Human Computer Interaction

We believe that the existing 802.11 standards can be optimized (especially in terms of energy-efficiency) to make Wi-Fi suitable for a wide range of IoT applications.

Touché proposes a novel Swept Frequency Capacitive Sensing technique that can not only detect a touch event, but also recognize complex configurations of the human hands and body.

We present a new tongue input device, the tongue joystick, for use by an actor inside an articulated-head character costume.

We present a new technology for enhancing touch interfaces with tactile feedback. The proposed technology is based on the electrovibration principle, does not use any moving parts and provides a wide range of tactile feedback sensations to fingers moving across a touch surface.

We present a tactile-rendering algorithm for simulating 3D geometric features, such as bumps, on touch screen surfaces. This is achieved by modulating friction forces between the user’s finger and the touch screen, instead of physically moving the touch surface.

Surround Haptics is a new tactile technology that uses a low-resolution grid of inexpensive vibrating actuators to generate high-resolution, continuous, moving tactile strokes on human skin [1]. The user would not feel the discrete tactile pulses and buzzes that are so common today, but rather a smooth tactile motion, akin to what we feel when someone drags a finger across our skin.

In this paper we present the design and evaluation of a two dimensional haptics display intended to be used for enhancing experience for movies and rides.

In this paper, we present three experiments to measure the control parameter space of apparent haptic motion using variety of stimulation attributes and body sites.

Tactile Brush is an algorithm that produces smooth, two-dimensional tactile moving strokes with varying frequency, intensity, velocity and direction of motion.

In this paper we explore the possibilities for this vision afforded by fabrication of custom optical elements using today’s 3D printing technology.
