95-640: The Pixelbook Go (codenamed Atlas during development) is a portable touchscreen laptop computer developed by Google which runs ChromeOS . It was announced on October 15, 2019 as the successor to the Pixelbook , and shipments began on October 27 for the United States and Canada. The Pixelbook Go was later made available for the United Kingdom in January 2020. Unlike preceding Google-branded Chromebook devices,

190-456: A PIN stored on the card was developed by a group of engineers working at Smiths Group on the Chubb MD2 in 1965 and which has been credited to James Goodfellow (patent GB1197183 filed on 2 May 1966 with Anthony Davies). The essence of this system was that it enabled the verification of the customer with the debited account without human intervention. This patent is also the earliest instance of

285-418: A monochrome CRT touchscreen that functioned both as display and sole method of input. The ECC replaced the traditional mechanical stereo , fan, heater and air conditioner controls and displays, and was capable of providing very detailed and specific information about the vehicle's cumulative and current operating status in real time . The ECC was standard equipment on the 1985–1989 Buick Riviera and later

380-559: A telephone line or directly on a leased line. Leased lines are preferable to plain old telephone service (POTS) lines because they require less time to establish a connection. Less-trafficked machines will usually rely on a dial-up modem on a POTS line rather than using a leased line, since a leased line may be comparatively more expensive to operate compared to a POTS line. That dilemma may be solved as high-speed Internet VPN connections become more ubiquitous. Common lower-level layer communication protocols used by ATMs to communicate back to

475-493: A 13.3-inch (340 mm) touchscreen design with an aspect ratio of 16:9; however, with a conventional clamshell hinge, the device cannot be used like a tablet, unlike its predecessor, the Pixelbook . The device also features Google Assistant with a dedicated button. It runs ChromeOS and can launch Android applications natively. The laptop uses a magnesium chassis with an exterior finished in one of two colors, which Google calls "Just Black" and "Not Pink". The bottom chassis has

570-480: A 20 MB hard drive. In order to keep up-to-date information during the event, the database of visitor information was updated and remotely transferred to the computer terminals each night. Using the touch screens, visitors were able to find information about the exposition’s rides, attractions, performances, facilities, and the surrounding areas. Visitors could also select between information displayed in English and Japanese;

665-511: A DACS in 1968 under the 'Scotcash' brand. Customers were given personal code numbers to activate the machines, similar to the modern PIN. They were also supplied with £10 vouchers. These were fed into the machine, and the corresponding amount debited from the customer's account. A Chubb-made ATM appeared in Sydney in 1969. This was the first ATM installed in Australia. The machine only dispensed $ 25 at

760-469: A Docuteller was designed by Donald Wetzel and his company Docutel. Chemical executives were initially hesitant about the electronic banking transition given the high cost of the early machines. Additionally, executives were concerned that customers would resist having machines handling their money. In 1995, the Smithsonian National Museum of American History recognised Docutel and Wetzel as

855-446: A bad reputation of being imprecise until 1988. Most user-interface books would state that touchscreen selections were limited to targets larger than the average finger. At the time, selections were done in such a way that a target was selected as soon as the finger came over it, and the corresponding action was performed immediately. Errors were common, due to parallax or calibration problems, leading to user frustration. "Lift-off strategy"

950-674: A bank branch's capabilities, and are thus more expensive. Off-premises machines are deployed by financial institutions where there is a simple need for cash, so they are generally cheaper single-function devices. Independent ATM deployers unaffiliated with banks install and maintain white-label ATMs . In the US, Canada and some Gulf countries , banks may have drive-thru lanes providing access to ATMs using an automobile. In recent times, countries like India and some countries in Africa are installing solar-powered ATMs in rural areas. The world's highest ATM

1045-606: A complete "currency dispenser system" in the patent record. This patent was filed on 5 March 1968 in the US (US 3543904) and granted on 1 December 1970. It had a profound influence on the industry as a whole. Not only did future entrants into the cash dispenser market such as NCR Corporation and IBM licence Goodfellow's PIN system, but a number of later patents reference this patent as "Prior Art Device". Devices designed by British (i.e. Chubb, De La Rue) and Swedish (i.e. Asea Meteor) manufacturers quickly spread out. For example, given its link with Barclays , Bank of Scotland deployed

