AB  - WIP: iOS® Devices as DAQ and hardware for experiments in class to        enhance the real touch, feel and see experiencesReal touch, feel and see experiences are very important aspects for mostengineers to gain deeper understanding. For this primary reason, educationalinstitutions in the past several decades have always included laboratoryexperiments as part of the undergraduate curriculum. The experiments built the“gut instinct” for many of the engineers as part of their educational experience,which has proved useful in their professional career.Real touch, feel and see experiences are provided by experiments inlaboratories. Laboratories in general are expensive, occupy real estate that donot find alternate uses and naturally become the primary targets for costreduction in most colleges and universities. With the advent of computers andtheir increased capability of generating realistic simulations as substitutes forlaboratories, administrators of colleges and universities found a justification foreliminating laboratories. In fact most ABET approved programs in the countryhave far fewer laboratories in their recommended academic plans than they did afew years ago. The reduction or elimination of real touch, feel and seeexperiences of laboratories have in general contributed to the loss of “gutinstinct” for many engineers.Using the increasingly common smart phone with cost effective hardware,experiments have been designed to bring back some of the touch, feel and seeexperiences to the classroom. Almost every smart phone on the market has twosensors that can be used for creating in class experimental experience; agyroscope and an accelerometer. This work in progress (WIP) has utilized thesesensors and developed experiments and apps for download for any student orteacher to use as part of their education. Figure 1. shows the accelerationrecorded for a single experiment.As part of this WIP, an app has been developed to gather the raw data of thesensors as shown in figure 2. An option to record the data or the graph data hasbeen provided. Once the data is gathered the data can be e-mailed, or uploadedto another device via Bluetooth. Past experiment data is stored using the dateand time format currently. (see figure 3) Exported data from the experiment canbe processed and graphed using Excel (see figure 4) or Matlab or any othersoftware.Currently experiments to study linear acceleration, spring-mass-damper systems,and pendulum motion have been developed and are undergoing tests andevaluation. Experiments make use of a toy car for a mobile platform, rubberbands, hooks, a rigid bar of known mass and properties, etc. along with phoneapps. Most smart phones SDK (System Development Kit) provide access tocurrent and future sensors for the development of apps. Using the SDK, this WIPhas developed smart phone apps to read the current sensors, process them and       generate graphs. The data from these sensors can also be wirelessly       transmitted to other platforms (like other smart phones, IPads®, laptops etc.) for       further use. This WIP has used Excel® and Matlab® to process the data and       integrate it with a simulation to provide the student. All this makes the smart       phone a very powerful tool in the classroom.       Future plans include testing the apps and hardware in the classroom to study the       impact it has on student learning.Figure 1.
