We propose a tangible interface concept for communicating personal financial information in an ambient and relevant manner. The concept is embodied in a set of wallets that provide the user with haptic feedback about personal financial metrics. We describe how such feedback can inform purchasing decisions and improve general financial awareness.
We examined the effect of endogenous free fatty acids (FFA) on the measurement of free thyroxin (FT4) by five different methodologies represented in 16 different assays in a large number of patients with nonthyroidal illness (NTI). Some, but not all, one-step (analog) FT4 RIAs negatively correlated with FFA concentration. All two-step FT4 RIAs, equilibrium(More)
The rate of the Jaffé reaction depends on the concentration of sodium hydroxide; the pseudo-first-order rate constant of the reaction, at 37 degrees C in 10 mmol/L picrate solution, is 0.004 mmol/L. We formulated an automated method to determine urinary creatinine directly without manual sample dilution. The conditions are as follows: 10 mmol/L picrate and(More)
We describe a practical vision of ubiquitous computing with tangible interfaces, that orbits around an individual and is mediated by his or her personal consumer electronic devices. We illustrate this with a software and hardware platform for creating a personal area network of information accessories, connecting people physically with network-accessible(More)