1425-416: A matrix of collimated lights shining orthogonally across the touch surface. When a beam is interrupted by a stylus, the photodetectors which no longer are receiving a signal can be used to determine where the interruption is. Later iterations of matrix based touchscreens built upon this by adding more emitters and detectors to improve resolution, pulsing emitters to improve optical signal to noise ratio , and

1520-621: A month. The online version of the Swedish machine is listed to have been operational on 6 May 1968, while claiming to be the first online ATM in the world, ahead of similar claims by IBM and Lloyds Bank in 1971, and Oki in 1970. The collaboration of a small start-up called Speytec and Midland Bank developed a fourth machine which was marketed after 1969 in Europe and the US by the Burroughs Corporation . The patent for this device (GB1329964)

1615-436: A more diverse range of devices to attach to their networks, some interbank networks have passed rules expanding the definition of an ATM to be a terminal that either has the vault within its footprint or utilises the vault or cash drawer within the merchant establishment, which allows for the use of a scrip cash dispenser . ATMs typically connect directly to their host or ATM Controller on either ADSL or dial-up modem over

1710-621: A new ATM at Royal Bank of Scotland allowed customers to withdraw cash up to £130 without a card by inputting a six-digit code requested through their smartphones. ATMs can be placed at any location but are most often placed near or inside banks , shopping centers , airports , railway stations , metro stations , grocery stores , gas stations , restaurants , and other locations. ATMs are also found on cruise ships and on some US Navy ships, where sailors can draw out their pay. ATMs may be on- and off-premises. On-premises ATMs are typically more advanced, multi-function machines that complement

1805-461: A nonorthogonal matrix to remove shadow readings when using multi-touch. 1963 INDIRECT LIGHT PEN - Later inventions built upon this system to free telewriting styli from their mechanical bindings.

Both these devices could only sense the finger by direct touch or through a thin insulating film. This was 11 microns thick according to Stumpe's 1977 report. 1984 TOUCHPAD - Fujitsu released a touch pad for the Micro 16 to accommodate the complexity of kanji characters, which were stored as tiled graphics. 1986 GRAPHIC TABLET - A graphic touch tablet

5605-793: The hardware architecture of a personal computer, such as USB connections for peripherals, Ethernet and IP communications, and use personal computer operating systems. Business owners often lease ATMs from service providers. However, based on the economies of scale, the price of equipment has dropped to the point where many business owners are simply paying for ATMs using a credit card. New ADA voice and text-to-speech guidelines imposed in 2010, but required by March 2012 have forced many ATM owners to either upgrade non-compliant machines or dispose them if they are not upgradable, and purchase new compliant equipment. This has created an avenue for hackers and thieves to obtain ATM hardware at junkyards from improperly disposed decommissioned machines. The vault of an ATM

5700-475: The instructions to use the Bancomat was published in the same newspaper. In West Germany , the first ATM was installed in the 50,000-people university city of Tübingen on May 27, 1968, by Kreissparkasse Tübingen.

To show confidence in Docutel, Chemical installed the first four production machines in a marketing test that proved they worked reliably, customers would use them and even pay a fee for usage. Based on this, banks around the country began to experiment with ATM installations. By 1974, Docutel had acquired 70 percent of the U.S. market; but as a result of the early 1970s worldwide recession and its reliance on

5985-609: The large number of ATMs, there is additional demand for machines in the Asia/Pacific area as well as in Latin America. Macau may have the highest density of ATMs at 254 ATMs per 100,000 adults. With the uptake of cashless payment solutions in the late 2010s, ATM numbers and usage started to decline. This happened first in developed countries at a time when ATM number were still increasing in Asia and Africa. As of 2021 , there had been

