOS 5, separate apps named "Music" and "Videos" are standardized across all iOS-powered products. While the iPhone and iPad have essentially the same media player capabilities as the iPod line, they are generally treated as separate products. During the middle of 2010, iPhone sales overtook those of the iPod.
Document 6: Inside Out (2015 film): In late 2009, Docter noticed his pre-teen daughter, Elie, exhibiting similar shyness. "She started getting more quiet and reserved, and that, frankly, triggered a lot of my own insecurities and fears," he said. He imagined what happens in the human mind when emotions set in. The idea to depict it through animation excited Docter, who felt it the ideal form to portray "strong, opinionated, caricatured personalities". He began researching information about the mind, alongside Jonas Rivera, a producer, and Ronnie del Carmen, a secondary director. They consulted Paul Ekman, a well-known psychologist who studies emotions, and Dacher Keltner, a professor of psychology at the University of California, Berkeley. Ekman had early in his career identified six core emotions—anger, fear, sadness, disgust, joy, and surprise. Docter found surprise and fear to be too similar, which left him with five emotions to build characters around. Other emotions considered for inclusion during the development process were schadenfreude, ennui, pride, and hope. Keltner focused on sadness being an emotion that strengthens relationships. Both emphasized how emotions organize social lives and the structuring of interpersonal interactions.The smash success of Docter's 2009 film Up encouraged those at Pixar to allow Docter to create another film with a more sophisticated story. Inside Out is the first Pixar film without input from co-founder and former Apple CEO Steve Jobs, who died in 2011. In addition, the film did not have as much input from chief creative officer John Lasseter, who was focused on restructuring Walt Disney Animation Studios in Burbank at the time of its production. Executives at Disney and Pixar were positive at the proposal of making Inside Out, but acknowledged it would be difficult to market.
Document 7: IPod: iPods with color displays use anti-aliased graphics and text, with sliding animations. All iPods (except the 3rd-generation iPod Shuffle, the 6th & 7th generation iPod Nano, and iPod Touch) have five buttons and the later generations have the buttons integrated into the click wheel – an innovation that gives an uncluttered, minimalist interface. The buttons perform basic functions such as menu, play, pause, next track, and previous track. Other operations, such as scrolling through menu items and controlling the volume, are performed by using the click wheel in a rotational manner. The 3rd-generation iPod Shuffle does not have any controls on the actual player; instead it has a small control on the earphone cable, with volume-up and -down buttons and a single button for play and pause, next track, etc. The iPod Touch has no click-wheel; instead it uses a 3.5" touch screen along with a home button, sleep/wake button and (on the second and third generations of the iPod Touch) volume-up and -down buttons. The user interface for the iPod Touch is identical to that of the iPhone. Differences include a lack of a phone application. Both devices use iOS.
Document 8: Emotion: In the 1990s, sociologists focused on different aspects of specific emotions and how these emotions were socially relevant. For Cooley (1992), pride and shame were the most important emotions that drive people to take various social actions. During every encounter, he proposed that we monitor ourselves through the "looking glass" that the gestures and reactions of others provide. Depending on these reactions, we either experience pride or shame and this results in particular paths of action. Retzinger (1991) conducted studies of married couples who experienced cycles of rage and shame. Drawing predominantly on Goffman and Cooley's work, Scheff (1990) developed a micro sociological theory of the social bond. The formation or disruption of social bonds is dependent on the emotions that people experience during interactions.
Document 9: Up (2009 film): Jordan Nagai as Russell. Throughout most of the film, he makes several comments to Carl that suggest that Russell's father and mother are no longer together. Russell's design was based on Pixar animator Peter Sohn. Docter auditioned 400 boys in a nationwide casting call for the part. Nagai, who is Japanese American, showed up to an audition with his brother, who was actually the one auditioning. Docter realized Nagai behaved and spoke non-stop like Russell and chose him for the part. Nagai was eight years old when cast. Docter encouraged Nagai to act physically as well as vocally when recording the role, lifting him upside down and tickling him for the scene where Russell encounters Kevin. Asian Americans have positively noted Pixar's first casting of an Asian lead character, in contrast to the common practice of casting non-Asians in Asian parts.
