Abstract
The manufacture of prototypes is costly in economic and temporal terms and in order to carry this out it is necessary to accept certain deviations with respect to the final finishes. This article proposes haptic hybrid prototyping, a haptic-visual product prototyping method created to help product design teams evaluate and select semantic information conveyed between product and user through texturing and ribs of a product in early stages of conceptualization. For the evaluation of this tool, an experiment was realized in which the haptic experience was compared during the interaction with final products and through the HHP. As a result, it was observed that the answers of the interviewees coincided in both situations in 81% of the cases. It was concluded that the HHP enables us to know the semantic information transmitted through haptic-visual means between product and user as well as being able to quantify the clarity with which this information is transmitted. Therefore, this new tool makes it possible to reduce the manufacturing lead time of prototypes as well as the conceptualization phase of the product, providing information on the future success of the product in the market and its economic return.
Highlights
Consumers’ lifestyles are continually changing and demand that new products come onto the market more frequently [1]
The studied attributes were evaluated with respect to the degree the deviation of the results was ±1 on a weighting of 5 points
An overall analysis of the results shows that the deviation of ±3 and ±4 is reduced in comparison to to the responses that present a greater similarity
Summary
Consumers’ lifestyles are continually changing and demand that new products come onto the market more frequently [1]. This, together with the challenge posed by the paradigm of Industry 4.0 (I 4.0) at present, makes tools such as augmented reality (AR) have the purpose of promoting autonomous interoperability, agility, flexibility, rapid decision-making, efficiency, and cost reduction [3,4,5] Within this framework, one of the main purposes of design engineering teams is to focus on the user to meet their needs and expectations [6,7]. In the conceptual phase, the correct formal, functional and aesthetic adaptation of the product by industrial designers is crucial to avoid problems in the following phases of the design process or even market products with erroneous attributes [8] For this reason, during the product conceptualization process, it is crucial to predict at an early stage during the design phase the future reactions of users to the product [9].
