We offer a definition of haptic experience (HX), the user experience particular to haptic technologies, and a model for both experiential dimensions and usability requirements for creating a good haptic experience. Haptic technology is maturing, with expectations and evidence that it will contribute to user experience (UX). However, we have…

Autonomous vehicles have been rapidly progressing towards full autonomy using fixed driving styles, which may differ from individual passenger preferences. Violating these preferences may lead to passenger discomfort or anxiety. We studied passenger responses to different driving style parameters in a physical autonomous vehicle. We collected galvanic skin response, heart…

We studied how novice hapticians - engineers and designers with little haptics experience - designed multisensory haptic experiences, and through their successes and challenges, found out more about the haptic experience design process: design choices, activities, and success strategies. Access to haptic technology is on the rise, in smartphones, virtual…

DualPanto is a haptic device that enables blind users to track moving objects while acting in a virtual world. As shown in above figure (b), the device features two handles. Users interact with DualPanto by actively moving the me handle with one hand and passively holding on to the it…

(Project led by Alexandra Ion) We present metamaterial textures—3D printed surface geometries that can perform a controlled transition between two or more textures. Metamaterial textures are integrated into 3D printed objects and allow designing how the object interacts with the environment and the user’s tactile sense. Inspired by…

Haptic Experience Design (HaXD), the process of designing for touch, is extremely challenging but poorly understood. We interviewed professional hapticians to develop a first description of HaXD, identify critical barriers to design, and several recommendations for future support tools. Paper: PDF IJHCS Summary From our research we define HaXD as:…

(with UBC SPIN lab) Morphing - combining two pieces of media into a third in-between one - is a powerful technique for creative control over images and audio. Can the same work for the sense of touch? We developed a new algorithm based on dynamic-time warping to morph rhythm profiles…

Collaborators: Paul Bucci, David Marino, Laura Cang, Karon MacLean As robots enter our daily lives, they need to communicate believably, that is, emotionally and on human terms. When physical agents gesture, touch, and breathe, they help humans and robots work together, and even lead to applications like robot-assisted therapy. However,…

Physical action, like playing with springs, interacting with tangibles, or moving your body, can help students learn. Meanwhile, online learning has increased accessibility, connecting students to resources around the globe. How can we connect these two benefits? Haptic technology could enable programmable, online, physical learning, but needs accessible hardware and…

How do we crowdsource haptics? Platforms like Amazon's Mechanical Turk have enabled rapid, large-scale feedback for text, graphics, and sound. Designers can collect impressions in minutes; researchers run experiments within hours. But sending haptic devices out at such a scale is infeasible. We use two proxy modalities to convey affective…

Examples can help the design process, but haptic libraries are limited: they are opaque & immutable. We explore the potential for visualized, editable examples in vibrotactile design. Using a new web-based editor, Macaron, as our platform, we establish a picture of vibrotactile design with examples. We find additional access can…

Touchscreens have revolutionized how we provide information to computers, but they provide little physical feedback. As part of the first haptics Student Innovation Challenge, we set out to find how touchscreens can feel with a drawing application. We used the TPad Phone, which vibrates its screen at high-frequencies to programmatically…

Haptic Experience Design (HaXD) is difficult. We need to develop processes, tools, and vocabulary to better support designers when working with haptics. At World Haptics 2015, we ran a workshop to help develop HaXD by discussing existing practices, identifying challenges, and brainstorming potential solutions. Four speakers from industry and academia…

Mobile devices have imbued asynchronous messaging with rich media content. Images, video, and audio can now be sent at a moment’s notice, but this excludes the sense of touch. We introduce Feel Messenger, a messaging app for commercial smartphones that supports customized vibrotactile sensations. Feel Messenger employs Feel Effects,…

Collaborators: Ali Israr, Siyan Zhao Tactile interactions can make movies, games, and other media more engaging, but there's no support for physical feedback in current media types. FeelCraft is a new way to add touch-based feedback to any media type. We use a library of general tactile effects ("Feel Effects"…

Haptic (touch-based) technology is becoming more prevalent, from vibrations in smartphones to novel gaming devices. Unfortunately, haptic designers do not have the same tools available to them as graphic or audio designers. The Haptic Jazz project improves matters by offering designers a new tool inspired from musical instruments - the…

Smartphones have a wealth of sensors in them. As part of my master's work, I helped develop algorithms that use smartphone accelerometers to measure information about gait (how a person walks). We've developed the RRACE algorithm that can sense a user's cadence (step frequency) without any training on the person.…

Flexible display technology opens up a world of possibilities for novel interaction techniques. We asked, could life-like movement be used by smartphones to communicate information to users? We found that gestural displays were a powerful way to connect with users, especially to convey emotional information. (paper) Collaborators: Jessica Dawson, Joel…

The muscle spindle is one of the major organs that provides us with the sense of proprioception, or body location - it's how we know a heavy weight from a light one when working out at the gym. I've taken a computational model of the muscle spindle, implementing it in…

End-User License Agreements (EULAs) are infamous for being unreadable, but still can hold up in court. ConsentCanvas is an open-source system that uses natural language processing (NLP) techniques to structure and "texturize" EULAs to improve readability. This work was inspired by Kay & Terry's initial idea of Texturized Agreements. (Paper)…

Computer-based disease modeling can help epidemiologists track diseases and inform policy, but models can be challenging to understand for non-expert programmers. Frabjous (Functional Reactive Agent-Based Simulation) is a domain-specific language and programming framework that uses the novel approach of functional reactive programming (FRP) to make models more understandable. (paper) Collaborators:…

PythNon is a cross-platform problem-solving environment (PSE) designed to aid students and researchers when solving nonlinear algebraic expressions. Oliver's role was to improve the user interface through protyping, user studies, and HCI design principles. He was also involved in programming these changes, revising documentation, and doing final deployment packaging. (software)…

Dynamic audio synthesis can be used to improve groupware awareness in real-time collaborative groupware, especially when visual channels are cluttered or limited. GTBlackboard is a fully shared blackboard application that procedurally generates graphics and audio. It runs on Windows XP, Vista, and 7 using the .NET Framework. (paper) (software) Collaborators:…
