-Overcrowded shops and the time spent doing shopping are major issues that have been affecting the shopping experience of consumers worldwide. The majority of people shop for groceries in person, at a physical grocery store while only 16% of surveyed ((grocerystatistics))  get their groceries delivered. Overcrowding in shops refers to a situation where there are too many people in a store, making it difficult for shoppers to move around, shop comfortably, or maintain social distancing, especially during peak periods such as holidays or weekends. This can lead to frustration, anxiety, and dissatisfaction with the shopping experience.+Overcrowded shops and the time spent doing shopping are major issues that have been affecting the shopping experience of consumers worldwide.

This can lead to frustration, anxiety, and dissatisfaction with the shopping experience.
 In addition to overcrowding, the time spent doing shopping is also a significant issue for consumers. ((grocerystatistics)) The majority of people spend less than 44 minutes grocery shopping per trip. With busy schedules and limited time, many shoppers find themselves spending more time than they would like to complete their shopping, resulting in inconvenience, stress, and reduced productivity. This can be due to factors such as long queues at the checkout, difficulty finding products, or insufficient staff to assist shoppers. In addition to overcrowding, the time spent doing shopping is also a significant issue for consumers.

 With our smart supermarket (FESmarket) we would like to find a solution to those problems and make the process of buying groceries an easy, quick, and enjoyable task. With our smart supermarket (FESmarket) we would like to find a solution to those problems and make the process of buying groceries an easy, quick, and enjoyable task.

-Haptic technology ensures not only communication but attempts to provide the user with an immersive interactive experience. It is the idea of incorporating touch into the digital world. There are three types of categories that devices fall into in regards to haptic technology—graspable (e.g., a joystick), wearable (e.g., a finger pad put on your finger) and touchable (e.g., smartphones or smart watches) (Hutson, 2018). This idea of touch entering into technology has reached several fields beyond the screen. Such fields that have taken interest include medicine, robotics and even art (Hutson, 2018; De Venecia, 2020; Haptic technology. n.d.). While we will focus on how haptics interact with us on a daily basis, haptics is changing the way we interact with future technology [(Syndey2020)].\\+Haptic technology ensures not only communication but attempts to provide the user with an immersive interactive experience.

 Introducing haptic feedback for customers in a smart shopping cart might exchange the user experience. Supermarkets are big, crowded and are built to make one lose focus because of the different colours and varieties of products displayed.  Introducing haptic feedback for customers in a smart shopping cart might exchange the user experience.

 Overall, the report concludes that Gen Z and millennial shoppers care about similar things when grocery shopping. First and foremost is convenience. Also important are loyalty programs, food samples, grocery store apps, an improved online shopping experience, and quality of personnel. These attributes apply both in-store and online, which indicates shoppers prefer an omnichannel experience. “Retailers that can successfully develop and implement omnichannel strategies will have an excellent opportunity to increase customer satisfaction, loyalty, and retention rates,” FMI notes [(FoodIndustry2020)]. Overall, the report concludes that Gen Z and millennial shoppers care about similar things when grocery shopping.
