UX Factors To Consider In The Point Of Sale System Design
If you want to design the best e-POS software, you may face with a unique set of challenges that will arise due to the unique context that is software is associated with as well as the purpose of its use. Below in this article, we will cover the UX Factors To Consider In The Point Of Sale System Design.
As a UX designer you will need to consider several factors regarding user experience and at the same time conduct a few user research activities. These researches will enable you to understand:
- How the users use the e-POS software systems
- How the user experience is affected
- What is your job to produce the best user experience and
- How a few of them helps the user to be proficient its use and have a better user experience?
Since the context is different in many ways, you may not find it easy or possible to implement the standard UX agencies design pattern readily into an e-POS software app, irrespective of whether it is a solution for web-based, iOS, or Android devices.
The context issues
The context issues are very prominent in the e-POS design along with its setting and the way in which the users use the e-POS system. This is because, this app is completely different from any other tablet app, especially when it comes to its usage. Here it is how:
- Distance to screen: Tablets, phones, and laptops are movable gadgets and most of the times, people hold these at a distance of at least 40 cm as this is the most comfortable distance to see everything clearly. The usability of the standard apps depends largely on the sizes of fonts, buttons and its placements but for POS software, these conditions do not apply. It is found through several onsite types of research that the real settings and results with a POS software when it comes to the distance to the screen factors is usually at least double than that. This is even when the position of the POS system can be controlled.
- Time pressure: Most apps claim that it is very easy to use and in most of the times, it is translated to their marketing slogans. They advertise speed and usability, but the fact is that users usually go through the user flows at their own sweet pace and never really feel the time pressure. However, the POS system users do have this luxury. They have to get engaged with the e-POS interface as quickly as possible to backlog and queues from forming. That means the users of the POS system will be under constant time pressure and will have to tap their fingers at double speed as compared with the normal users. In order to deal with the pressures from the consumers which is real, you will have to be intuitive and coherent to create a more reliable User Experience Design for the e-POS user interface.
- Physicality: The physicality of the e-POS software must reach a whole new standard. This standard should be very high as compared to any standard apps because the user experience of the POS software is not purely digital. In fact, it is a part of a much larger setting. This is the physical aspects of it that include the space around the counter, the shape, the size of the product, the layout, the scanner, other third-party devices, the card reader and others.
Ideally, the POS system should be the node that will connect all these elements to provide the best user experience. That is why the designers must understand the real-life context and take everything into account for designing the POS interface design. Furthermore, the designers must also make it a point that they do not underestimate the large variety of conditions and configurations. All these are the most important physical factors that will manifest where the POS system will be used.
The user factors
When you are done with the context issues, it is time to focus on the user factors. Any design approach involves consideration of the user experience and all designers should be mindful about the limitations of the users. When it comes to a POS system, there may be a variety of people who will operate it and therefore it is significant that you pay attention to these factors.
- Attention: Most users have remarkable and considerable control over their attention even though they do a couple of things while they use an app. Users of the POS system will have to engage with the customer both verbally as well as visually and at the same time be well aware of the larger context of the store. This will make the experience very pleasant and more personal. For them switching attention is an executive function and it can be very taxing and tiring on their cognitive abilities.
- Visual impairment: User experience designers always design their product keeping in mind that about 5% of the total users may have mild visual impairment of some kind due to several external reasons.
General users can handle these issues easily, but the designers must design an interface that will much more be accommodating for the needs of the visually impaired.
The design principles
As far as the design principles of the POS systems are concerned, the designers need to keep in mind the:
- Left and right-handedness of the users and determine how the content interrelates with the hand gestures as well as the positioning of the system
- Process constraints as business goals can be much different from the user goals and
- Misconduct that will not only result in a monetary loss but will also create an accounting mess and therefore create a design that will discourage it.
All these little efforts will affect the speed, value and trust of the product designed. The design will also be free from any errors and everything will be integrated in the most thoughtful way. An error-free design will help in the accounting process as well as the proficiency of the user in a real-life setting. Therefore, the interface design must be subtle in both ways, using the POS software and supporting the users.