6080-475: The length of the horizontal sensing elements increases as the width of the touchscreen increases. Eventually, a limit is hit where the resistance gets so great that the touchscreen can no longer function properly. The patent describes how the use of diagonal elements ensures that the length of any element never exceeds 1.414 times the height ⌈ H 2 ⌋ {\textstyle \left\lceil H{\sqrt {2}}\right\rfloor } of

Internally, the new Pixelbook Go used many of the same components as the preceding Pixel Slate. The two devices were developed closely together in 2018; 'Atlas' (the eventual Pixelbook Go laptop) was to be accompanied by 'Meowth' (a convertible tablet), but due to supply chain issues, development of 'Meowth'

6555-451: The need for direct interaction with bank staff. ATMs are known by a variety of names, including automatic teller machines (ATM) in the United States (sometimes redundantly as "ATM machine"). In Canada, the term automated banking machine (ABM) is also used, although ATM is also very commonly used in Canada, with many Canadian organizations using ATM rather than ABM. In British English,

6650-404: The number of ATMs in use at 3 million units, or approximately 1 ATM per 3,000 people in the world. To simplify the analysis of ATM usage around the world, financial institutions generally divide the world into seven regions, based on the penetration rates, usage statistics, and features deployed. Four regions (USA, Canada, Europe, and Japan) have high numbers of ATMs per million people. Despite

6745-589: The original signal. Effectively, this was used for temporarily drawing arrows or circles onto a live television broadcast, as described in US 2487641A , Denk, William E, "Electronic pointer for television images", issued 1949-11-08   . 1962 OPTICAL - The first version of a touchscreen which operated independently of the light produced from the screen was patented by AT&T Corporation US 3016421A , Harmon, Leon D, "Electrographic transmitter", issued 1962-01-09   . This touchscreen utilized

6840-958: The release of the Nintendo DS in 2004. 2007 MOBILE PHONE WITH CAPACITANCE - The first mobile phone with a capacitive touchscreen was LG Prada , released in May 2007 (which was before the first iPhone released). By 2009, touchscreen-enabled mobile phones were becoming trendy and quickly gaining popularity in both basic and advanced devices. In Quarter-4 2009 for the first time, a majority of smartphones (i.e. not all mobile phones) shipped with touchscreens over non-touch. 2013 RESISTIVE VERSUS PROJECTED CAPACITANCE SALES - In 2007, 93% of touchscreens shipped were resistive and only 4% were projected capacitance. In 2013, 3% of touchscreens shipped were resistive and 96% were projected capacitance (see page 5). 2015 FORCE SENSING TOUCHSCREENS - Until recently, most consumer touchscreens could only sense one point of contact at

6935-411: The screen and a matched phototransistor on the other edge, all mounted in front of a monochrome plasma display panel. This arrangement could sense any fingertip-sized opaque object in close proximity to the screen. 1973 MULTI-TOUCH CAPACITANCE - In 1973, Beck and Stumpe published another article describing their capacitive touchscreen. This indicated that it was capable of multi-touch but this feature

7030-538: The screen to activate a switch (or a U-shaped gesture for a toggle switch). The HCIL team developed and studied small touchscreen keyboards (including a study that showed users could type at 25 wpm on a touchscreen keyboard), aiding their introduction on mobile devices. They also designed and implemented multi-touch gestures such as selecting a range of a line, connecting objects, and a "tap-click" gesture to select while maintaining location with another finger. 1990 TOUCHSCREEN SLIDER AND TOGGLE SWITCHES - HCIL demonstrated

7125-422: The screen with a special stylus or one or more fingers. Some touchscreens use ordinary or specially coated gloves to work, while others may only work using a special stylus or pen. The user can use the touchscreen to react to what is displayed and, if the software allows, to control how it is displayed; for example, zooming to increase the text size. A touchscreen enables the user to interact directly with what

7220-491: The teller. During a transaction , the customer's account number was read by the card reader . This process replaced manual entry and avoided possible key stroke errors. It allowed users to replace traditional customer verification methods such as signature verification and test questions with a secure PIN system. The success of the "Atalla Box" led to the wide adoption of hardware security modules in ATMs. Its PIN verification process

