This paper discusses the use of participant-generated drawings and drama workshops as user experience research methods. In spite of the lack of background literature on how drawings can generate useful insights on HCI issues, drawings have been successfully used in other research fields. On the contrary, drama workshops seem to be increasingly popular in recent participatory design research. After briefly introducing such previous work, three case studies are presented, illustrating the use of drawing and drama workshops when investigating the relationship between media technology users and two specific devices, namely televisions and mobile phones. The paper focuses on the methods and discusses their benefits and the challenges associated with their application. In particular, the findings are compared to those collected through a quantitative cross-cultural survey. The experience gathered during the three case studies is very encouraging and calls for additional reports of UX evaluations involving drawingand theatre-based exercises.

Tangelo (https link) is an open-source Python software package for the development of end-to-end chemistry workflows on quantum computers, released under Apache 2.0 license. It aims to support the design of successful experiments on quantum hardware, and to facilitate advances in quantum algorithm development. The software enables quick exploration of different approaches by assembling reusable building blocks and algorithms, with the flexibility to let users introduce their own. Tangelo is backend-agnostic and enables switching between various backends (Braket, Qiskit, Qulacs, Azure Quantum, QDK, Cirq...) with minimal changes in the code. The package can be used to explore quantum computing applications such as open-shell systems, excited states, or more industrially-relevant systems by leveraging problem decomposition at scale. This paper outlines the design choices, philosophy, and main features of Tangelo.

As ubiquitous media is developing rapidly, new HCI challenges emerge. In this paper, we address usability issues related to the transfer of content between fixed and mobile devices, as well as channel switching delays on mobile devices. We first provide an extensive review of the field. We then evaluate four relatively novel approaches for initiating a transfer of video content from a mobile phone to a TV screen. Seen from a user's point of view, familiarity and comfort are found to be important decision factors when selecting a preference among the proposed methods. Furthermore, we identify a threshold level above which people appear to be annoyed when switching between TV channels on a mobile device, and investigate factors that may influence the perceived acceptability of such delay.
