IS impact factor around 2 good for bio-engineering field?
The go-to-place to look up Impact Factors (IF) is Web of Science's Journal Citation Reports (JCR). As it is a commercial product, you(r institution) needs a subscription to access it.

JCR puts journals into categories. In this case, Personal and Ubiquitous Computing is listed in the categories Telecommunications and Computer Science, Information Systems.


In Telecommunications, the journal ranks 53 out of 88 journals in Web of Science 2018 (the latest available). The first-ranked journal has an Impact Factor (IF) of 22.973, the last one 0.350, the median 2.274.
In Computer Science, Information Systems, the journal ranks 96 out of 155 journals. The first-ranked journal has an IF of 22.973 (the same as in the other category), the last one is 'not available' (the second-to-last is 0.282), the median is 2.170.
There is no category called 'Bioengineering' in JCR, but there is one called Engineering, Biomedical. It contains 80 journals, the highest IF is 17.135, the lowest is 0.452, and the median IF is 2.272.


Using these three categories as benchmarks to assess the journal's IF, one can see that the journal is always close to the median value, and therefore certainly okay. But whether it is 'good' or not for the purpose of your exercise you need to ask your instructor.
