Comparison Between Menu Interface and Voice Actuated Interface

By

  1. Menu interface

  • This type of interface lets you interact with a computer or device by working your way through a series of screens or menus.
  • menu driven interfaceThink about your iPod or mobile phone, they both use a menu driven interface. You are presented with a menu, you make a choice and then the next menu appears on the screen. You make another choice and so on.
  • Cashpoint machines (ATMs) are another good example of a menu driven interface.
  • Menu driven interfaces can also be verbal rather than visual. Have you ever made a telephone call and been asked to 'press 1 for abc, press 2 for def, press 3 for ghi'?
  • Most of the software that you use have menu interfaces. You can use many features of the software by working your way through the menu options. Have a look at the menus in your word processor or spreadsheet package and see how many different choices you are given.
  • A well designed menu interface is simple to use, you just follow the instructions and make your choice

Advantage and disadvantage of menu interface.

AdvantagesDisadvantages
Extremely easy to use. Someone who has never seen the interface before can work out what to doA poorly designed menu interface may be slow to use
There are no commands to learn or rememberIt can be irritating if there are too many menu screens to work through - users get annoyed or bored if it takes too long
Step-by-step options are given so that the user doesn't have to remember anythingYou often can't go to the exact place you want right at the start. You have to work your way through the menu screens even if you know where you want to get to.
Even if you don't know what to do, you can usually guess your way around the optionsThe menu can take up a large part of the screen so you have to keep flicking back and forwards between applications
Menu interfaces don't have to be visual, they can be spoken - good for telephones or for visually impaired peopleIf the menu is poorly designed it might be hard to read e.g. writing is too small for people with poor sight, colours might clash and be difficult to read, font style might be hard to read.
They don't need huge amounts of processing power or memory
It is fairly easy for the software programmer to create the same menus in different languages


2.Voice actuated interface


A voice-actuated environmental operator system of the kind which enables a user/patient to use simple voice commands to control a plurality of hospital environment room functions including operation of selected bed movement and room environment functions associated with a provided multi-function hospital bed.

The operator system uses a conventional IBM PC, XT, AT or like computer which has been adapted for interfacing in a pass-through manner with the control unit of a provided hospital bed.

The computer includes a voice card and associated voice recognition and training software for interpreting and translating voice input into digital information readable by a controller card for operating a plurality of bed motor and room function commands. The controller card includes a plurality of relay switch devices, each of which are dedicated to performing a specific bed movement or room function.

An FCC registered data access arrangement is also provided to the controller card for telephone interface capability. In a first embodiment, data communication between the computer and the provided hospital bed's control unit is by pass-through hard wire cable interface connection between bed control unit and the DB9 and DB15 serial port connectors on the back of the computer. The DB9 and DB15 serial port connectors are desoddered off the computer's motherboard and wired directly to the controller board.

A headset microphone assembly wearable by a patient user is provided to the system for transmitting voice input to said voice recognition means and receiving system command confirmation signals and telephone communications.

Voice – actuated interface
Which accept input and provide output by generating voice prompts. The user is made by pressing keys or buttons, or responding verbally to the interface.

3.1.1 Identify Between Resident And Transient Routines

By
Memory Management Memory management is concerned with managing: The computer’s available pool of memory Allocating space to application routines and making sure that they do not interfere with each other. 3.1.1 Identify between resident and transient routines The operating system is a collection of software routines. Resident routines Transient routines Routines that directly support application programs as they run Stored on disk and read into memory only when needed Example: routine that control physical I/O Example: routine that formats disks The operating system occupies low memory beginning with address 0. Key control information comes first followed by the various resident operating system routines. The remaining memory, called the transient area, is where application programs and transient operating system routines are loaded. Resident & transient routines structure...

Operating Systems Definition and the Classification of OS

By
             OPERATING SYSTEMS ( OS ) What is an operating system? An operating system (sometimes abbreviated as "OS") is the program that, after being initially loaded into the computer by a boot program, manages all the other programs in a computer. The other programs are called applications or application programs. The application programs make use of the operating system by making requests for services through a defined application program interface (API). In addition, users can interact directly with the operating system through a user interface such as a command language or a graphical user interface (GUI). An operating system performs these services for applications:     In a multitasking operating system where multiple programs can be running at the same time, the operating system determines which applications should run in what order and how much time should be allowed for each application before g...

2.1.4 Distinguish between logical I/O and physical I/O

By faizal
2.1.4 Distinguish between logical I/O and physical I/O logical input relate to hard disk Logical I/O an Physical I/O Physical" I/O is an actual fetch of data from a storage device such as a disk. Logical" I/O is a programmatic request for data satisfied by a memory (block, buffer) access. A logical I/O may cause a physical I/O in the first place, or a logical I/O may retrieve a part of a block (buffer) of data from memory. 2.1.5 Distinguish between directory management and disk space management. Directory management A directory is a hierarchical collection of directories and files.  The only constraint on the number of files that can be contained in a single directory is the physical size of the disk on which the directory is located. Disk management A hard disk is a rigid disk inside a computer that stores and provides relatively quick access to large amounts of data. It is the type of storage most often used with Windows. The system also supp...
