【實用生產應用app】Okk (One key keyboard)|最夯免費app-綠色工廠好玩App

okk (One Key Keyboard) is an App designed to aid people with Severe Motor Impairments / Autism - to enter text into apps on a Smartphone.

The Virtual Keyboards present on most mobile phones occupy a small portion of the screen and are cluttered with too many keys. this makes it difficult for people with certain medical conditions (such as Cerebral Palsy) to use a smartphone. essentially, these people don't have a fine degree of control over their movements. So, selecting particular keys from the virtual keyboard (in order to type words and sentences) becomes difficult. Typos are another annoying factor. When typos occur - it further agitates these users - resulting in even more typos. eventually they reach a point where they resist using such devices / technology.

people with autism have a different problem. people with certain types of Autism tend to get confused when multiple options are presented in front of them. Here, there is no physical barrier. But the inability to determine which key to select - prevents them from being able to use a smartphone effectively. Instead, if only one option is presented to them at regular intervals - they will be able to make the right selection every time.

okk is an app that aims to fill both these gaps. The core concept of the app is to have a virtual keyboard with only one key. Some of the features (already implemented) include……

* facility to type almost any character on the keyboard – just by using one key / button

* Option to change which group of characters appear on the button (such as Alphabets, Numbers – and combinations of them) – this can be done on the fly

* Option to change the delay between characters appearing on the button [this can also be done on the fly]

* Basic level of Word Prediction - to increase speed of typing.......

-> This is available only for English language

-> At present - there is no Intelligent Prediction [no option to add / remove / change order of words in the dictionary]

* Option to send the typed text to other Apps (such as Dialer / browser / save as note etc.) – this may not work well in all cases

* Option to change Language – this feature was developed only to show that this app can handle other languages (rendering of text in other languages needs a significant amount of work to be done). Enhancements with respect to this feature can be taken up as part of the next version

Known issues..........

* The UI may not be beautiful (it could even be Ugly – depends on the device being used). But I think it definitely serves the purpose

* Only basic level of word prediction is available in this version

* Output redirection to other Apps – may not work in all cases

* Text rendering in other languages is not properly implemented

* Languages cannot be added / deleted by users (at present – there is no interface provided to do this)

* Latency in performance – might cause slight issues

Feature Enhancements planned for the next major release.........

* at present, okk is implemented as a traditional Android App. However, it needs to be implemented as an Input Method Service. During the development - some complex issues were encountered, which made it very difficult to arrive at a workable solution within the given time. So i decided to abandon the Input method approach for now.

in the next release however - okk will be implemented as an Input Method Service. This would give the user a whole host of benefits. Some of these benefits are.......

-> ability to call the okk service from any other app