7315-454: The terms cashpoint , cash machine and hole in the wall are also used. ATMs that are not operated by a financial institution are known as " white-label " ATMs. Using an ATM, customers can access their bank deposit or credit accounts in order to make a variety of financial transactions, most notably cash withdrawals and balance checking, as well as transferring credit to and from mobile phones. ATMs can also be used to withdraw cash in

7410-517: The time and an input at other times. I/Os are inputs most of the time, but, once every scan, one of the I/Os has to take its turn at being an output, the remaining input I/Os sensing any signals it generates. The I/O lines, therefore, may have to change from input to output, and vice versa, many times a second. This new design won an Electronics Weekly Elektra Award in 2017. 2021 FIRST "INFINITELY WIDE" TOUCHSCREEN PATENT - With standard x/y array touchscreens,

7505-538: The touchscreen, no matter how wide it is. This could be reduced to 1.15 times the height, if opposing diagonal elements intersect at 60 degrees instead of 90 degrees. The elongated touchscreen could be controlled by a single processor, or the distant ends could be controlled totally independently by different processors, linked by a synchronizing processor in the overlapping middle section. The number of unique intersections could be increased by allowing individual sensing elements to run in two opposing directions - as shown in

7600-449: The trend toward acceptance of touchscreens as a user interface component and have begun to integrate touchscreens into the fundamental design of their products. One predecessor of the modern touchscreen includes stylus based systems. 1946 DIRECT LIGHT PEN - A patent was filed by Philco Company for a stylus designed for sports telecasting which, when placed against an intermediate cathode-ray tube (CRT) display would amplify and add to

7695-636: Was Sega 's intended successor to the Game Gear , though the device was ultimately shelved and never released due to the expensive cost of touchscreen technology in the early 1990s. 1994 FIRST WIRE BASED PROJECTED CAPACITANCE - Stumpe and Beck's touchscreens (1972/1977 - already cited), used opaque conductive copper tracks that obscured about 50% of the screen (80 micron track / 80 micron space). The advent of projected capacitance in 1984, however, with its improved sensing capability, indicated that most of these tracks could be eliminated. This proved to be so, and led to

7790-451: Was a true ATM, similar in function to today's machines and named Cashpoint by Lloyds Bank. Cashpoint is still a registered trademark of Lloyds Banking Group in the UK but is often used as a generic trademark to refer to ATMs of all UK banks. All were online and issued a variable amount which was immediately deducted from the account. A small number of 2984s were supplied to a U.S. bank. A couple of well known historical models of ATMs include

7885-674: Was demonstrated on the 16-bit Atari 520ST color computer. It featured a color touchscreen widget-driven interface. The ViewTouch POS software was first shown by its developer, Gene Mosher, at the Atari Computer demonstration area of the Fall COMDEX expo in 1986. 1987 CAPACITANCE TOUCH KEYS - Casio launched the Casio PB-1000 pocket computer with a touchscreen consisting of a 4×4 matrix, resulting in 16 touch areas in its small LCD graphic screen. 1988 SELECT ON "LIFT-OFF" - Touchscreens had

7980-550: Was developed by Eric Johnson, of the Royal Radar Establishment located in Malvern , England, who described his work on capacitive touchscreens in a short article published in 1965 and then more fully—with photographs and diagrams—in an article published in 1967. MID-60s ULTRASONIC CURTAIN - Another precursor of touchscreens, an ultrasonic-curtain-based pointing device in front of a terminal display, had been developed by

8075-469: Was discontinued in favor of 'Nocturne' (which eventually became the Pixel Slate). Preorders were opened the same day as the announcement, October 15, 2019, and shipments for the Pixelbook Go began on October 27. The top-end version with a Core i7 processor was not available to order until December 2019. The Pixelbook Go was made available for the United Kingdom on January 15, 2020. The Pixelbook Go features

8170-623: Was filed in September 1969 (and granted in 1973) by John David Edwards, Leonard Perkins, John Henry Donald, Peter Lee Chappell, Sean Benjamin Newcombe, and Malcom David Roe. Both the DACS and MD2 accepted only a single-use token or voucher which was retained by the machine, while the Speytec worked with a card with a magnetic stripe at the back. They used principles including Carbon-14 and low-coercivity magnetism in order to make fraud more difficult. The idea of

