Designing for Engagement: Using indirect manipulation to support form exploration in 3D modeling

Serim, Baris January 2012 (has links)
This thesis aims to study the design possibilities for supporting explorative form-finding in 3D modeling applications. For today’s many design professions, 3D forms are achieved partly in engagement with digital environments. Use of software has far exceeded final idea execution, extending to the early phases of design work in which the outcome is not predetermined. This insight led designers of interactive systems support sketching and ideating activities by reducing the risk of experimentation and cognitive effort demanded from user. Yet, there has been less emphasis on traditional design and craft practice that acknowledges engagement with materials and effort spent on work as an integral part of creative process.The notion of exploration in the scope of this thesis attempts to incorporate such aspects. Relevant literature about workshop practice in design and craft has been reviewed, as well as examples of CAD technologies that aid designers. In this light, HCI perspectives on the design of creativity support tools and games have been discussed. The thesis work aimed to concretize this background by building a design strategy and an interactive artifact. A 3D form-finding application concept using objects in modeling space to indirectly manipulate geometry, “kfields”, has been developed and evaluated with users at various stages. The thesis concludes by reflecting on the findings of different design stages and proposing further directions for design.

Reciprocal Explanations : An Explanation Technique for Human-AI Partnership in Design Ideation / Ömsesidiga Förklaringar : En förklaringsteknik för Human-AI-samarbete inom konceptutveckling

Hegemann, Lena January 2020 (has links)
Advancements in creative artificial intelligence (AI) are leading to systems that can actively work together with designers in tasks such as ideation, i.e. the creation, development, and communication of ideas. In human group work, making suggestions and explaining the reasoning behind them as well as comprehending other group member’s explanations aids reflection, trust, alignment of goals and inspiration through diverse perspectives. Despite their ability to inspire through independent suggestions, state-of-the-art creative AI systems do not leverage these advantages of group work due to missing or one-sided explanations. For other use cases, AI systems that explain their reasoning are already gathering wide research interest. However, there is a knowledge gap on the effects of explanations on creativity. Furthermore, it is unknown whether a user can benefit from also explaining their contributions to an AI system. This thesis investigates whether reciprocal explanations, a novel technique which combines explanations from and to an AI system, improve the designers’ and AI’s joint exploration of ideas. I integrated reciprocal explanations into an AI aided tool for mood board design, a common method for ideation. In our implementation, the AI system uses text to explain which features of its suggestions match or complement the current mood board. Occasionally, it asks for user explanations providing several options for answers that it reacts to by aligning its strategy. A study was conducted with 16 professional designers who used the tool to create mood boards followed by presentations and semi-structured interviews. The study emphasized a need for explanations that make the principles of the system transparent and showed that alignment of goals motivated participants to provide explanations to the system. Also, enabling users to explain their contributions to the AI system facilitated reflection on their own reasons. / Framsteg inom kreativ artificiell intelligens (AI) har lett till system som aktivt kan samarbeta med designers under idéutformningsprocessen, dvs vid skapande, utveckling och kommunikation av idéer. I grupparbete är det viktigt att kunna göra förslag och förklara resonemanget bakom dem, samt förstå de andra gruppmedlemmarnas resonemang. Detta ökar reflektionsförmågan och förtroende hos medlemmarna, samt underlättar sammanjämkning av mål och ger inspiration genom att höra olika perspektiv. Trots att system, baserade på kreativ artificiell intelligens, har förmågan att inspirera genom sina oberoende förslag, utnyttjar de allra senaste kreativa AI-systemen inte dessa fördelar för att facilitera grupparbete. Detta är på grund av AI-systemens bristfälliga förmåga att resonera över sina förslag. Resonemangen är ofta ensidiga, eller saknas totalt. AI-system som kan förklara sina resonemang är redan ett stort forskningsintresse inom många användningsområden. Dock finns det brist på kunskap om AI-systemens påverkan på den kreativa processen. Dessutom är det okänt om en användare verkligen kan dra nytta av möjligheten att kunna förklara sina designbeslut till ett AI-system. Denna avhandling undersöker om ömsesidiga förklaringar, en ny teknik som kombinerar förklaringar från och till ett AI system, kan förbättra designerns och AI:s samarbete under utforskningen av idéer. Jag integrerade ömsesidiga förklaringar i ett AI-hjälpmedel som underlättar skapandet av stämningsplank (eng. mood board), som är en vanlig metod för konceptutveckling. I vår implementering använder AI-systemet textbeskrivningar för att förklara vilka delar av dess förslag som matchar eller kompletterar det nuvarande stämningsplanket. Ibland ber den användaren ge förklaringar, så den kan anpassa sin förslagsstrategi efter användarens önskemål. Vi genomförde en studie med 16 professionella designers som använde verktyget för att skapa stämningsplank. Feedback samlades genom presentationer och semistrukturerade intervjuer. Studien betonade behovet av förklaringar och resonemang som gör principerna bakom AI-systemet transparenta för användaren. Höjd sammanjämkning mellan användarens och systemets mål motiverade deltagarna att ge förklaringar till systemet. Genom att göra det möjligt för användare att förklara sina designbeslut för AI-systemet, förbättrades också användarens reflektionsförmåga över sina val.

