We present an interactive tool to animate the visual elements of a static picture, based on simple sketch-based markup. While animated images enhance websites, infographics, logos, e-books, and social media, creating such animations from still pictures is difficult for novices and tedious for experts. Creating automatic tools is challenging due to ambiguities in object segmentation, relative depth ordering, and non-existent temporal information. With a few user drawn scribbles as input, our mixed initiative creative interface extracts repetitive texture elements in an image, and supports animating them. Our system also facilitates the creation of multiple layers to enhance depth cues in the animation. Finally, after analyzing the artwork during segmentation, several animation processes automatically generate kinetic textures [27] that are spatio-temporally coherent with the source image. Our results, as well as feedback from our user evaluation, suggest that our system effectively allows illustrators and animators to add life to still images in a broad range of visual styles.

Mavo is a small extension to the HTML language that empowers non-programmers to create simple web applications. Authors can mark up any normal HTML document with attributes that specify data elements that Mavo makes editable and persists. But while applications authored with Mavo allow users to edit individual data items, they do not offer any programmatic data actions that can act in customizable ways on large collections of data simultaneously or that modify data according to a computation. We explore an extension to the Mavo language that enables non-programmers to author these richer data update actions. We show that it lets authors create a more powerful set of applications than they could previously, while adding little additional complexity to the authoring process. Through user evaluations, we assess how closely our data update syntax matches how novice authors would instinctively express such actions, and how well they are able to use the syntax we provided.

Aalto interface Metrics (AIM) pools several empirically validated models and metrics of user perception and attention into an easy-to-use online service for the evaluation of graphical userinterface (GUI) designs. users input a GUI design via URL, and select from a list of 17 different metrics covering aspects ranging from visual clutter to visual learnability. AIM presents detailed breakdowns, visualizations, and statistical comparisons, enabling designers and practitioners to detect shortcomings and possible improvements.

In this paper, we proposed improvements to the Human Computer Interaction in serious contents using Leap Motion and VR HMD. user immersion and interaction could be the core of VR contents technology. Recently, the advance of VR HMD technology is getting attention in VR contents market. Currently used interface methods are mostly uncomfortable for users since the way of interaction stems from the conventional interface layout rather than considering the physical characteristics of VR HMD. To achieve this, the HUD (Head-Up Display) has been used to optimize the interaction of a serious VR content that is suitable for VR HMD and Leap Motion. In addition, to validate the proposed study, we show the comparison of performance tests.

End-user elicitation studies are a popular design method, but their data require substantial time and effort to analyze. In this paper, we present Crowdsensus, a crowd-powered tool that enables researchers to efficiently analyze the results of elicitation studies using subjective human judgment and automatic clustering algorithms. In addition to our own analysis, we asked six expert researchers with experience running and analyzing elicitation studies to analyze an end-user elicitation dataset of 10 functions for operating a web-browser, each with 43 voice commands elicited from end-users for a total of 430 voice commands. We used Crowdsensus to gather similarity judgments of these same 430 commands from 410 online crowd workers. The crowd outperformed the experts by arriving at the same results for seven of eight functions and resolving a function where the experts failed to agree. Also, using Crowdsensus was about four times faster than using experts.

This paper presents Mindgame, a reinforcement learning optimized neurofeedback mindfulness system. To avoid the potential bias and difficulties of designing mapping between neural signal and output, we adopt a trial-and-error learning method to explore the preferred mapping. In a pilot study we assess the effectiveness of Mindgame in mediating people's EEG alpha band. All participants' alpha band change towards the desired direction.

Advanced Driver Assistance Systems (ADAS) come equipped on most modern vehicles and are intended to assist the driver and enhance the driving experience through features such as lane keeping system and adaptive cruise control. However, recent studies show that few people utilize these features for several reasons. First, ADAS features were not common until recently. Second, most users are unfamiliar with these features and do not know what to expect. Finally, the interface for operating these features is not intuitive. To help drivers understand ADAS features, we present a conversational in-vehicle digital assistant that responds to drivers' questions and commands in natural language. With the system prototyped herein, drivers can ask questions or command using unconstrained natural language in the vehicle, and the assistant trained by using advanced machine learning techniques, coupled with access to vehicle signals, responds in real-time based on conversational context. Results of our system prototyped on a production vehicle are presented, demonstrating its effectiveness in improving driver understanding and usability of ADAS.

We present GridDrones, a self-levitating programmable matter platform that can be used for representing 2.5D voxel grid relief maps capable of rendering unsupported structures and 3D transformations. GridDrones consists of cube-shaped nanocopters that can be placed in a volumetric 1xnxn midair grid, which is demonstrated here with 15 voxels. The number of voxels and scale is only limited by the size of the room and budget. Grid deformations can be applied interactively to this voxel lattice by manually selecting a set of voxels, then assigning a continuous topological relationship between voxel sets that determines how voxels move in relation to each other and manually drawing out selected voxels from the lattice structure. Using this simple technique, it is possible to create unsupported structures that can be translated and oriented freely in 3D. Shape transformations can also be recorded to allow for simple physical shape morphing animations. This work extends previous work on selection and editing techniques for 3D userinterfaces.