Document 10: Typography of Apple Inc.: Starting with the release of the Apple Watch, Apple has begun usage of San Francisco as the typeface of word marks such as ``iPhone '',`` AirPods'', and ``MacBook Pro ''on the devices themselves. This change is also reflected on some headlines on product marketing webpages. Apple modified the majority of its website's text to use the San Francisco font on January 24, 2017, and San Francisco became the universal official font for Apple.
Document 11: IPod: The name iPod was proposed by Vinnie Chieco, a freelance copywriter, who (with others) was called by Apple to figure out how to introduce the new player to the public. After Chieco saw a prototype, he thought of the movie 2001: A Space Odyssey and the phrase "Open the pod bay door, Hal!", which refers to the white EVA Pods of the Discovery One spaceship. Chieco saw an analogy to the relationship between the spaceship and the smaller independent pods in the relationship between a personal computer and the music player. Apple researched the trademark and found that it was already in use. Joseph N. Grasso of New Jersey had originally listed an "iPod" trademark with the U.S. Patent and Trademark Office (USPTO) in July 2000 for Internet kiosks. The first iPod kiosks had been demonstrated to the public in New Jersey in March 1998, and commercial use began in January 2000, but had apparently been discontinued by 2001. The trademark was registered by the USPTO in November 2003, and Grasso assigned it to Apple Computer, Inc. in 2005.
Document 12: Emotion: Robert Plutchik agreed with Ekman's biologically driven perspective but developed the "wheel of emotions", suggesting eight primary emotions grouped on a positive or negative basis: joy versus sadness; anger versus fear; trust versus disgust; and surprise versus anticipation. Some basic emotions can be modified to form complex emotions. The complex emotions could arise from cultural conditioning or association combined with the basic emotions. Alternatively, similar to the way primary colors combine, primary emotions could blend to form the full spectrum of human emotional experience. For example, interpersonal anger and disgust could blend to form contempt. Relationships exist between basic emotions, resulting in positive or negative influences.
Document 13: Emotion: More contemporary views along the evolutionary psychology spectrum posit that both basic emotions and social emotions evolved to motivate (social) behaviors that were adaptive in the ancestral environment. Current research[citation needed] suggests that emotion is an essential part of any human decision-making and planning, and the famous distinction made between reason and emotion is not as clear as it seems. Paul D. MacLean claims that emotion competes with even more instinctive responses, on one hand, and the more abstract reasoning, on the other hand. The increased potential in neuroimaging has also allowed investigation into evolutionarily ancient parts of the brain. Important neurological advances were derived from these perspectives in the 1990s by Joseph E. LeDoux and António Damásio.
Document 14: Emotion: A common way in which emotions are conceptualized in sociology is in terms of the multidimensional characteristics including cultural or emotional labels (e.g., anger, pride, fear, happiness), physiological changes (e.g., increased perspiration, changes in pulse rate), expressive facial and body movements (e.g., smiling, frowning, baring teeth), and appraisals of situational cues. One comprehensive theory of emotional arousal in humans has been developed by Jonathan Turner (2007: 2009). Two of the key eliciting factors for the arousal of emotions within this theory are expectations states and sanctions. When people enter a situation or encounter with certain expectations for how the encounter should unfold, they will experience different emotions depending on the extent to which expectations for Self, other and situation are met or not met. People can also provide positive or negative sanctions directed at Self or other which also trigger different emotional experiences in individuals. Turner analyzed a wide range of emotion theories across different fields of research including sociology, psychology, evolutionary science, and neuroscience. Based on this analysis, he identified four emotions that all researchers consider being founded on human neurology including assertive-anger, aversion-fear, satisfaction-happiness, and disappointment-sadness. These four categories are called primary emotions and there is some agreement amongst researchers that these primary emotions become combined to produce more elaborate and complex emotional experiences. These more elaborate emotions are called first-order elaborations in Turner's theory and they include sentiments such as pride, triumph, and awe. Emotions can also be experienced at different levels of intensity so that feelings of concern are a low-intensity variation of the primary emotion aversion-fear whereas depression is a higher intensity variant.
Document 15: IPod: The dock connector also allowed the iPod to connect to accessories, which often supplement the iPod's music, video, and photo playback. Apple sells a few accessories, such as the now-discontinued iPod Hi-Fi, but most are manufactured by third parties such as Belkin and Griffin. Some peripherals use their own interface, while others use the iPod's own screen. Because the dock connector is a proprietary interface, the implementation of the interface requires paying royalties to Apple.
