Calibration and Accuracy Testing of Mobile Phone Cameras

This paper examines the potential of mobile phones to be used as a front-end sensor for photogrammetric procedures and applications. For this purpose we are currently calibrating various mobile phones over our indoor 3D testfield, using self-calibration. Using the same testfield we are performing accuracy tests in order to evaluate the metric performance. This paper reports about first experien...

New insights into compliance with a mobile phone diary and pedometer use in sedentary women.

OBJECTIVES The purposes of this study were 1) to determine compliance with a pedometer and mobile phone- based physical activity diary, and 2) to assess concordance between self-reported daily steps recorded and transmitted by a mobile phone and pedometer-measured daily steps in sedentary women. METHODS In this 3-week pilot clinical study, 41 sedentary women who met all inclusion criteria wer...

Detection of falls using accelerometers and mobile phone technology.

OBJECTIVES to study the sensitivity and specificity of fall detection using mobile phone technology. DESIGN an experimental investigation using motion signals detected by the mobile phone. SETTING AND PARTICIPANTS the research was conducted in a laboratory setting, and 18 healthy adults (12 males and 6 females; age = 29 ± 8.7 years) were recruited. MEASUREMENT each participant was request...

Fundamentals of Technology Diffusion and Mobile Phone Case Study*

The fundamentals of technology diffusion are introduced in this paper. Mathematical and heuristic (loose) modeling are defined and illustrated with real data. Starting with the embryonic phase, diffusion undergoes growing and mature phases and ends in the aging phase. The cumulative adoption function (of time) denoting the total number of users of a certain product is the output of the diffusio...
