user interfaces often only support one way to do a task when the physical interface or the requirements of the task would permit other ways. In contrast, a user interface that supports multiple approaches is permissive. This paper argues that permissive user interfaces are easier to use-and even when they are not applicable for particular applications, considering permissiveness is a productive design heuristic. Many user interfaces are difficult to use yet very easily demonstrated or explained by experts-with the results that users become frustrated because hindsight makes usability problems look like the user's own fault. The lack of permissiveness in such user interfaces explains this paradox. (C) 2001 Academic Press.

Software Refactoring Process to Accommodate user-interface Adaptivity in Existing Applications

INTERACTING WITH COMPUTERS 2013年第6期25卷 461-484页

Adaptive user-interfaces are capable of: (a) composing themselves at runtime according to a given deployment profile typically encompassing user and usage-context information and (b) possibly dropping user-interface components and activate better alternatives in their place in response to dynamic profile modifications. While adaptive behavior increasingly gains interest for a wide range of software products and services, its support is very demanding requiring adoption of user-interface architectural patterns from the very early software design phases. While previous research addressed the issue of engineering adaptive interactive applications right from scratch, there is an important methodological gap as we lack processes for the systematic evolution of existing non-adaptive applications to adaptive ones. We present a stepwise transformation process of the user-interface source code by incrementally upgrading all relevant implementation structures towards user-interface adaptivity. Because all transformation actions have been chosen to be standard refactorings the conduct of the process is well-defined while adoption preserves the original application architecture and quality of the source code.

Ontology-Based Application Integration on the user interface Level

IT-INFORMATION TECHNOLOGY 2013年第4期55卷 165-168页

Application integration can be performed on three levels: the data source level, the business logic level, and the user interface level. Approaches of the latter kind include, e.g., portal and mashup solutions. Deeper integration offering rich interaction possibilities usually leads to strong dependencies between applications, and requires deep knowledge of those applications. To reduce such dependencies, ontologies have been proposed as an inter-lingua mediating between the applications. While there have been approaches for using ontologies for integration on the data source and business logic level, this dissertation is the first approach for ontology-based application integration on the user interface level. It discusses the development of suitable formal ontologies, the use of reasoning and rule-based event processing, as well as aspects such as performance and seamless cross-technological interaction.

A typical way to design and develop a mobile app is to sketch the graphical user interfaces (GUIs) for the different screens in the app and then create actual GUIs from these sketches. Doing so involves identifying which layouts to use, which widgets to add, and how to configure and connect the different pieces of the GUI. To help with this difficult and time-consuming task, we propose GUIFetch, a technique that takes as input the sketch for an app and leverages the growing number of open source apps in public repositories to identify apps with GUIs and transitions that are similar to those in the provided sketch. GUIFetch first searches public repositories to find potential apps using keyword matching. It then builds models of the identified apps' screens and screen transitions using a combination of static and dynamic analyses and computes a similarity metric between the models and the provided sketch. Finally, GUIFetch ranks the identified apps (or parts thereof) based on their computed similarity value and produces a visual ranking of the results together with the code of the corresponding apps. We implemented GUIFetch for Android apps and evaluated it through user studies involving different types of apps.

Virtual Reality is gaining popularity due to the gaming industry. But there are many other applications of VR like training, rehabilitation, and simulation. This is our effort to combine all these application to create a technique for assessing return-to-play readiness in athletes with concussions using Virtual Reality (VR). The subjects perform various Soccer related simulations. By measuring their responses during the execution of these tasks we can asses their ability to return to the game.

A new approach to programming computing machinery is presented, representing programming without a written software artifact-a program. The availability of numerous speech-to-text services, gives access to practical voice recognition. Enguage TM is an open, programmable speech understanding engine, prototyped in Java, which is built into an app on Google Play, acting entirely as its user interface. Thus, devices can be instructed, and present results, in natural language utterances;engineers are afforded their own concepts and associated conversations. This paper shows how this can be turned in on itself, programming the interpretation of utterances, itself, purely through utterance.

This work explores the use of foot gestures for locomotion in virtual environments. Foot gestures are represented as the distribution of plantar pressure and detected by three sparsely-located sensors on each insole. The Long ShortTerm Memory model is chosen as the classifier to recognize the performer's foot gesture based on the captured signals of pressure information. The trained classifier directly takes the noisy and sparse input of sensor data and identifies seven categories of foot gestures (stand, walk forward/backward, run, jump, slide left and right) without the manual definition of signal features. This classifier is capable of recognizing the foot gestures, even with the existence of large sensor-specific, inter-person and intra-person variations. Results show that an accuracy of 80% can be achieved across different users with different shoe sizes and 85% for users with the same shoe size. A novel method, Dual-Check Till Consensus, is proposed to reduce the latency of gesture recognition from 2 seconds to 0.5 seconds and increase the accuracy to over 97%. This method offers a promising solution to achieve lower latency and higher accuracy at a minor cost of computation workload. The characteristics of high accuracy and fast classification of our method could lead to wider applications of using foot patterns for human-computer interaction.

In recent years, virtual reality (VR) based training has greatly changed surgeons learning mode. It can simulate the surgery from the visual, auditory, and tactile aspects. VR medical simulator can greatly reduce the risk of the real patient and the cost of hospitals. Laparoscopic cholecystectomy is one of the typical representatives in minimal invasive surgery (MIS). Due to the large incidence of cholecystectomy, the application of its VR-based simulation is vital and necessary for the residents' surgical training. In this paper, we present a VR simulation framework based on position-based dynamics (PBD) for cholecystectomy. To further accelerate the deformation of organs, PBD constraints are solved in parallel by a graph coloring algorithm. We introduce a bio-thermal conduction model to improve the realism of the fat tissue electrocautery. Finally, we design a hybrid multi-model connection method to handle the interaction and simulation of the liver-gallbladder separation. This simulation system has been applied to laparoscopic cholecystectomy training in several hospitals. From the experimental results, users can operate in real-time with high stability and fidelity. The simulator is also evaluated by a number of digestive surgeons through preliminary studies. They believed that the system can offer great help to the improvement of surgical skills.

Animating with keyframes gives animators a lot of control but they can be tedious and complicated to work with. Currently, different solutions try to simplify animation creation by recording the natural hand movements of the user. However, most of the solutions are bound to 2D animations [1] or suffer from a low workflow speed [4]. The proposed Unity plugin AnimationVR uses the HTC Vive system to enable the puppeteering animation technique in VR while still allowing for a fast workflow speed by utilizing the 6DOF controllers. During storyboarding or rapid prototyping, the user can immediately see the results of their actions. Also, AnimationVR is written for easy integration in already existing Unity projects. The plugin was evaluated by four animation experts who agreed that AnimationVR accelerates the workflow while decreasing the animation precision. This trade-off makes it useful for storyboarding in professional environments. The experts also noted the ease of use of the puppeteering technique which could enable beginners to create complex animations without any experience with animating.

Spatial computing could change our interaction with the physical world, yet development tools still largely apply to outdated methods, representing 3D objects with 2D text in code editors. This discrepancy makes the programming of spatial applications more complicated. PhyOOP, our Physical Object-Oriented programming Environment, trying to solve this issue by capturing object states through camera feeds for direct code insertion and attaching executable snippets to objects for camera-triggered actions. The user study, involving 16 participants, suggests that PhyOOP is easy-to-use and has potential applications in various domains.