Imagining the Future of Creative AI Tools : A Cospeculative Workshop

Eriksson, Emelie January 2022 (has links)
Creative artificial intelligence (AI) is often explored in terms of machine intelligence on a philosophical basis. As a counter-reaction, there have been calls for user-centered creative AI. This thesis aims to make visible creative practitioners’ needs, values, and ethical perspectives that might inform us on the construction of future creative AI tools. It also discusses the need for pragmatic aesthetics as a holistic design approach. Five artists of different backgrounds were invited to a co-speculative workshop where they expressed their thoughts and imaginings regarding creativity, creative tools, and AI. The results suggest that we need to be mindful of virtue ethics, N-creativity, exploration, intuition, trust, and agency when designing creative AI tools. Furthermore, the findings were used to propose design sensitivities aimed at AI researchers and designers. Future research is needed in order to make conclusions about the practical value of the proposed design sensitivities. / Kreativ artificiell intelligens (AI) undersöks ofta i termer av maskinintelligens med filosofiska grunder. Som en motreaktion har det förordnats mer användarcentrerad kreativ AI. Denna avhandling syftar till att synliggöra kreativa utövares behov, värderingar och etiska perspektiv som kan informera oss om hur framtida kreativa AI-verktyg bör konstrueras. Den diskuterar även behovet av pragmatisk estetik som en holistisk designstrategi. Fem konstnärer av olika bakgrund deltog i en samspekulativ workshop där de uttryckte sina tankar och föreställningar om kreativitet, kreativa verktyg och AI. Resultaten pekar på att dessa verktyg bör designas med begrepp som dygdetik, N-kreativitet, utforskande, intuition, tillit och datainverkan i åtanke. Vidare användes resultaten för att föreslå designkänsligheter riktade till AI-forskare och designers. Vidare forskning krävs för att kunna dra slutsatser kring designkänsligheternas praktiska nytta.

This research describes a game-based system, Idea Storming Cube, in support of creative thinking. It aims to make people form a creative and Perspective-Modifying thinking habit. Based on theories of this kind support system and prior studies, we propose to integrate exciting game environment and intelligent support mechanism into the creativity thinking support system. The system acquires knowledge from domain expert, user inputs history, and individuals of a brainstorming group, and then provides user-, goal- and context-sensitive supports. Compared to classic tutoring systems, it focuses more on stimulating divergent thinking. The system can be utilized with two distinct support strategies, Basic Mode and Agent-Assist Mode, in order to support different learning objectives. One focus on knowledge learning, the other highlights the divergent thinking ability. The proposed Human-Computer Interaction (HCI) tool for collaborative idea generation has been implemented, and two experiments for preliminary evaluation of the system are also reported in this thesis. The major results of this study show that the game-based brainstorming system with appropriate intelligent support outperforms the other types of systems because the game competition environment can make them concentrate on the brainstorming tasks and let them think more from different view points for learning the knowledge with the support of the peer-like agent.