8265-516: Was installed in New York City in 1961 by the City Bank of New York , but removed after six months due to the lack of customer acceptance. In 1962 Adrian Ashfield invented the idea of a card system to securely identify a user and control and monitor the dispensing of goods or services. This was granted UK Patent 959,713 in June 1964 and assigned to Kins Developments Limited. A Japanese device called

8360-488: Was introduced by researchers at the University of Maryland Human–Computer Interaction Lab (HCIL). As users touch the screen, feedback is provided as to what will be selected: users can adjust the position of the finger, and the action takes place only when the finger is lifted off the screen. This allowed the selection of small targets, down to a single pixel on a 640×480 Video Graphics Array (VGA) screen (a standard of that time). 1988 WORLD EXPO - From April to October 1988,

8455-639: Was later resolved by using finer (10 micron diameter), dark coated wires. Throughout the following decade JPM continued to use touchscreens for many other games such as "Cluedo" and "Who wants to be a Millionaire". 1998 PROJECTED CAPACITANCE LICENSES - This technology was licensed four years later to Romag Glass Products - later to become Zytronic Displays, and Visual Planet in 2003 (see page 4). 2004 MOBILE MULTI-TOUCH PROJECTED CAPACITANCE PATENT - Apple patents its multi-touch capacitive touchscreen for mobile devices. 2004 VIDEO GAMES WITH TOUCHSCREENS - Touchscreens were not be popularly used for video games until

8550-565: Was producing optical scanning equipment and had instructed Docutel to explore automated baggage handling and automated gasoline pumps. On 2 September 1969, Chemical Bank installed a prototype ATM in the U.S. at its branch in Rockville Centre, New York . The first ATMs were designed to dispense a fixed amount of cash when a user inserted a specially coded card. A Chemical Bank advertisement boasted "On Sept. 2 our bank will open at 9:00 and never close again." Chemical's ATM, initially known as

8645-590: Was purposely inhibited, presumably as this was not considered useful at the time ("A...variable...called BUT changes value from zero to five when a button is touched. The touching of other buttons would give other non-zero values of BUT but this is protected against by software" (Page 6, section 2.6). "Actual contact between a finger and the capacitor is prevented by a thin sheet of plastic" (Page 3, section 2.3). At that time Projected capacitance had not yet been invented. 1977 RESISTIVE - An American company, Elographics – in partnership with Siemens – began work on developing

8740-475: Was released for the Sega AI Computer . EARLY 80s EVALUATION FOR AIRCRAFT - Touch-sensitive control-display units (CDUs) were evaluated for commercial aircraft flight decks in the early 1980s. Initial research showed that a touch interface would reduce pilot workload as the crew could then select waypoints, functions and actions, rather than be "head down" typing latitudes, longitudes, and waypoint codes on

8835-461: Was similar to the later IBM 3624 . Atalla's HSM products protect 250   million card transactions every day as of 2013, and secure the majority of the world's ATM transactions as of 2014. The IBM 2984 was a modern ATM and came into use at Lloyds Bank, High Street, Brentwood, Essex, the UK in December 1972. The IBM 2984 was designed at the request of Lloyds Bank . The 2984 Cash Issuing Terminal

8930-529: Was that the Boie technology would become available to us in the near future. Around 1990 I took a group from Xerox to see this technology it [sic] since I felt that it would be appropriate for the user interface of our large document processors. This did not work out". UP TO 1984 CAPACITANCE - Although, as cited earlier, Johnson is credited with developing the first finger operated capacitive and resistive touchscreens in 1965, these worked by directly touching wires across

9025-412: Was the first machine to use touch screen technology instead of buttons (see Quiz machine / History). It used a 14 inch version of this newly invented wire based projected capacitance touchscreen and had 64 sensing areas - the wiring pattern being similar to that shown in the lower diagram. The zig-zag pattern was introduced to minimize visual reflections and prevent Moire interference between the wires and
