Android is an operating system based on the Linux kernel and designed primarily for touchscreen mobile devices such as smart- phones and tablet computers. user interfaces suitable for typical user interaction on Android smartphone and tablets UI designs are copied indiscriminately, an Android device will present a terrible UI ApressOpen eBooks are available in PDF, ePub, and Mobi formats . “Android User Interface Design is a truly excellent book, written by one of the most needed to understand how to design Android apps that stand out.”.
Answer: Yes. Please contact me personally. Question: Am I too much of a beginner for this course? Learn UI Design is created to bring you from zero experience to a professional level of UI design skills. Although many students have entered with formal training in visual design, the majority have none.

Book Details Author: The software interface was similarly unforgiving, with very strict syntaxes meant to be parsed by the smallest possible compilers and interpreters. Holes are punched in the card according to a prearranged code transferring the facts from the census questionnaire into statistics Once the cards were punched, one would drop them in a job queue and wait.
Eventually, operators would feed the deck to the computer, perhaps mounting magnetic tapes to supply another dataset or helper software. The job would generate a printout, containing final results or all too often an abort notice with an attached error log.
Successful runs might also write a result on magnetic tape or generate some data cards to be used in a later computation. The turnaround time for a single job often spanned entire days. If one were very lucky, it might be hours; there was no real-time response.
But there were worse fates than the card queue; some computers required an even more tedious and error-prone process of toggling in programs in binary code using console switches. The very earliest machines had to be partly rewired to incorporate program logic into themselves, using devices known as plugboards.
These used a monitor program which was always resident on the computer. Programs could call the monitor for services. Another function of the monitor was to do better error checking on submitted jobs, catching errors earlier and more intelligently and generating more useful feedback to the users.
Thus, monitors represented the first step towards both operating systems and explicitly designed user interfaces. Their interaction model was a series of request-response transactions, with requests expressed as textual commands in a specialized vocabulary. Latency was far lower than for batch systems, dropping from days or hours to seconds.
Accordingly, command-line systems allowed the user to change his or her mind about later stages of the transaction in response to real-time or near-real-time feedback on earlier results. Software could be exploratory and interactive in ways not possible before.
But these interfaces still placed a relatively heavy mnemonic load on the user, requiring a serious investment of effort and learning time to master. Teleprinters had originally been invented as devices for automatic telegraph transmission and reception; they had a history going back to and had already become well-established in newsrooms and elsewhere by In reusing them, economy was certainly a consideration, but psychology and the Rule of Least Surprise mattered as well; teleprinters provided a point of interface with the system that was familiar to many engineers and users.
These cut latency further, because characters could be thrown on the phosphor dots of a screen more quickly than a printer head or carriage can move. They helped quell conservative resistance to interactive programming by cutting ink and paper consumables out of the cost picture, and were to the first TV generation of the late s and 60s even more iconic and comfortable than teleprinters had been to the computer pioneers of the s.
Just as importantly, the existence of an accessible screen — a two-dimensional display of text that could be rapidly and reversibly modified — made it economical for software designers to deploy interfaces that could be described as visual rather than textual.
The pioneering applications of this kind were computer games and text editors; close descendants of some of the earliest specimens, such as rogue 6 , and vi 1 , are still a live part of Unix tradition. This defined that a pulldown menu system should be at the top of the screen, status bar at the bottom, shortcut keys should stay the same for all common functionality F2 to Open for example would work in all applications that followed the SAA standard. This greatly helped the speed at which users could learn an application so it caught on quick and became an industry standard.
