Casio Digital Diary
An electronic organizer (or electric organizer) is a small calculator-sized computer, often with an built-in diary application and other functions such as an address book and calendar, replacing paper-based personal organizers. It normally has a small alphanumeric keypad and an LCD screen of one, two, or three lines. The electronic diary or organizer was invented by Indian businessman Satyan Pitroda in 1975. He is regarded as one of the earliest pioneers of hand-held computing because of his invention of the Electronic Diary in 1975. They were very popular especially with businessmen during the 1990s, but because of the advent of palmtop PCs in the 1990s, personal digital assistants in the 2000s, and smartphones in the 2010s, all of which have a larger set of features, electronic organizers are mostly seen today for research purposes. One of the leading research topics being the study of how electronics can help people with mental disabilities use this type of equipment to aid ...

Personal Digital Assistant
A personal digital assistant (PDA), also known as a handheld PC, is a variety mobile device which functions as a personal information manager. PDAs have been mostly displaced by the widespread adoption of highly capable smartphones, in particular those based on iOS and Android. A PDA has an electronic visual display. Most models also have audio capabilities, allowing usage as a portable media player, and also enabling many of them to be used as telephones. Nearly all modern PDAs can access the Internet, intranets or extranets via Wi-Fi or Wireless WANs, letting them include a web browser. Sometimes, instead of buttons, PDAs employ touchscreen technology. The first PDA, the Organiser, was released in 1984 by Psion, followed by Psion's Series 3, in 1991. The latter began to resemble the more familiar PDA style, including a full keyboard. The term ''PDA'' was first used on January 7, 1992 by Apple Inc. CEO John Sculley at the Consumer Electronics Show in Las Vegas, Nevad ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Smartphone
A smartphone is a portable computer device that combines mobile telephone and computing functions into one unit. They are distinguished from feature phones by their stronger hardware capabilities and extensive mobile operating systems, which facilitate wider software, internet (including web browsing over mobile broadband), and multimedia functionality (including music, video, cameras, and gaming), alongside core phone functions such as voice calls and text messaging. Smartphones typically contain a number of metal–oxide–semiconductor (MOS) integrated circuit (IC) chips, include various sensors that can be leveraged by pre-included and third-party software (such as a magnetometer, proximity sensors, barometer, gyroscope, accelerometer and more), and support wireless communications protocols (such as Bluetooth, Wi-Fi, or satellite navigation). Early smartphones were marketed primarily towards the enterprise market, attempting to bridge the functionality of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Electronic Dictionary
An electronic dictionary is a dictionary whose data exists in digital form and can be accessed through a number of different media. Electronic dictionaries can be found in several forms, including software installed on tablet or desktop computers, mobile apps, web applications, and as a built-in function of E-readers. They may be free or require payment. Information Most of the early electronic dictionaries were, in effect, print dictionaries made available in digital form: the content was identical, but the electronic editions provided users with more powerful search functions. But soon the opportunities offered by digital media began to be exploited. Two obvious advantages are that limitations of space (and the need to optimize its use) become less pressing, so additional content can be provided; and the possibility arises of including multimedia content, such as audio pronunciations and video clips. Electronic dictionary databases, especially those included with software d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sharp Electronics
is a Japanese multinational corporation that designs and manufactures electronic products, headquartered in Sakai-ku, Sakai, Osaka Prefecture. Since 2016 it has been majority owned by the Taiwan-based Foxconn Group. Sharp employs more than 50,000 people worldwide. The company was founded in September 1912 in Tokyo and takes its name from one of its founder's first Ever-Sharp mechanical pencil, which was invented by Tokuji Hayakawa in 1915. History Early years 1912–1945 In 1912, Tokuji Hayakawa founded a metal workshop in Tokyo. The first of his many inventions was a snap buckle named 'Tokubijo'. Another of his inventions was the Ever-Ready Sharp mechanical pencil in 1915. The product became one of the first internationally available mechanical pencils (while concurrent US design replaced it soon and became a modern type), and due to this big success the Sharp Corporation derived its name from it. After the pencil business was destroyed by the 1923 Great Kantō earthquake, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rolodex
A Rolodex is a rotating card file device used to store business contact information. Its name, a portmanteau of the words ''rolling'' and ''index'', has become somewhat genericized (usually as ''rolodex'') for any personal organizer performing this function, or as a metonym for the total of an individual's accumulated business contacts. In this usage, it has generally come to describe an effect or characteristic of the small-world network of a business's investors, board of directors, or the value of a CEO's contacts, or in organizational structure. The Rolodex is iconic enough as a piece of ubiquitous business furniture that it has been shown in the Smithsonian. History The Rolodex was invented in 1956 by Danish engineer Hildaur Neilsen, the chief engineer of Arnold Neustadter's company Zephyr American, a stationery manufacturer in New York. Neustadter was often credited with having invented it. First marketed in 1958, it was an improvement to an earlier design called the ''Whe ...

Casio
is a Japanese multinational electronics manufacturing corporation headquartered in Shibuya, Tokyo, Japan. Its products include calculators, mobile phones, digital cameras, electronic musical instruments, and analogue and digital watches. It was founded in 1946, and in 1957 introduced the world's first entirely compact electronic calculator. It was an early digital camera innovator, and during the 1980s and 1990s, the company developed numerous affordable home electronic keyboards for musicians along with introducing the world's first mass-produced digital watches. History Casio was established as Kashio Seisakujo in April 1946 by Tadao Kashio ( 樫尾忠雄 1917–1993), an engineer specializing in fabrication technology. Kashio's first major product was the yubiwa pipe, a finger ring that would hold a cigarette, allowing the wearer to smoke the cigarette down to its nub while also leaving the wearer's hands free. Japan was impoverished immediately following World War II, so ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Palmtop PC
A handheld personal computer (PC) is a miniature computer typically built around a clamshell form factor and is significantly smaller than any standard laptop computer, but based on the same principles. It is sometimes referred to as a ''palmtop computer'', not to be confused with Palmtop PC which was a name used mainly by Hewlett-Packard. Most handheld PCs use an operating system specifically designed for mobile use. Ultra-compact laptops capable of running common x86-compatible desktop operating systems are typically classified as subnotebooks. The first hand-held device compatible with desktop IBM personal computers of the time was the Atari Portfolio of 1989. Other early models were the Poqet PC of 1989 and the Hewlett Packard HP 95LX of 1991 which run the MS-DOS operating system. Other DOS-compatible hand-held computers also existed. After 2000 the handheld PC segment practically halted, replaced by other forms, although later communicators such as Nokia E90 can be conside ...
