DIGITAL FRIDGE CASE STUDY

Digital Fridge case study



Digital Fridge case study

Introduction

In order to avoid repeating their competitors' flop, this report will seek to review literature and standards in order to frame the approach being taken in a critical perspective. Following this, the report will model user and usage scenarios while identifying (and justifying) which main functional and non-functional requirements the system should fulfil. The report will also suggest any significant usable feature of its GUI (graphical user interface), supported by some screenshots or sketched drawn samples to further clarify your statements.

Current Principles and Approaches

Competitors have employed various approaches in accordance with the principles of HCI (human computer interface) set by International Standard Organization. The current principles set by ISO deals with the modelling of such intelligent devices which are portable and light-weight and consumer / customer can easily use the current approaches. This should possess no harm in many means to the mental and physical health of the consumer / customer.

My proposed approach

In the process of doing so, the paper will aim to acquire an understanding of the complex factors that contribute to an effective design, and the tools and techniques for creating interactive systems, the range of domains in which interactive systems operate and the impact of the domain on the design process. This will enable the development of an informed choice amongst the concepts, tools and techniques available for the design of interactive systems and design interactive systems in specified domains taking into account relevant standards, guidelines and legislation.

User and usage scenarios

There is a wide range of options that the Digital Fridge will seek to provide the user with. However, every time a user visits the Digital Fridge, he/she can be expected to engage in any one of the following three tasks. It merits highlighting at this point that these processes are only skeletal representations meant to provide the DF requirement engineers with a representation of the Digital Fridge's abilities and is not meant to recommend a limitation of the Digital Fridge's abilities.

Process 1: A new item can be added to the stored items.

Start process: Item added

Detect shelf in which new item has been added

Take inputs from user

Nature of new item

Preferred expiry date of item

Close process: Thank user

Process 2. Already stored item can be used and placed back in the Digital Fridge again.

Start process: detect the shelf on which the item was placed and has been placed back again.

Take inputs from user

Confirm if used item has been replaced back or new item has been placed.

If new item has been placed then move to process 1

If already stored item has been used and placed back in the Digital Fridge again then confirm if user would like to continue with the item's expiration date.

If user answers in positive then move to close process. If user answers in negative then ask user to enter preferred expiry date of item.

Close process: Thank user

Process 3. A stored item can be removed from the Digital ...
